+
+CMSIS Changes
+
+
+
+
+
+
+
+
+Changes to CMSIS version V1.20
+
+
+
+1. Removed CMSIS Middelware packages
+
+ CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found.
+
+
+2. SystemFrequency renamed to SystemCoreClock
+
+ The variable name SystemCoreClock is more precise than SystemFrequency
+ because the variable holds the clock value at which the core is running.
+
+
+3. Changed startup concept
+
+ The old startup concept (calling SystemInit_ExtMemCtl from startup file and calling SystemInit
+ from main) has the weakness that it does not work for controllers which need a already
+ configuerd clock system to configure the external memory controller.
+
+
+Changed startup concept
+
+ -
+ SystemInit() is called from startup file before premain.
+
+ -
+ SystemInit() configures the clock system and also configures
+ an existing external memory controller.
+
+ -
+ SystemInit() must not use global variables.
+
+ -
+ SystemCoreClock is initialized with a correct predefined value.
+
+ -
+ Additional function void SystemCoreClockUpdate (void) is provided.
+ SystemCoreClockUpdate() updates the variable SystemCoreClock
+ and must be called whenever the core clock is changed.
+ SystemCoreClockUpdate() evaluates the clock register settings and calculates
+ the current core clock.
+
+
+
+
+4. Advanced Debug Functions
+
+ ITM communication channel is only capable for OUT direction. To allow also communication for
+ IN direction a simple concept is provided.
+
+
+ -
+ Global variable volatile int ITM_RxBuffer used for IN data.
+
+ -
+ Function int ITM_CheckChar (void) checks if a new character is available.
+
+ -
+ Function int ITM_ReceiveChar (void) retrieves the new character.
+
+
+
+
+ For detailed explanation see file CMSIS debug support.htm.
+
+
+
+5. Core Register Bit Definitions
+
+ Files core_cm3.h and core_cm0.h contain now bit definitions for Core Registers. The name for the
+ defines correspond with the Cortex-M Technical Reference Manual.
+
+
+ e.g. SysTick structure with bit definitions
+
+
+/** @addtogroup CMSIS_CM3_SysTick CMSIS CM3 SysTick
+ memory mapped structure for SysTick
+ @{
+ */
+typedef struct
+{
+ __IO uint32_t CTRL; /*!< Offset: 0x00 SysTick Control and Status Register */
+ __IO uint32_t LOAD; /*!< Offset: 0x04 SysTick Reload Value Register */
+ __IO uint32_t VAL; /*!< Offset: 0x08 SysTick Current Value Register */
+ __I uint32_t CALIB; /*!< Offset: 0x0C SysTick Calibration Register */
+} SysTick_Type;
+
+/* SysTick Control / Status Register Definitions */
+#define SysTick_CTRL_COUNTFLAG_Pos 16 /*!< SysTick CTRL: COUNTFLAG Position */
+#define SysTick_CTRL_COUNTFLAG_Msk (1ul << SysTick_CTRL_COUNTFLAG_Pos) /*!< SysTick CTRL: COUNTFLAG Mask */
+
+#define SysTick_CTRL_CLKSOURCE_Pos 2 /*!< SysTick CTRL: CLKSOURCE Position */
+#define SysTick_CTRL_CLKSOURCE_Msk (1ul << SysTick_CTRL_CLKSOURCE_Pos) /*!< SysTick CTRL: CLKSOURCE Mask */
+
+#define SysTick_CTRL_TICKINT_Pos 1 /*!< SysTick CTRL: TICKINT Position */
+#define SysTick_CTRL_TICKINT_Msk (1ul << SysTick_CTRL_TICKINT_Pos) /*!< SysTick CTRL: TICKINT Mask */
+
+#define SysTick_CTRL_ENABLE_Pos 0 /*!< SysTick CTRL: ENABLE Position */
+#define SysTick_CTRL_ENABLE_Msk (1ul << SysTick_CTRL_ENABLE_Pos) /*!< SysTick CTRL: ENABLE Mask */
+
+/* SysTick Reload Register Definitions */
+#define SysTick_LOAD_RELOAD_Pos 0 /*!< SysTick LOAD: RELOAD Position */
+#define SysTick_LOAD_RELOAD_Msk (0xFFFFFFul << SysTick_LOAD_RELOAD_Pos) /*!< SysTick LOAD: RELOAD Mask */
+
+/* SysTick Current Register Definitions */
+#define SysTick_VAL_CURRENT_Pos 0 /*!< SysTick VAL: CURRENT Position */
+#define SysTick_VAL_CURRENT_Msk (0xFFFFFFul << SysTick_VAL_CURRENT_Pos) /*!< SysTick VAL: CURRENT Mask */
+
+/* SysTick Calibration Register Definitions */
+#define SysTick_CALIB_NOREF_Pos 31 /*!< SysTick CALIB: NOREF Position */
+#define SysTick_CALIB_NOREF_Msk (1ul << SysTick_CALIB_NOREF_Pos) /*!< SysTick CALIB: NOREF Mask */
+
+#define SysTick_CALIB_SKEW_Pos 30 /*!< SysTick CALIB: SKEW Position */
+#define SysTick_CALIB_SKEW_Msk (1ul << SysTick_CALIB_SKEW_Pos) /*!< SysTick CALIB: SKEW Mask */
+
+#define SysTick_CALIB_TENMS_Pos 0 /*!< SysTick CALIB: TENMS Position */
+#define SysTick_CALIB_TENMS_Msk (0xFFFFFFul << SysTick_VAL_CURRENT_Pos) /*!< SysTick CALIB: TENMS Mask */
+/*@}*/ /* end of group CMSIS_CM3_SysTick */
+
+7. DoxyGen Tags
+
+ DoxyGen tags in files core_cm3.[c,h] and core_cm0.[c,h] are reworked to create proper documentation
+ using DoxyGen.
+
+
+8. Folder Structure
+
+ The folder structure is changed to differentiate the single support packages.

+
+9. Open Points
+
+ Following points need to be clarified and solved:
+
+
+ -
+
+ Equivalent C and Assembler startup files.
+
+
+ Is there a need for having C startup files although assembler startup files are
+ very efficient and do not need to be changed?
+
+
+ -
+
+ Placing of HEAP in external RAM.
+
+
+ It must be possible to place HEAP in external RAM if the device supports an
+ external memory controller.
+
+
+ -
+
+ Placing of STACK /HEAP.
+
+
+ STACK should always be placed at the end of internal RAM.
+
+
+ If HEAP is placed in internal RAM than it should be placed after RW ZI section.
+
+
+ -
+
+ Removing core_cm3.c and core_cm0.c.
+
+
+ On a long term the functions in core_cm3.c and core_cm0.c must be replaced with
+ appropriate compiler intrinsics.
+
+
+
+
+
+10. Limitations
+
+ The following limitations are not covered with the current CMSIS version:
+
+
+ -
+ No C startup files for ARM toolchain are provided.
+
+ -
+ No C startup files for GNU toolchain are provided.
+
+ -
+ No C startup files for IAR toolchain are provided.
+
+ -
+ No Tasking projects are provided yet.

+
+CMSIS Debug Support
+
+
+
+Cortex-M3 ITM Debug Access
+
+ The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that provides together with
+ the Serial Viewer Output trace capabilities for the microcontroller system. The ITM has
+ 32 communication channels which are able to transmit 32 / 16 / 8 bit values; two ITM
+ communication channels are used by CMSIS to output the following information:
+
+
+ - ITM Channel 0: used for printf-style output via the debug interface.
+ - ITM Channel 31: is reserved for RTOS kernel awareness debugging.
+
+
+Debug IN / OUT functions
+CMSIS provides following debug functions:
+
+ - ITM_SendChar (uses ITM channel 0)
+ - ITM_ReceiveChar (uses global variable)
+ - ITM_CheckChar (uses global variable)
+
+
+ITM_SendChar
+
+ ITM_SendChar is used to transmit a character over ITM channel 0 from
+ the microcontroller system to the debug system.
+ Only a 8 bit value is transmitted.
+
+
+static __INLINE uint32_t ITM_SendChar (uint32_t ch)
+{
+ /* check if debugger connected and ITM channel enabled for tracing */
+ if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
+ (ITM->TCR & ITM_TCR_ITMENA) &&
+ (ITM->TER & (1UL << 0)) )
+ {
+ while (ITM->PORT[0].u32 == 0);
+ ITM->PORT[0].u8 = (uint8_t)ch;
+ }
+ return (ch);
+}
+
+ITM_ReceiveChar
+
+ ITM communication channel is only capable for OUT direction. For IN direction
+ a globel variable is used. A simple mechansim detects if a character is received.
+ The project to test need to be build with debug information.
+
+
+
+ The globale variable ITM_RxBuffer is used to transmit a 8 bit value from debug system
+ to microcontroller system. ITM_RxBuffer is 32 bit wide to enshure a proper handshake.
+
+
+extern volatile int ITM_RxBuffer; /* variable to receive characters */
+
+
+ A dedicated bit pattern is used to determin if ITM_RxBuffer is empty
+ or contains a valid value.
+
+
+#define ITM_RXBUFFER_EMPTY 0x5AA55AA5 /* value identifying ITM_RxBuffer is ready for next character */
+
+
+ ITM_ReceiveChar is used to receive a 8 bit value from the debug system. The function is nonblocking.
+ It returns the received character or '-1' if no character was available.
+
+
+static __INLINE int ITM_ReceiveChar (void) {
+ int ch = -1; /* no character available */
+
+ if (ITM_RxBuffer != ITM_RXBUFFER_EMPTY) {
+ ch = ITM_RxBuffer;
+ ITM_RxBuffer = ITM_RXBUFFER_EMPTY; /* ready for next character */
+ }
+
+ return (ch);
+}
+
+
+ITM_CheckChar
+
+ ITM_CheckChar is used to check if a character is received.
+
+
+static __INLINE int ITM_CheckChar (void) {
+
+ if (ITM_RxBuffer == ITM_RXBUFFER_EMPTY) {
+ return (0); /* no character available */
+ } else {
+ return (1); /* character available */
+ }
+}
+
+
+ITM Debug Support in uVision
+
+ uVision uses in a debug session the Debug (printf) Viewer window to
+ display the debug data.
+
+Direction microcontroller system -> uVision:
+
+ -
+ Characters received via ITM communication channel 0 are written in a printf style
+ to Debug (printf) Viewer window.
+
+
+
+Direction uVision -> microcontroller system:
+
+ - Check if ITM_RxBuffer variable is available (only performed once).
+ - Read character from Debug (printf) Viewer window.
+ - If ITM_RxBuffer empty write character to ITM_RxBuffer.
+
+
+Note
+
+
+RTX Kernel awareness in uVision
+
+ uVision / RTX are using a simple and efficient solution for RTX Kernel awareness.
+ No format overhead is necessary.
+ uVsion debugger decodes the RTX events via the 32 / 16 / 8 bit ITM write access
+ to ITM communication channel 31.
+
+
+Following RTX events are traced:
+
+ - Task Create / Delete event
+
+ - 32 bit access. Task start address is transmitted
+ - 16 bit access. Task ID and Create/Delete flag are transmitted
+ High byte holds Create/Delete flag, Low byte holds TASK ID.
+
+
+
+ - Task switch event
+
+ - 8 bit access. Task ID of current task is transmitted
+

+
+
+About
+
+
+ The Cortex Microcontroller Software Interface Standard (CMSIS) answers the challenges
+ that are faced when software components are deployed to physical microcontroller devices based on a
+ Cortex-M0 or Cortex-M3 processor. The CMSIS will be also expanded to future Cortex-M
+ processor cores (the term Cortex-M is used to indicate that). The CMSIS is defined in close co-operation
+ with various silicon and software vendors and provides a common approach to interface to peripherals,
+ real-time operating systems, and middleware components.
+
+
+ARM provides as part of the CMSIS the following software layers that are
+available for various compiler implementations:
+
+ - Core Peripheral Access Layer: contains name definitions,
+ address definitions and helper functions to
+ access core registers and peripherals. It defines also a device
+ independent interface for RTOS Kernels that includes debug channel
+ definitions.
+
+
+These software layers are expanded by Silicon partners with:
+
+ - Device Peripheral Access Layer: provides definitions
+ for all device peripherals
+ - Access Functions for Peripherals (optional): provides
+ additional helper functions for peripherals
+
+
+CMSIS defines for a Cortex-M Microcontroller System:
+
+ - A common way to access peripheral registers
+ and a common way to define exception vectors.
+ - The register names of the Core
+ Peripherals and the names of the Core
+ Exception Vectors.
+ - An device independent interface for RTOS Kernels including a debug
+ channel.
+
+
+
+ By using CMSIS compliant software components, the user can easier re-use template code.
+ CMSIS is intended to enable the combination of software components from multiple middleware vendors.
+
+
+Coding Rules and Conventions
+
+
+ The following section describes the coding rules and conventions used in the CMSIS
+ implementation. It contains also information about data types and version number information.
+
+
+Essentials
+
+ - The CMSIS C code conforms to MISRA 2004 rules. In case of MISRA violations,
+ there are disable and enable sequences for PC-LINT inserted.
+ - ANSI standard data types defined in the ANSI C header file
+ <stdint.h> are used.
+ - #define constants that include expressions must be enclosed by
+ parenthesis.
+ - Variables and parameters have a complete data type.
+ - All functions in the Core Peripheral Access Layer are
+ re-entrant.
+ - The Core Peripheral Access Layer has no blocking code
+ (which means that wait/query loops are done at other software layers).
+ - For each exception/interrupt there is definition for:
+
+ - an exception/interrupt handler with the postfix _Handler
+ (for exceptions) or _IRQHandler (for interrupts).
+ - a default exception/interrupt handler (weak definition) that contains an endless loop.
+ - a #define of the interrupt number with the postfix _IRQn.
+
+
+

+The CMSIS recommends the following conventions for identifiers.
+
+ - CAPITAL names to identify Core Registers, Peripheral Registers, and CPU Instructions.
+ - CamelCase names to identify peripherals access functions and interrupts.
+ - PERIPHERAL_ prefix to identify functions that belong to specify peripherals.
+ - Doxygen comments for all functions are included as described under Function Comments below.

+Data Types and IO Type Qualifiers
+
+
+ The Cortex-M HAL uses the standard types from the standard ANSI C header file
+ <stdint.h>. IO Type Qualifiers are used to specify the access
+ to peripheral variables. IO Type Qualifiers are indented to be used for automatic generation of
+ debug information of peripheral registers.

+
+
+ The file device.h is provided by the silicon vendor and is the
+ central include file that the application programmer is using in
+ the C source code. This file contains:
+
+
+ -
+
Interrupt Number Definition: provides interrupt numbers
+ (IRQn) for all core and device specific exceptions and interrupts.
+
+ -
+
Configuration for core_cm0.h / core_cm3.h: reflects the
+ actual configuration of the Cortex-M processor that is part of the actual
+ device. As such the file core_cm0.h / core_cm3.h is included that
+ implements access to processor registers and core peripherals.

+ for all device peripherals. It contains all data structures and the address
+ mapping for the device specific peripherals.
+
+ - Access Functions for Peripherals (optional): provides
+ additional helper functions for peripherals that are useful for programming

+
+
+
+Interrupt Number Definition
+
+To access the device specific interrupts the device.h file defines IRQn
+numbers for the complete device using a enum typedef as shown below:
+

+ file must contain a vendor specific implementation of this function. |
+
+
+
+
+
+Device Peripheral Access Layer
+
+ Each peripheral uses a prefix which consists of <device abbreviation>_
+ and <peripheral name>_ to identify peripheral registers that access this
+ specific peripheral. The intention of this is to avoid name collisions caused
+ due to short names. If more than one peripheral of the same type exists,
+ identifiers have a postfix (digit or letter). For example:
+
+
+ - <device abbreviation>_UART_Type: defines the generic register layout for all UART channels in a device.
+
+typedef struct
+{
+ union {
+ __I uint8_t RBR; /*!< Offset: 0x000 Receiver Buffer Register */
+ __O uint8_t THR; /*!< Offset: 0x000 Transmit Holding Register */
+ __IO uint8_t DLL; /*!< Offset: 0x000 Divisor Latch LSB */
+ uint32_t RESERVED0;
+ };
+ union {
+ __IO uint8_t DLM; /*!< Offset: 0x004 Divisor Latch MSB */
+ __IO uint32_t IER; /*!< Offset: 0x004 Interrupt Enable Register */
+ };
+ union {
+ __I uint32_t IIR; /*!< Offset: 0x008 Interrupt ID Register */
+ __O uint8_t FCR; /*!< Offset: 0x008 FIFO Control Register */
+ };
+ __IO uint8_t LCR; /*!< Offset: 0x00C Line Control Register */
+ uint8_t RESERVED1[7];
+ __I uint8_t LSR; /*!< Offset: 0x014 Line Status Register */
+ uint8_t RESERVED2[7];
+ __IO uint8_t SCR; /*!< Offset: 0x01C Scratch Pad Register */
+ uint8_t RESERVED3[3];
+ __IO uint32_t ACR; /*!< Offset: 0x020 Autobaud Control Register */
+ __IO uint8_t ICR; /*!< Offset: 0x024 IrDA Control Register */
+ uint8_t RESERVED4[3];
+ __IO uint8_t FDR; /*!< Offset: 0x028 Fractional Divider Register */
+ uint8_t RESERVED5[7];
+ __IO uint8_t TER; /*!< Offset: 0x030 Transmit Enable Register */
+ uint8_t RESERVED6[39];
+ __I uint8_t FIFOLVL; /*!< Offset: 0x058 FIFO Level Register */
+} LPC_UART_TypeDef;
+
+ - <device abbreviation>_UART1: is a pointer to a register structure that refers to a specific UART.
+ For example UART1->DR is the data register of UART1.
+
+#define LPC_UART2 ((LPC_UART_TypeDef *) LPC_UART2_BASE )
+#define LPC_UART3 ((LPC_UART_TypeDef *) LPC_UART3_BASE )
+
+
+
+Minimal Requiements
+
+ To access the peripheral registers and related function in a device the files device.h
+ and core_cm0.h / core_cm3.h defines as a minimum:
+
+
+ - The Register Layout Typedef for each peripheral that defines all register names.
+ Names that start with RESERVE are used to introduce space into the structure to adjust the addresses of
+ the peripheral registers. For example:
+
+typedef struct {
+ __IO uint32_t CTRL; /* SysTick Control and Status Register */
+ __IO uint32_t LOAD; /* SysTick Reload Value Register */
+ __IO uint32_t VAL; /* SysTick Current Value Register */
+ __I uint32_t CALIB; /* SysTick Calibration Register */
+ } SysTick_Type;
+
+
+ -
+ Base Address for each peripheral (in case of multiple peripherals
+ that use the same register layout typedef multiple base addresses are defined). For example:
+
+#define SysTick_BASE (SCS_BASE + 0x0010) /* SysTick Base Address */
+
+
+ -
+ Access Definition for each peripheral (in case of multiple peripherals that use
+ the same register layout typedef multiple access definitions exist, i.e. LPC_UART0,
+ LPC_UART2). For Example:
+
+#define SysTick ((SysTick_Type *) SysTick_BASE) /* SysTick access definition */
+
+
+
+
+ These definitions allow to access the peripheral registers from user code with simple assignments like:
+
+SysTick->CTRL = 0;
+
+Optional Features
+In addition the device.h file may define:
+
+ -
+ #define constants that simplify access to the peripheral registers.
+ These constant define bit-positions or other specific patterns are that required for the
+ programming of the peripheral registers. The identifiers used start with
+ <device abbreviation>_ and <peripheral name>_.
+ It is recommended to use CAPITAL letters for such #define constants.
+
+ -
+ Functions that perform more complex functions with the peripheral (i.e. status query before
+ a sending register is accessed). Again these function start with
+ <device abbreviation>_ and <peripheral name>_.
+
+
+
+core_cm0.h and core_cm0.c
+
+ File core_cm0.h describes the data structures for the Cortex-M0 core peripherals and does
+ the address mapping of this structures. It also provides basic access to the Cortex-M0 core registers
+ and core peripherals with efficient functions (defined as static inline).
+
+
+ File core_cm0.c defines several helper functions that access processor registers.
+
+Together these files implement the Core Peripheral Access Layer for a Cortex-M0.
+
+core_cm3.h and core_cm3.c
+
+ File core_cm3.h describes the data structures for the Cortex-M3 core peripherals and does
+ the address mapping of this structures. It also provides basic access to the Cortex-M3 core registers
+ and core peripherals with efficient functions (defined as static inline).
+
+
+ File core_cm3.c defines several helper functions that access processor registers.
+
+Together these files implement the Core Peripheral Access Layer for a Cortex-M3.
+
+startup_device
+
+ A template file for startup_device is provided by ARM for each supported
+ compiler. It is adapted by the silicon vendor to include interrupt vectors for all device specific
+ interrupt handlers. Each interrupt handler is defined as weak function
+ to an dummy handler. Therefore the interrupt handler can be directly used in application software
+ without any requirements to adapt the startup_device file.
+
+
+ The following exception names are fixed and define the start of the vector table for a Cortex-M0:
+
+
+__Vectors DCD __initial_sp ; Top of Stack
+ DCD Reset_Handler ; Reset Handler
+ DCD NMI_Handler ; NMI Handler
+ DCD HardFault_Handler ; Hard Fault Handler

+; External Interrupts
+ DCD WWDG_IRQHandler ; Window Watchdog
+ DCD PVD_IRQHandler ; PVD through EXTI Line detect
+ DCD TAMPER_IRQHandler ; Tamper
+
+
+ Device specific interrupts must have a dummy function that can be overwritten in user code.
+ Below is an example for this dummy function.
+
+
+Default_Handler PROC

+
+system_device.c
+
+ A template file for system_device.c is provided by ARM but adapted by
+ the silicon vendor to match their actual device. As a minimum requirement
+ this file must provide a device specific system configuration function and a global variable
+ that contains the system frequency. It configures the device and initializes typically the
+ oscillator (PLL) that is part of the microcontroller device.
+
+
+ The file system_device.c must provide
+ as a minimum requirement the SystemInit function as shown below.
+
+
+
+
+
+ Function Definition |
+ Description |
+
+
+ void SystemInit (void) |
+ Setup the microcontroller system. Typically this function configures the
+ oscillator (PLL) that is part of the microcontroller device. For systems
+ with variable clock speed it also updates the variable SystemCoreClock.
+ SystemInit is called from startup_device file. |
+
+
+ void SystemCoreClockUpdate (void) |
+ Updates the variable SystemCoreClock and must be called whenever the
+ core clock is changed during program execution. SystemCoreClockUpdate()
+ evaluates the clock register settings and calculates the current core clock.
+ |
+
+
+
+
+
+ Also part of the file system_device.c
+ is the variable SystemCoreClock which contains the current CPU clock speed shown below.
+
+
+
+
+
+ Variable Definition |
+ Description |
+
+
+ uint32_t SystemCoreClock |
+ Contains the system core clock (which is the system clock frequency supplied
+ to the SysTick timer and the processor core clock). This variable can be
+ used by the user application to setup the SysTick timer or configure other
+ parameters. It may also be used by debugger to query the frequency of the
+ debug timer or configure the trace clock speed.
+ SystemCoreClock is initialized with a correct predefined value.
+ The compiler must be configured to avoid the removal of this variable in
+ case that the application program is not using it. It is important for
+ debug systems that the variable is physically present in memory so that
+ it can be examined to configure the debugger. |

+NVIC Access Functions
+
+ The CMSIS provides access to the NVIC via the register interface structure and several helper
+ functions that simplify the setup of the NVIC. The CMSIS HAL uses IRQ numbers (IRQn) to
+ identify the interrupts. The first device interrupt has the IRQn value 0. Therefore negative
+ IRQn values are used for processor core exceptions.
+
+
+ For the IRQn values of core exceptions the file device.h provides
+ the following enum names.

+SysTick Configuration Function
+
+The following function is used to configure the SysTick timer and start the
+SysTick interrupt.
+
+
+
+
+ Name |
+ Parameter |
+ Description |
+
+
+ uint32_t SysTickConfig
+ (uint32_t ticks) |
+ ticks is SysTick counter reload value |
+ Setup the SysTick timer and enable the SysTick interrupt. After this
+ call the SysTick timer creates interrupts with the specified time
+ interval.
+
+ Return: 0 when successful, 1 on failure.

+
+Cortex-M3 ITM Debug Access
+
+The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that
+provides together with the Serial Viewer Output trace capabilities for the
+microcontroller system. The ITM has 32 communication channels; two ITM
+communication channels are used by CMSIS to output the following information:
+
+ - ITM Channel 0: implements the ITM_SendChar function
+ which can be used for printf-style output via the debug interface.
+ - ITM Channel 31: is reserved for the RTOS kernel and can be used for
+ kernel awareness debugging.
+
+Note
+
+ The ITM channel 31 is selected for the RTOS kernel since some kernels
+ may use the Privileged level for program execution. ITM
+ channels have 4 groups with 8 channels each, whereby each group can be
+ configured for access rights in the Unprivileged level. The ITM channel 0
+ may be therefore enabled for the user task whereas ITM channel 31 may be
+ accessible only in Privileged level from the RTOS kernel itself.
+
+
+
+The prototype of the ITM_SendChar routine is shown in the
+table below.
+
+
+
+
+ Name |
+ Parameter |
+ Description |
+
+
+ void uint32_t ITM_SendChar(uint32_t chr) |
+ character to output |
+ The function outputs a character via the ITM channel 0. The
+ function returns when no debugger is connected that has booked the
+ output. It is blocking when a debugger is connected, but the
+ previous character send is not transmitted.
+ Return: the input character 'chr'. |
+
+
+
+
+
+ Example for the usage of the ITM Channel 31 for RTOS Kernels:
+
+
+ // check if debugger connected and ITM channel enabled for tracing
+ if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
+ (ITM->TCR & ITM_TCR_ITMENA) &&
+ (ITM->TER & (1UL << 31))) {
+ // transmit trace data
+ while (ITM->PORT31_U32 == 0);
+ ITM->PORT[31].u8 = task_id; // id of next task
+ while (ITM->PORT[31].u32 == 0);
+ ITM->PORT[31].u32 = task_status; // status information
+ }
+
+
+Cortex-M3 additional Debug Access
+
+CMSIS provides additional debug functions to enlarge the Cortex-M3 Debug Access.
+Data can be transmitted via a certain global buffer variable towards the target system.
+
+The buffer variable and the prototypes of the additional functions are shown in the
+table below.
+
+
+
+
+ Name |
+ Parameter |
+ Description |
+
+
+ extern volatile int ITM_RxBuffer |
+ |
+ Buffer to transmit data towards debug system.
+ Value 0x5AA55AA5 indicates that buffer is empty. |
+
+
+ int ITM_ReceiveChar (void) |
+ none |
+ The nonblocking functions returns the character stored in
+ ITM_RxBuffer.
+ Return: -1 indicates that no character was received. |
+
+
+ int ITM_CheckChar (void) |
+ none |
+ The function checks if a character is available in ITM_RxBuffer.
+ Return: 1 indicates that a character is available, 0 indicates that
+ no character is available. |
+
+
+
+
+
+CMSIS Example
+
+ The following section shows a typical example for using the CMSIS layer in user applications.
+ The example is based on a STM32F10x Device.
+
+
+#include "stm32f10x.h"
+
+volatile uint32_t msTicks; /* timeTicks counter */
+
+void SysTick_Handler(void) {
+ msTicks++; /* increment timeTicks counter */
+}
+
+__INLINE static void Delay (uint32_t dlyTicks) {
+ uint32_t curTicks = msTicks;
+
+ while ((msTicks - curTicks) < dlyTicks);
+}
+
+__INLINE static void LED_Config(void) {
+ ; /* Configure the LEDs */
+}
+
+__INLINE static void LED_On (uint32_t led) {
+ ; /* Turn On LED */
+}
+
+__INLINE static void LED_Off (uint32_t led) {
+ ; /* Turn Off LED */
+}
+
+int main (void) {
+ if (SysTick_Config (SystemCoreClock / 1000)) { /* Setup SysTick for 1 msec interrupts */
+ ; /* Handle Error */
+ while (1);
+ }
+
+ LED_Config(); /* configure the LEDs */
+
+ while(1) {
+ LED_On (0x100); /* Turn on the LED */
+ Delay (100); /* delay 100 Msec */
+ LED_Off (0x100); /* Turn off the LED */
+ Delay (100); /* delay 100 Msec */
+ }
+}

+ *
+ * I2C State Monitoring Functions
+ *
+ ****************************************************************************************
+ * This I2C driver provides three different ways for I2C state monitoring
+ * depending on the application requirements and constraints:
+ *
+ *
+ * 1) Basic state monitoring:
+ * Using I2C_CheckEvent() function:
+ * It compares the status registers (SR1 and SR2) content to a given event
+ * (can be the combination of one or more flags).
+ * It returns SUCCESS if the current status includes the given flags
+ * and returns ERROR if one or more flags are missing in the current status.
+ * - When to use:
+ * - This function is suitable for most applications as well as for startup
+ * activity since the events are fully described in the product reference manual
+ * (RM0008).
+ * - It is also suitable for users who need to define their own events.
+ * - Limitations:
+ * - If an error occurs (ie. error flags are set besides to the monitored flags),
+ * the I2C_CheckEvent() function may return SUCCESS despite the communication
+ * hold or corrupted real state.
+ * In this case, it is advised to use error interrupts to monitor the error
+ * events and handle them in the interrupt IRQ handler.
+ *
+ * @note
+ * For error management, it is advised to use the following functions:
+ * - I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
+ * - I2Cx_ER_IRQHandler() which is called when the error interurpt occurs.
+ * Where x is the peripheral instance (I2C1, I2C2 ...)
+ * - I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the I2Cx_ER_IRQHandler() function
+ * in order to determine which error occured.
+ * - I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd() and/or I2C_GenerateStop()
+ * in order to clear the error flag and source and return to correct
+ * communication status.
+ *
+ *
+ * 2) Advanced state monitoring:
+ * Using the function I2C_GetLastEvent() which returns the image of both status
+ * registers in a single word (uint32_t) (Status Register 2 value is shifted left
+ * by 16 bits and concatenated to Status Register 1).
+ * - When to use:
+ * - This function is suitable for the same applications above but it allows to
+ * overcome the limitations of I2C_GetFlagStatus() function (see below).
+ * The returned value could be compared to events already defined in the
+ * library (stm32f10x_i2c.h) or to custom values defined by user.
+ * - This function is suitable when multiple flags are monitored at the same time.
+ * - At the opposite of I2C_CheckEvent() function, this function allows user to
+ * choose when an event is accepted (when all events flags are set and no
+ * other flags are set or just when the needed flags are set like
+ * I2C_CheckEvent() function).
+ * - Limitations:
+ * - User may need to define his own events.
+ * - Same remark concerning the error management is applicable for this
+ * function if user decides to check only regular communication flags (and
+ * ignores error flags).
+ *
+ *
+ * 3) Flag-based state monitoring:
+ * Using the function I2C_GetFlagStatus() which simply returns the status of
+ * one single flag (ie. I2C_FLAG_RXNE ...).
+ * - When to use:
+ * - This function could be used for specific applications or in debug phase.
+ * - It is suitable when only one flag checking is needed (most I2C events
+ * are monitored through multiple flags).
+ * - Limitations:
+ * - When calling this function, the Status register is accessed. Some flags are
+ * cleared when the status register is accessed. So checking the status
+ * of one Flag, may clear other ones.
+ * - Function may need to be called twice or more in order to monitor one
+ * single event.
