<h2>Introduction</h2>
|
||||||
|
<p>The General-Purpose Input/Output (GPIO) gives access to the MCU pins.
|
||||||
|
The GPIO can be interfaced through a peripheral bus or the local bus.</p>
|
||||||
|
|
||||||
|
<p> </p>
|
||||||
|
|
||||||
|
<h2>GPIO Software Driver</h2>
|
||||||
|
|
||||||
|
<p>This driver provides an API to get access to the main features of the GPIO controller.</p>
|
||||||
|
<p> </p>
|
||||||
|
<p>The driver is composed of <a href="gpio.c">gpio.c</a> and <a href="gpio.h">gpio.h</a> (for accurate API description, read this header file).</p>
|
||||||
|
<p> </p>
|
||||||
|
|
||||||
|
<h2>GPIO Software Driver Examples</h2>
|
||||||
|
<p>Two examples are currently available:
|
||||||
|
<li><a href="./PERIPHERAL_BUS_EXAMPLE/readme.html"> demonstrates the peripheral bus interface</a>;</li>
|
||||||
|
<li><a href="./LOCAL_BUS_EXAMPLE/readme.html"> demonstrates the local bus interface</a>.</li>

// If a spurious interrupt occurs, the status register (SR) contains an

|
// interrupt, whatever the interrupt priority level causing the spurious

|
// event. This behavior has been chosen because a spurious interrupt has not
|
||||||
|
// to be a priority one and because it may not cause any trouble to other
|

// interrupts.

// However, these spurious interrupts place the hardware in an unstable state

// and could give problems in other/future versions of the CPU, so the

|
// software has to be written so that they never occur. The only safe way of

// achieving this is to always clear or disable peripheral interrupts with the
|
||||||
|
// following sequence:
|
||||||
|
// 1: Mask the interrupt in the CPU by setting GM (or IxM) in SR.
|
||||||
|
// 2: Perform the bus access to the peripheral register that clears or
|
||||||
|
// disables the interrupt.
|
||||||
|
// 3: Wait until the interrupt has actually been cleared or disabled by the
|
||||||
|
// peripheral. This is usually performed by reading from a register in the
|
||||||
|
// same peripheral (it DOES NOT have to be the same register that was
|
||||||
|
// accessed in step 2, but it MUST be in the same peripheral), what takes
|
||||||
|
// bus system latencies into account, but peripheral internal latencies
|
||||||
|
// (generally 0 cycle) also have to be considered.
|
||||||
|
// 4: Unmask the interrupt in the CPU by clearing GM (or IxM) in SR.
|
||||||
|
// Note that steps 1 and 4 are useless inside interrupt handlers as the
|
||||||
|
// corresponding interrupt level is automatically masked by IxM (unless IxM is
|
||||||
|
// explicitly cleared by the software).
|
||||||
|
//
|
||||||
|
// Get the right IRQ handler.
|
||||||
|
//
|

The PM module is very specific to the device it is integrated in. Thus instead
|
||||||
|
of providing one low-level software driver for all PM modules which could be
|
||||||
|
cumbersome to use and maintain, this folder contains instead several versions of
|
||||||
|
PM software drivers, depending on the device it was intended for.
|
||||||
|
|
||||||
|
Furthermore, the software drivers do not have the same API (mostly due to major
|
||||||
|
differences between PM module versions).
|
||||||
|
|
||||||
|
Note however that the power_clocks_lib.c/.h collection is destined to provide
|
||||||
|
a high-level API abstracting the existence of modules dealing with Power
|
||||||
|
Management and Clock configuration and System Control.
|
||||||
|
|
||||||
|
Here is a brief presentation of the files present in this folder:
|
||||||
|
- pm_at32ap7000.h, pm_at32ap7000.c: low-level software driver for a PM module
|
||||||
|
with version 100
|
||||||
|
|
||||||
|
- pm.c, pm.h: low-level software driver for a PM module with version 2xx
|
||||||
|
- pm_conf_clocks.c: Clocks configuration library relying on pm.c/.h for a PM
|
||||||
|
module with version 2xx. Its interface is available in pm.h.
|
||||||
|
|
||||||
|
- pm_uc3l.h, pm_uc3l.c: low-level software driver for the UC3L devices PM module
|
||||||
|
|
||||||
|
- pm_uc3c.h, pm_uc3c.c: low-level software driver for the UC3C devices PM module
|
||||||
|
|
||||||
|
- power_clocks_lib.h, power_clocks_lib.c: high-level library to abstract features
|
||||||
|
such as oscillators/pll/dfll configuration, clock configuration, System-sensible
|
||||||
|
parameters configuration, buses clocks configuration, sleep mode, reset. This
|
||||||
|
list of features being quite broad, an implementation of this library must
|
||||||
|
use several modules of a device.

<h2>Introduction</h2>
|
||||||
|
<h3>UC3A0/1, UC3B, UC3A3</h3>
|
||||||
|
<p>The Power Manager (PM) controls the oscillators and PLLs, and generates the clocks and
|
||||||
|
resets in the device. The PM controls two fast crystal oscillators, as well as two PLLs, which can
|
||||||
|
multiply the clock from either oscillator to provide higher frequencies. Additionally, a low-power
|
||||||
|
32 KHz oscillator is used to generate the real-time counter clock for high accuracy real-time
|
||||||
|
measurements. The PM also contains a low-power RC oscillator with fast start-up time, which
|
||||||
|
can be used to clock the digital logic.</p>
|
||||||
|
|
||||||
|
<h3> UC3L, UC3C </h3>
|
||||||
|
<p>The Power Manager (PM) provides synchronous clocks used to clock the main digital logic in the
|
||||||
|
device, namely the CPU, and the modules and peripherals connected to the HSB and PBx buses. The PM also
|
||||||
|
contains advanced power-saving features and a Reset Controller.</p>
|
||||||
|
|
||||||
|
|
||||||
|
<p> </p>
|
||||||

<h2>Power Manager Driver</h2>
|
||||||
|
<h3>UC3A0/1, UC3B, UC3A3</h3>
|

|
<p>The driver is composed of <a href="pm.c">pm.c</a> and <a href="pm.h">pm.h</a>.</p>
|
||||||
|
<p> </p>
|
||||||
|
<p>This driver provides interfaces for PM main hardware features:
|
||||||
|
|
||||||
|
<li>oscillator source setup: external or crystal;
|
||||||
|
<li>oscillator startup;
|
||||||
|
<li>PLL setup;
|
||||||
|
<li>main clock source setup.
|
||||||

<p>
|
||||||
|
The file <a href="pm_conf_clocks.c">pm_conf_clocks.c</a> provides functions to simplify the usage of this driver.
|

The file <a href="power_clocks_lib.c">power_clocks_lib.c</a> (and <a href="power_clocks_lib.h">power_clocks_lib.h</a>)
|
||||||
|
provides functions to abstract features such as oscillators/pll/dfll configuration, clock configuration, System-sensible

<h2>Introduction</h2>
|
||||||
|
<p>This driver will let you communicate through serial ports of all AVR®32 AT32UC3 devices.</p>
|
||||||
|
<p> </p>
|
||||||
|
|
||||||
|
The USART driver philosophy of usage is:
|
||||||
|
<li> Configure one (or several) USART in the wanted mode [usart_init_xxxxx]</li>
|
||||||
|
<li> Send or receive data on the configured USART, [usart_putchar, usart_getchar, usart_write_line, ...]</li>
|
||||||
|
|
||||||
|
<h2>USART Driver</h2>
|
||||||
|
<p>The driver is composed of <a href="usart.c">usart.c</a> and <a href="usart.h">usart.h</a>.</p>
|
||||||
|
</p>
|
||||||

/*
|
||||||
|
* This is a simple demo that creates a number of tasks from a pool of
|
||||||
|
* 'standard demo tasks' which are used by all the FreeRTOS port demos. The
|
||||||
|
* standard demo tasks don't provide any useful functionality other than to
|
||||||
|
* demonstrate the FreeRTOS API being used and show how the scheduler behaves.
|
||||||
|
*
|
||||||
|
* A COM test is included whereby one task transmits characters on the UART
|
||||||
|
* which are then received by another task. A loopback connector is required
|
||||||
|
* on the UART1 connector for this test to pass (pins 2 and 3 need to be
|
||||||
|
* connected together - a paper clip is usually all that is required). LED
|
||||||
|
* 5 red and green are under the control of the COM test tasks. Red will toggle
|
||||||
|
* each time a character is successfully transmitted, and the green LED toggles
|
||||||
|
* for each received character.
|
||||||
|
*
|
||||||
|
* In addition this file creates a 'Check' task. This periodically inspects
|
||||||
|
* the standard demo tasks and makes a few other simple tests to see if the
|
||||||
|
* system is performing as expected. The check task toggles LED 6 green every
|
||||||
|
* 3 seconds provided no errors exist and sets it to red if an error has
|
||||||
|
* occurred. The toggle rate will increase to 500ms if an error is detected
|
||||||
|
* at any time. This mechanism can be tested by removing the loopback
|
||||||
|
* connector from UART1, and in so doing deliberately generating an error in
|
||||||
|
* the COM test task.
|
||||||
|
*
|
||||||
|
* LED 1 through 4 are controlled by simple LED flashing tasks. Each should
|
||||||
|
* toggle at a fixed but different frequency.

|
* \brief AVR32 UC3 ISP trampoline.
|
||||||
|
*
|
||||||
|
* In order to be able to program a project with both BatchISP and JTAGICE mkII
|
||||||
|
* without having to take the general-purpose fuses into consideration, add this
|
||||||
|
* file to the project and change the program entry point to _trampoline.
|
||||||
|
*
|
||||||
|
* The pre-programmed ISP will be erased if JTAGICE mkII is used.
|
||||||
|
*
|
||||||
|
* - Compiler: GNU GCC for AVR32
|
||||||
|
* - Supported devices: All AVR32UC devices can be used.
