This enables the * demo's to be executed on the RAM limited PIC-devices. * * The Demo1 project is configured for a PIC18F4620 device. Main.c starts 9 * tasks (including the idle task). * This first demo is included to do a quick check on the FreeRTOS * installation. It is also included to demonstrate a minimal project-setup * to use FreeRTOS in a wizC environment. * * Eight independant tasks are created. All tasks share the same taskcode. * Each task blinks a different led on portB. The blinkrate for each task * is different, but chosen in such a way that portB will show a binary * counter pattern. All blinkrates are derived from a single master-rate. * By default, this masterrate is set to 100 milliseconds. Although such * a low value will make it almost impossible to see some of the leds * actually blink, it is a good value when using the wizC-simulator. * When testing on a real chip, changing the value to eg. 500 milliseconds * would be appropiate. */ /* Scheduler include files. */ #include #include #define mainBLINK_LED_INTERVAL ( ( TickType_t ) 100 / ( portTICK_PERIOD_MS ) ) /* The LED that is flashed by the B0 task. */ #define mainBLINK_LED0_PORT LATD #define mainBLINK_LED0_TRIS TRISD #define mainBLINK_LED0_PIN 0 #define mainBLINK_LED0_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED0_PIN)) /* The LED that is flashed by the B1 task. */ #define mainBLINK_LED1_PORT LATD #define mainBLINK_LED1_TRIS TRISD #define mainBLINK_LED1_PIN 1 #define mainBLINK_LED1_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED1_PIN)) /* The LED that is flashed by the B2 task. */ #define mainBLINK_LED2_PORT LATD #define mainBLINK_LED2_TRIS TRISD #define mainBLINK_LED2_PIN 2 #define mainBLINK_LED2_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED2_PIN)) /* The LED that is flashed by the B3 task. */ #define mainBLINK_LED3_PORT LATD #define mainBLINK_LED3_TRIS TRISD #define mainBLINK_LED3_PIN 3 #define mainBLINK_LED3_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED3_PIN)) /* The LED that is flashed by the B4 task. */ #define mainBLINK_LED4_PORT LATD #define mainBLINK_LED4_TRIS TRISD #define mainBLINK_LED4_PIN 4 #define mainBLINK_LED4_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED4_PIN)) /* The LED that is flashed by the B5 task. */ #define mainBLINK_LED5_PORT LATD #define mainBLINK_LED5_TRIS TRISD #define mainBLINK_LED5_PIN 5 #define mainBLINK_LED5_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED5_PIN)) /* The LED that is flashed by the B6 task. */ #define mainBLINK_LED6_PORT LATD #define mainBLINK_LED6_TRIS TRISD #define mainBLINK_LED6_PIN 6 #define mainBLINK_LED6_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED6_PIN)) /* The LED that is flashed by the B7 task. */ #define mainBLINK_LED7_PORT LATD #define mainBLINK_LED7_TRIS TRISD #define mainBLINK_LED7_PIN 7 #define mainBLINK_LED7_INTERVAL ((mainBLINK_LED_INTERVAL) << (mainBLINK_LED7_PIN)) typedef struct { unsigned char *port; unsigned char *tris; unsigned char pin; TickType_t interval; } SBLINK; const SBLINK sled0 = {&mainBLINK_LED0_PORT, &mainBLINK_LED0_TRIS, mainBLINK_LED0_PIN, mainBLINK_LED0_INTERVAL}; const SBLINK sled1 = {&mainBLINK_LED1_PORT, &mainBLINK_LED1_TRIS, mainBLINK_LED1_PIN, mainBLINK_LED1_INTERVAL}; const SBLINK sled2 = {&mainBLINK_LED2_PORT, &mainBLINK_LED2_TRIS, mainBLINK_LED2_PIN, mainBLINK_LED2_INTERVAL}; const SBLINK sled3 = {&mainBLINK_LED3_PORT, &mainBLINK_LED3_TRIS, mainBLINK_LED3_PIN, mainBLINK_LED3_INTERVAL}; const SBLINK sled4 = {&mainBLINK_LED4_PORT, &mainBLINK_LED4_TRIS, mainBLINK_LED4_PIN, mainBLINK_LED4_INTERVAL}; const SBLINK sled5 = {&mainBLINK_LED5_PORT, &mainBLINK_LED5_TRIS, mainBLINK_LED5_PIN, mainBLINK_LED5_INTERVAL}; const SBLINK sled6 = {&mainBLINK_LED6_PORT, &mainBLINK_LED6_TRIS, mainBLINK_LED6_PIN, mainBLINK_LED6_INTERVAL}; const SBLINK sled7 = {&mainBLINK_LED7_PORT, &mainBLINK_LED7_TRIS, mainBLINK_LED7_PIN, mainBLINK_LED7_INTERVAL}; /* * The task code for the "vBlink" task. */ static portTASK_FUNCTION_PROTO(vBlink, pvParameters); /*-----------------------------------------------------------*/ /* * Creates the tasks, then starts the scheduler. */ void main( void ) { /* * Start the blink tasks defined in this file. */ xTaskCreate( vBlink, "B0", configMINIMAL_STACK_SIZE, &sled0, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B1", configMINIMAL_STACK_SIZE, &sled1, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B2", configMINIMAL_STACK_SIZE, &sled2, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B3", configMINIMAL_STACK_SIZE, &sled3, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B4", configMINIMAL_STACK_SIZE, &sled4, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B5", configMINIMAL_STACK_SIZE, &sled5, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B6", configMINIMAL_STACK_SIZE, &sled6, tskIDLE_PRIORITY, NULL ); xTaskCreate( vBlink, "B7", configMINIMAL_STACK_SIZE, &sled7, tskIDLE_PRIORITY, NULL ); /* * Start the scheduler. */ vTaskStartScheduler( ); while(1) /* This point should never be reached. */ { } } /*-----------------------------------------------------------*/ static portTASK_FUNCTION(vBlink, pvParameters) { unsigned char *Port = ((SBLINK *)pvParameters)->port; unsigned char *Tris = ((SBLINK *)pvParameters)->tris; unsigned char Pin = ((SBLINK *)pvParameters)->pin; TickType_t Interval = ((SBLINK *)pvParameters)->interval; TickType_t xLastWakeTime; /* * Initialize the hardware */ *Tris &= ~(1<
