mbed
...If you are talking about the mbed board: ARM mbed LPC1768 Board and using the online mbed compiler, adding FreeRTOS is fairly easy. Under your project in the compiler, go to import and search "freertos". Import this library:
Make sure to include "FreeRTOS.h" in your project!
- Tested example:
<cpp> // N.C. Freertos mbed minimal example based on below: // https://developer.mbed.org/users/rgrover1/code/FreeRTOS/ // http://www.radekdostal.com/content/freertos-610-minimal-example // 20/04/2017 update: Compiled for and NUCLEO-F104RB, without errors // Complile without errors: LPC1768,NUCLEO-F104RB,F401RE,L152RE // Compilation Errors for: EA LPC11U35, TG-LPC11U35-501 nRF51822, FRDM-K25Z, // nRF52-DK,BBC micro:bit,LPC1114FN28, NUCLEO-F030R8 // NUCLEO-F746ZG, LPC800-MAX
- include "mbed.h"
- include "FreeRTOS.h"
- include "task.h"
DigitalOut led1(LED1); DigitalOut led2(LED2);
void Task1 (void* pvParameters) {
(void) pvParameters; // Just to stop compiler warnings.
for (;;) {
led1 = !led1;
printf("Task1\n");
vTaskDelay(500);
}
}
void Task2 (void* pvParameters) {
(void) pvParameters; // Just to stop compiler warnings.
for (;;) {
led2= !led2;
printf("Task2\n");
vTaskDelay(5000);
}
}
int main (void) {
xTaskCreate( Task1, ( signed char * ) "Task1", configMINIMAL_STACK_SIZE, NULL, tskIDLE_PRIORITY, ( xTaskHandle * ) NULL );
xTaskCreate( Task2, ( signed char * ) "Task2", configMINIMAL_STACK_SIZE, NULL, tskIDLE_PRIORITY, ( xTaskHandle * ) NULL );
vTaskStartScheduler();
//should never get here
printf("ERORR: vTaskStartScheduler returned!");
for (;;);
} </cpp>
