I compiled the code with 2010q1-188 version compiler without IDE. The firmware still cant run properly. Then I tried the code with main function commented in the IDE and found out the firmware generated by IDE can run properly. What may cause the difference. The modified code is pasted below. <pre><code>#include "wirish.h" #include "MapleFreeRTOS.h" #define PWM_PIN 2 void setup() { /* Set up the LED to blink */ pinMode(BOARD_LED_PIN, OUTPUT); /* Turn on PWM on pin PWM_PIN */ pinMode(PWM_PIN, PWM); pwmWrite(PWM_PIN, 0x8000); /* Send a message out USART2 */ Serial2.begin(9600); } /* Multi-task example */ void vTaskCodePing( void * pvParameters ) { while(1) { SerialUSB.print("Ping\n"); vTaskDelay(900); } } void vTaskCodePang( void * pvParameters ) { while(1) { SerialUSB.print("PANG\n"); vTaskDelay(900); } } #define STACK_SIZE 200 /* Please Do Not Remove & Edit Following Code */ void loop() { /* Create two tasks Ping and Pang */ xTaskCreate(vTaskCodePing, (const signed char*)"Ping", STACK_SIZE, NULL, 1, NULL); xTaskCreate(vTaskCodePang, (const signed char*)"Pang", STACK_SIZE, NULL, 1, NULL); vTaskStartScheduler(); } #if 1 int main(void) { setup(); while(1) { loop(); } return 0; } #endif</code></pre> hihohoho on "cant run freertos demo" http://forums.leaflabs.com/topic.php?id=74266#post-105200 Mon, 27 Jan 2014 09:15:31 +0000 hihohoho 105200@http://forums.leaflabs.com/ Have you tried "MapleFreeRTOS.h" ? The above code works fine in MapleFreeRTOS. You'll have to rewrite it to get rid of main() and put in loop() . Also replace delay() with vTaskDelay() as your just wasting processing cycles otherwise. breadbread1984 on "cant run freertos demo" http://forums.leaflabs.com/topic.php?id=74266#post-105199 Mon, 27 Jan 2014 07:25:09 +0000 breadbread1984 105199@http://forums.leaflabs.com/ I try to run a freertos demo on maple. After I upload the firmware, the /dev/ttyACM0 disappear as soon as the maple completes booting. I think there should be some problem with the firmware. There is the source of the firmware. Could someone find the problem of the source for me. thanks in advance. <pre><code>#include "wirish.h" #include "FreeRTOS.h" #include "task.h" #define PWM_PIN 2 void setup() { /* Set up the LED to blink */ pinMode(BOARD_LED_PIN, OUTPUT); /* Turn on PWM on pin PWM_PIN */ pinMode(PWM_PIN, PWM); pwmWrite(PWM_PIN, 0x8000); /* Send a message out USART2 */ Serial2.begin(9600); } /* Multi-task example */ void vTaskCodePing( void * pvParameters ) { while(1) { SerialUSB.print("Ping\n"); delay(900); } } void vTaskCodePang( void * pvParameters ) { while(1) { SerialUSB.print("PANG\n"); delay(900); } } #define STACK_SIZE 200 /* Please Do Not Remove & Edit Following Code */ int main(void) { setup(); /* Create two tasks Ping and Pang */ xTaskCreate(vTaskCodePing, (const signed char*)"Ping", STACK_SIZE, NULL, 1, NULL); xTaskCreate(vTaskCodePang, (const signed char*)"Pang", STACK_SIZE, NULL, 1, NULL); vTaskStartScheduler(); return 0; }</code></pre>
