Hi all, I’m trying to run FreeRTOS on Arduino Uno board using eclipse (mars version) IDE. I did setting up Eclipse for developing freeRTOS applications on Arduino. I installed AVR Eclipse Plugin &WinAVR-20100110.
I created C++ Empty project(AVR Cross Target Application) and Freertos Library (AVR Cross Target Static library)
Simple freertos led blink program I wrote and it compiled successfully.
code:
#include <Arduino_FreeRTOS.h>
// define two tasks for Blink & AnalogRead
void TaskBlink( void *pvParameters );
void TaskAnalogRead( void *pvParameters );
// the setup function runs once when you press reset or power the board
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB, on LEONARDO, MICRO, YUN, and other 32u4 based boards.
}
// Now set up two tasks to run independently.
xTaskCreate(
TaskBlink
, "Blink" // A name just for humans
, 128 // This stack size can be checked & adjusted by reading the Stack Highwater
, NULL
, 2 // Priority, with 3 (configMAX_PRIORITIES - 1) being the highest, and 0 being the lowest.
, NULL );
xTaskCreate(
TaskAnalogRead
, "AnalogRead"
, 128 // Stack size
, NULL
, 1 // Priority
, NULL );
// Now the task scheduler, which takes over control of scheduling individual tasks, is automatically started.
}
void loop()
{
// Empty. Things are done in Tasks.
}
/*--------------------------------------------------*/
/*---------------------- Tasks ---------------------*/
/*--------------------------------------------------*/
void TaskBlink(void *pvParameters) // This is a task.
{
(void) pvParameters;
// initialize digital LED_BUILTIN on pin 13 as an output.
pinMode(LED_BUILTIN, OUTPUT);
for ( ;; ) // A Task shall never return or exit.
{
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
vTaskDelay( 1000 / portTICK_PERIOD_MS ); // wait for one second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
vTaskDelay( 1000 / portTICK_PERIOD_MS ); // wait for one second
}
}
void TaskAnalogRead(void *pvParameters) // This is a task.
{
(void) pvParameters;
for ( ;; )
{
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
vTaskDelay(1); // one tick delay (15ms) in between reads for stability
}
}
Then I upload the code to the arduino uno board, but I’m not able to see any output on Arduino board.
Is there any issue on freertos code side?? or Freertos library??
Also I cannot do debug here, can anyone tell me how to debug this ??
I don’t know I summarize all the things here, if any more details needed for answering me this question please ask me.
