FreeRTOS With Arduino Tutorials 2 - How to Handle Tasks with FreeRTOS on Arduino.

In this video, we will know how to handle Tasks with FreeRTOS on Arduino.
FreeRTOS: Free Real Time Operating System

Create task function:
void TaskBlink( void *pvParameters )

Create Handle task:
TaskHandle_t TaskHandle_1

Create task:
xTaskCreate(TaskBlink, "Task1", 100, NULL, 2, &TaskHandle_1);
// First param : Function you want to create
// Second param : Name of task
// Third param : Stack memory size
// Fourth param : Param (we don't transfer param so we put it NULL)
// Fifth param : Priority (The highest priority will run first - adding tasks until you run out of RAM)
// Last param : Reference(&) Handletask

Create delay (less accuracy):
vTaskDelay( 1000 / portTICK_PERIOD_MS ); // run per second

Background:
- We don't need to put source code in side void loop() function
- Inside task function, we need to put INFINITE loop:
- while(1) or for(;;)

This functionality implemented using freertos can be do using a non blocking delay (use millia) to print once a second in the loop along with a simple if else to control the led using button after the print code.
Tried and tested this and it works.

I feel like you should have the while after the digital write, that makes more sense when reading the code. It writes low and then while haults everything until false is returned.

where is xTaskCreate? is it a built in function?? i am new to rtos from where should i start? can i start directly freertos with arduino?

[jibrilsoodeen]

thansk for all the help bro, keep it up

[beaconing]

this is great ! but even better if there is a subtitle 😀

[muhammadifwatarifbinothman]

if i want to transfer two argument (in and out) of the Task_Print1, how to do that?

[rthu]

Why are you casting to void? Why cast at all if you are not using the params?

anh ơi cho em hỏi, em có thể lấy output của 1 task để dùng cho task khác được không, nếu được thì làm như thế nào ạ, em cảm ơn.

Please make such a advance video recording arduino . Nice video

Can you please share the circuit diagram.
