xTaskCreate: invalid conversion from 'void (*)()' to 'TaskFunction_t {aka void (*)(void*)}'

[azz-zza]

Hello,
i can not figure out what am i doing incorrectly here. Please advise.

Code: Select all

void publish_data() {
 ....
}


void setup () {
....
TaskHandle_t xHandle = NULL;
BaseType_t  xReturned = xTaskCreate(&publish_data, (const char*) "Task", 4048, 	(void*)	 1, NULL, &xHandle);
.....

src/main.cpp: In function 'void setup()':
src/main.cpp:125:109: error: invalid conversion from 'void (*)()' to 'TaskFunction_t {aka void (*)(void*)}' [-fpermissive]
   BaseType_t  xReturned = xTaskCreate(&publish_data, (const char*) "Task", 4048,  (void*)  1, NULL, &xHandle);

Code: Select all

void publish_data(void *you_need_this) {
 ....
}

ohhh.. (facepalm)....

Thank you so much.

and how do i call the createTask if i do not need any params passed to the procedure?

Use NULL (any other value will technically work as well, as your task ignores it anyway) instead of the parameter.

Thank you very much. Works perfectly.
The issue was not in the the xTaskCreate, but rather that callback procedure should have parameter.
