Within a test project like rtos_basic, look at:
-the class Thread :you find the function set_priority
-in rtx/cmsi_os.h you find the definition of priority (line 154)
I hope this can help you

thank you for the fast respons, I will look into it.
update: I got it working using the rtos_basic program with some code from this program: https://mbed.org/users/JimCarver/code/KL46_eCompass/file/ba1dbfb683fb/main.cpp
setting and printing priority in RTOS
#include "mbed.h" #include "rtos.h" DigitalOut led1(LED1); DigitalOut led2(LED2); Serial pc(USBTX, USBRX); // tx, rx Thread *(test); void led2_thread(void const *args) { while (true) { led2 = !led2; Thread::wait(1000); } } int main() { Thread thread(led2_thread); test = &thread; test->set_priority(osPriorityHigh); pc.printf("%i\n\r",test->get_priority()); while (true) { led1 = !led1; Thread::wait(500); } }
The program sends a 2 to the serial program on my computer confirming that the priority is set high.
