Hi
I have initialized the Micrium Rtos and there is no error when I compile the project but there is a OSTimeDly function in my code that is not working.
I should notify that when I give the first argument of this function ( related to number of ticks to specify the time delay ) the value of 0 , my task is working well but giving any value to this argument (500 in my code) , stops the program .
here is mu code :
Please help me to solve this problem.
Thanks in advance
