yes i found example code for some different stm mcu and crossed checked code with that both are same only but dont know that code is right or not cause i did not checked that as i dont have that MCU with me .
and ya i can transmit frame with every second but after transmission it is checking that anyfifo is free or not at that time i am getting ERROR . for receiving side also first it should check that any receivefifo is empty or not than it will receives data but in that function i am stucking i tried that also
