Last edited by FvM; 2nd December at In your example, this would take 3 seconds because 3 of the 9 numbers in “a” are multples of 3. So, I need to write only numbers every second in string on display memory mapped on 0x adress which are divding with 3.

Input port and input output port declaration in top module 2. Below is code which i imagine but dont work correctly The interrupt routine posted above is designed to delay 1 second for each “multiple of three” number.

Does it write the string of all the even numbers once per second? Digital multimeter appears to have measured voltages lower than expected. Dec 248: AF programing in Transmitter what is the A? See if these changes to the interrupt routine help with the timing.
