Hi forum! I need a delay in a programm but _nop_() seems not to work. Thus I wrote the following code in the main function where x is an IO pin: while(1) { x = 1; _nop_(); x = 0; _nop_(); } Only the second _nop_() causes a delay but not the first one. µVsioin2 is used. Can anybody help me? Thanks Fabian
I'm really sorry guys, but I still don't understand what I'm doing wrong. Tell us what you are trying to achieve. With the C166 CPU core (and even more so with the C166 v2 core) you cannot expect program execution time to be a simple arithmetic sum of execution times of each instruction because of things like CPU pipeline, jump cache and so on. By the way, what microcontroller are you using? Is it the older C16x family, or the newer XC16x family? Regards, - mike
