Hi all, I just stopped by to check if my experiences are right… 1 In my mios c program (user\_tick function) i used a modulo division like counter%divider and divider was a unsigned, non zero value, which caused the program to crash and the pic to start over. Using a number did’t. I could think of workarounds, but I am curious to hear yours 2 the same happened with 3 nested ifs, again I am working on a workaround, but I am equally happy to hear yours. Is there a list of Mios8 don’t in C programming?
