Posted on February 24, 2013 at 09:08I have one strange problem. After this fragment of code program:b = a;a =/ 40;if(!a)//breakpointsthe results of two registers are: b = 50000 - good value, a=0The value of a should be about 1250 not 0!!I can't find...
Posted on February 28, 2013 at 09:31Good day, I configure PortB PB2, PB3 and PB4 as inputs, pull-up, no ext int. These pins work 100% no problem. I also configure PortC, PC0 and PC1 precisely the same as the above pins but the pull-ups is not connec...
