Hi to all CC5x users. I have a small question for you concerning the Microchip ICD debugger: In the CC5x manual section 1.6 'defining the PICmicro device' there is a note that says "ICD debugging requires defining a symbol first" And the manual also says that one way of doing this is '#define ICD_DEBUG' Now, I've never done this in my program listing, but the ICD seems to work OK. Does the fact that I have already set the Development Mode in MPLAB to 16f877-ICD avoid the need for the above definition, or am I storing up trouble for myself?
