But there are many other ways to "debug" all the way from proof-reading the code through add some debug-code (blink a LED or something) to full-blown in-circuit-debuging.

I guess there are many out there without a PIC16F648A-ICD but still writing real code for the PIC16F628A. > Or do you use another method to check your code before programming? > - Proof-read. - Use MPSIM. - Work with isolated parts of teh code at a time. - Write test-cases for parts of the code you're not sure about. - Test it by actualy programming it and see what happens. > Thanks > L. > --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
