>> ICSP != ICD >> >> What is ICSP then? I was sure in the data sheet it said >> at least something about in circuit debugging next to ICSP. > >ICSP is In Circuit Serial Programming >ICD is In Circuit Debugging > >SImilar cable, similar functions... different things :-) And in PICs use the same pins, for both functions where a chip has ICD. But note that for some small chips, the normal chip has ICSP, but you can get a special chip (with extra pins, on an adapter) that can do ICD. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
