For example __CONFIG _CONFIG2L, _BOR_ON_2L & _BORV_45_2L & _PWRT_ON_2L not a number that has to be checked (possibly again and again) when something goes wrong or doesn't even work to begin with Entering binary and hex with switches and pushbuttons, which comparitively is how the OP say he programs, is so last century And the 18F6720 isn't a trivial PIC. If you're needing to use it, you mean business and need all the help you can get Sorry, I'm usually a bit more charitable than this, but c'mon -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
