Unfortunately the command line support is missing in the PICkit 3, although there was/is an efford to make the 'new' PICkit 3 compatible with the PICkit 2. (as usualy, marketing decisions ... :) And the PICkit 2 can do all the debugging the PICkit 3 does plus it can work as UART and Logic Analyzer as well. > Having breakpoints and debug is a *good* thing. Depends, using breakpoints and/or debug on time critical stuff (like software PWM or UART) usually results in unexpected results, more often it is simpler to add one or more LEDs to display a state or do 'printf' style debugging via serial (UART/I2C/SPI). But as always, YMMV. best, Herbert > Bob > On May 25, 2013, at 9:44 PM, Herbert Poetzl <[email protected]> wrote: >> On Sat, May 25, 2013 at 08:46:03AM -0500, Jason Rabel wrote: >>> I've decided I finally want to tackle learning how to use a PIC >>> chip for some smaller projects.
