Hi, Olin, in my last threat you mentioned: =20 ME: My ICSP hardware is a PICStart+ (I love it!) YOU: That's a development, not production programmer according to Microchip's own classification. It's OK to use for programming one off versions for testing and debugging, but you really shouldn't be using it in production. What is the difference between production / development programmers? Are timings somewhat incorrct? Voltages incorrect? As far as I understood there is a specification how to flash a PIC, so every programmer should follow these specs. Pls let me take part in your experience.
