I've been using MPLAB/MP-ICD for programming our latest product, which = uses a PIC16F877. This worked out fine as long as we were building a = dozen or two at a time. We are now building 500 at a time. I do not want = to spend the rest of my life enabling the watchdog timer, the brown out, = etc. What are you guys using for production in circuit serial = programming of PIC16f877's?
