> Means I can't afford a PIC programmer yet *sob*. (Note: I would build one, but I haven't found any that are quoted to work with a 16F877, what I hope to use in the long-run). Did you really look around? Check my http://www.voti.nl/wisp628 (~ $28 for a kit, I will set up a 'shop' page next week, but the full design is also available for DIY): The following target chips are currently supported: 16c84, 16f84, 16f84a 16f627 (untested), 16f628 16f73, 16f74, 16f76, 16f77 16f870, 16f871, 16f872, 16f873, 16f874, 16f876, 16f877 (I am working on 18F's, and 16f87xA's will be added soon) And I seriously can not imagine that this is the only one.... BTW if you want 16f877 you could buy the chip programmed with a bootloader: no programmer needed, just a max232. See www.voti.nl/wloader , I sell the programmed chip, but the full details are also avaialbel for DIY. And I am sure I am not the only that does.
