Post by thread:OS/2, fast Pentium, and David Tait's PIC16C84 prog

Is there someone having experiences * using ultra-cheap programmers (like David Tait's, Henk Schaer's or LUDIPIPO) * on FAST PC's (P133...) * under OS/2 WARP I already *KNOW* David's PIC84FAQ and some hints he gave there, and the various delays in the PP.C program varieties, and I have seen once a programmer circuit layout showing an additional 555-Timer to produce an independent timing (Steve Marchant July 96). The use of a small timing source on the programmer sounds to me like a good idea. Why not using one "extra" PIC for managing the programming ? Any experiences ? Of course, I am aware of the multi-tasking environment. * So, is there anyone having a kind of "PIC84 for OS2", preferably in C (for example using the emx compiler) and with a reliable timing resource on that programmer ?

The 555 is used in a voltage doubler circuit, to get over the problem with some serial ports of a low voltage, insufficient to meet the PIC's programming spec. It's nothing to do with the timing.
