I currently use the NOPPP circuit to program 16f84's. I got a schematic for the P16PRO and have most of the parts here already but in looking at the schematic, R9 is listed as 680E. What does this mean?? I am new to this and have so far been able to light LED's and scan a keypad. Learning all I can. Hopefully, this leads to being able to design more useful ciruits. This Listserve has been most helpful in all of the other qeustions I have had so far and I thank you all for lending your time and expertise. Thanks in advance, Joe

What does this > mean?? It means you've got a *funny version* of the schematic. My schematic for P16PRO has only resistors R1 to R7! Perhaps you'd better quote a website for this schematic? -- Cheers, Paul B.

You have downloaded the PDF version of the P16PRO40 from http://www.geocities.com/SiliconValley/Peaks/9620/. That schematic has an error - there are two resistors labeled R9. I purchased a kit from Amazing Electronics, and they refer to R9 as the 4.7K resistor by TR3, and R11 is a 680 Ohm. --- Greetings to All! I'm a new member here, and the only thing I've burned onto a PIC is a "blinking LED" using the aforementioned P16PRO40. My dayjob is software programming using anything from C to VB or FoxPro, and I have some 6502 and misc. assembler experience. I've done a bit of electronics construction, etc. For example, I bought a bare ASM-1 PCB for an analog synthesizer, purchased parts, soldered them in, wired up a front panel with 25+ pots and 15+ jacks and it worked!
