Latest non-beta (7.50) > - You use this circuit and it does not do the job? No, there is no circuit. The 10F is connected to the PS+ by short wires I think the problem is that it needs an adapter. I foolishly assumed that an 8-pin DIP 10F could be placed into the ZIF and programmed, and therefore translating those pin functions onto an SOT23 would work According to the PS+ Release Notes, thereby onto http://ww1.microchip.com/downloads/en/DeviceDoc/51491A.pdf (I won't bore you with the 2 hours of frustration with that pile of junk Microchip call a Search Engine. Suffice it to say I finally figured out sometimes it's quicker to Google to find Microchip documents. Pathetic) the adapter shifts the pin assignments around. So what I really need to know is what pins on the PS+ ZIF are used to program a 10F Although the above describes a 6-pin connector, I have no idea where these pins go via the adapter. Mention is made of 18-pins and aligning pin1 to pin9. I can't find a picture or schematic of it to explain that It is said to be included on the PicKit CD, so if anyone cares to share I'd be most grateful Now I think I'll go and have some Aspirin on toast ...... -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
