These are actually 16F88x'es, typically, although I probably will try to do the same with an 18F in a week or so... Just to update everyone, here's what I figured out: 1) The PicKit2 programmer will definately program a 16f88x running at 3.3V. Works great from MPLAB. 2) As a secondary bonus, I just discovered that the PicKit2 programmer software has this cool mode called "Auto Import Hex + Write Device". This allows you to select the .hex output file from your preferred C compiler/IDE, and whenever it is updated (aka recompiled) it will pick up the changes and re-write them to your target. This makes development really easy. Call me lazy, but I hate having to manually do something (power on/off, jumer, etc.) to get the target to run. I feel I've earned the right to be unhappy with having to touch the target after having had gone through the experience of developing numerous applications using an UV eprom eraser, eprom programmer, and a target without a ZIF socket. And I'm not just talking about PIC's here (think Z80). -forrest -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
