Okay, what am I doing wrong?! I've got an Olimex PG-2C. I place a PIC16F628 in the programmer socket and it programs and verifies just fine, using IC-Prog v1.05. When I connect the ICSP lines to the PIC and try programming it fails. Pin 1 of ICSP (Vpp) is connected to

All the examples I've seen for ICSP use a MAX232, but the PICAXE 18X, which is a PIC16F88, has a simple two-resistor serial interface. Any reasons why I can't use the resistor interface for PIC ICSP? Mike

Hello, I want to bring in attention an old subject but in another light. I use JDM programmer as a PIC serial programmer. I read that it supports ICSP but I'm not sure. My question is what is a good programmer on the web with all those : - can be build home (no pr

Does anyone know if a rfPIC can be programmed with an inexpensive programmer (and by inexpensive I mean under 200USD)? It looks like ICD2 won't do it nor will a PicStart. I own a Warp-13A and have had luck using it for ICSP on the couple of chips I've programmed. Ideally I

Hello, I'm working on PIC programmer and I need advice. After spending one day on Internet checking all of the existing solutions both hardware and software, and one additional day to read all of those ICSP Manuals from Microchip, and another day to evaluate signals fro

Guys need your help I have a cheap commercial PIC programmer based on the JMD design. It works fine, but I have subsequently found that it will not program 18F2550 PICs via ICSP, but will work fine when the PIC is placed in the sockets on the programmer. A friend therefore suggested that I use a bootloader which will make for rapid loading and testing of the development code I'm wor...
