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

Hi all, I've been trying to figure the best way to connect pins for ISCP for a couple chips. 16F877 (40 pin) 16F873 (28 pin) and the 16F628(18 pin) one thing that seems to be really consistant is the lack of consistance of which pins on a ICSP header are which. Can anyone offer some guidance ? I'm pretty tempted to use the Olimex

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

Hi, I'm trying to use a standard LCD (16x2) to display a reading from a sharp gp2d120 distance sensor but having poor luck. The LCD works great but when I plug the sensor to the circuit the screen either hangs up or displays nothing or nonsens. I also noticed that programming the pic (via ICSP) fails while the sensor is connected. I'm aware that the

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...
