I am using a number of Microchip PICs for some Model Railway projects. Currently I am using a QL200 Dev board for programing. I have had some problems recently when programming PIC12F629s in that they don't do what they are supposed to do. I have programmed the 629s for other projects to test the the QL200 and also the chip itself succesfully but they don't seem to work on the railway projects. I am sure that the hex programs supplied are correct if only from the feedback from the web sites from where I have got the designs.
Many replies have said that I should use a Microchip PICkit 2 for programming and I have now picked one up from a local charity shop but I think it is not complete. It consist of just a plastic case with a push switch, three lights marked Power, Target, Busy and a usb connection and a in-circuit connection (6 female)
Am I right in thinking that there should be a pcb with a socket/s for the various chips. Does anybody have a circuit design for such a board? Most, if not all of the circuits I use require a preprogrammed chip rather than programming in situ.
