PICSTART Plus - In Circuit? - mippen2 - Nov 24 14:28:00 2003

Hello All! I have an "old" PICSTART Plus programmer and I would like to use it as an ICP.. Could I get some help with a simple schematic on the interface to make this work? I would like to fit it to a hardware that uses the ICD2 Programmer interface. /best regards Michael |

I have used the
picstart plus by simply putting a header on my board that connects the relevant pins for a
given processor, then take a socket for the processor and soldre the wires into the cups
and putting header on the end of the wires. Then you put the socket in the
programmer and connect the header to the board and it programs. The only thing to
watch out for is that one of the pins you have to connect is vdd and you don't want the
programmer to try to power your whole board so you may need to add a diode in
there.
Hope that
helps
Shawn

Hi ... and... if you power the target board with the PICSTART, it may go down the drain. It can't handle the current. I have however sucessfully powered the target, and then connected my PICSTART, and then programmed the PIC. Should work if the pins (often RB6 and RB7 - depends on PIC) are connected to soething hi-Z; that is, if the RB6 and 7 are outputs anyway. MCLR must also handle "abuse" from your PICSTART. /Sven > I have used the picstart plus by simply putting a header on my board that > connects the relevant pins for a given processor, then take a socket for > the > processor and soldre the wires into the cups and putting header on the end > of the wires.
