pg2c programmer and external power supply - a_drunken_dwarf - Nov 19 21:21:00 2003

hi, I'm using a pg2c programmer (by olimex). I works well if the PIC is in the programmer socket, but my laptop serial port can't supply enough power to do ICSP. If I want to provide external power during ICSP programming, would I just disconnect the programmer's ICSP power lines from the PIC, and instead supply a regulated 5V to the VDD pin and GND at VSS? Does anybody with a pg2c have any advice? thanks! |

Why not ping Olimex on it? They usually answer questions and would know if it was possible. DLC a_drunken_dwarf wrote: > hi, I'm using a pg2c programmer (by olimex).

Consider a MAX232 to 'pep-up' the RS-232 signal strength?

max232, good point. But I should use a regulated +5V through the max232 right? Or does the PIC need higher voltages during programming? --- In , "Wouter van Ooijen" <wouter@v...> wrote: > > hi, I'm using a pg2c programmer (by olimex).

Or wouldn't a ULN2803 work better? a ULN2803 amplifies current.

What I meant with the max232 is that you can use it (or maybe two of them) to make any RS-232 port behave. It will not add ICSP capability to a programmer design that does not have this capability in the first place.
