Hi,

I'm trying to program a PIC18LF2455 but never been successful on it..

I tried programming it on JDM2 using Win PIC, PICPgm but always ended in error...Even with GTP-USB 3.55g can't detect the chip but I can program all other PIC like 18F4550,877A,F84,F628A..I only got problem with this 18LF2455..

Can you recommend a working programmer (SERIAL or LPT) that works with 18LF2455?


TIA

Yes probably! but there is no listing of the CHIP itself.. Any by the by. There was an issue on PICKIT2 with LF chips but I cant remember where I saw it.
