hello,

I'm not able to program a pic 16f877a. The pic circuit and the programmer worked when i used picprog. now i have switched to win 7 and picpgm but the pic is not detected.

the programmer is a an589 homebrew and picpgm detected it as 589 programmer.

i have tried to modify Timing Delay factor to 8 and the pic is detected but as a 16f1937 instead of 16f877a !!

which i the reason the PIC detected is wrong?

At the moment i cannot program the PIC, I have tried a second one 16f877a but with the same result.
