Hi there,
I've bought the Velleman programmer for learning PIC programming. I've successfully played w/ a PIC16F628A. Now I want to do something advanced and got myself a 16F877A. I've tried using the ICSP port on the programmer to connect to the PIC on a breadboard, but all I can read from it is 3FFF (except for the Device-ID that reads 3DCC). I'm unable to write anything.
I'm connecting the following way:
ICSP PIN -> PIC
1 - 1
2 - 11
3 - 12
4 - 40
5 - 39
I'm also shorting PIC PINs 11 to 32 and 12 to 31.
Can anyone please help me? Is there something missing? Is the oscilator needed to program it?
Thanks..
