PIC to LCD wiring problem ?

Please hold patience

please send a detail of what pins you have connected for the 10 wire cable clearly indicating cross connections of the pin numbers of 16 pin LCD display .

let us see, afterall the site gave so many photos to make me atleast feel that genuine effort was there.
Take little more pains

Connect buffered RC2(PIC-17) (that is resistor R7 at pin 10 of the pcb connctor JP1.) to pin 16 of the LCD

then youmay maintain 1V DC approx on pin3 ( contrast) some where beteen 0.9 to 1.2 the display will be clear.
All the best

Hi Pasan, please see the site below and some of the comments are extracted from there and pasted here. perhaps you have to use winpic or winpic800 for programming f877 where as f877A is programmable by ic-prog.

PIC16F870(8),PIC16F871(8),PIC16F872,PIC16F873,PIC16F874(4),PIC16F876(5),PIC16F877(5)
