Hi,
I am also facing the problem as Dileep had.I have used assembly code to program PIC16F877 which am attaching. When the power is on,lcd is showing black boxes in the 1st line.
1.Lcd 4-6 pins are connected to pin 2-4 of portc(Pc2-RS,Pc3-R/W,Pc4-EN)
2. Lcd 7-14 pins are connected to pin 0-7 of portd(data lines)
3. Lcd 1-3 pins are connected to potentiometer.
