#111870 - port0 pull up Responding to: ???'s previous message |
you need pull up resistors for port0 and don't forget the VC pin 3 on the LCD for contrast.
When you first power up your circuit, the top row of the LCD should be all black, once initialization of lcd is successful the LCD goes blank. Mahmood |
