4 x 20 LCD display with PB3 - Pin 5 High or Low?

[xpa999]

Thanks Darryl,

Silly question: Is there feedback from the display to the Lcdout routine (I'm thinking of the 4 bit communication) or is the pic blindly sending data to the LCD and relying on timing for the LCD to grab data?

Thanks again.

No, there is no feedback to the LCDOUT routines.

If the program stops or the chip resets when trying to display things, it could be that you have LVP enabled in the configs, and the LCD uses the PGM pin.
