Question regarding Orangutan SVP-1284p LCD control lines

Is it possible to use LCD control lines PB0-PB2 as GPIO? I would like to connect QTR-1RC reflective sensors to these pins and use the commands in the PololuQTRSensors library.

Thank you

You should be able to use PB0 and PB2 as long as you physically remove the LCD and remove any lines of code from your program that try to use the LCD.

However, PB1 has a 4.7k pull-down resistor on it which will cause the capacitor to discharge faster than it normally would. So PB1 probably won’t work very well, but there is no harm in trying it.


Thank you I appreciate your help. :smiley:
