Template description: Software GPIO scan 3V 1/2Bias 1/4Duty of two LCD display example. Through the GPIO control input LCD voltage, in the timer interrupt to complete the IO scan, LED display timing. To use this demo, you need to connect two voltage divider resistors at the top and bottom of the COM port of LCD, one side of the two resistors is connected to VDD or GPIO control, and the other side is connected to GND, the two resistors are of equal resistance.
