Glcd backLight()

Sets the brightness of the LED backlight on the graphics board.

#include "GLCD_ST7565.h"
#include <Ports.h>
#include <RF12.h> // needed to avoid a linker error :(

GLCD_ST7565 glcd;
glcd.backLight(byte level);

Parameters

level

0-255.

Notes

This is the PWM value that will be written out of the interrupt pin so will only work if the jumper link on the graphics board has been connected to "I".
