  • Has anyone managed to get the PWM backlighting working with an Arduino? I’m trying variations of this and nothing works except the standard On/Off commands using 0xFE as the escape. All my attempts turn the display off but the backlight LED is on full.

    The splash screen on mine says SerLCD 2.5 so I believe my firmware is current. My board’s about 8 months old.

    void backlightLow() { //serCommand(); Serial.write(0x7C); Serial.write(140); }

    void backlightSet(int level) { Serial.write(0x7C); Serial.write(byte(level + 128)); }

No public wish lists :(
