I need the ASM codes to activate the charger light and turn the LCD off.
1) Please write more descriptive topic titles
2) Please post in the correct subforum. This is the Graphics subforum, and you're asking a z80 assembly question.
3) Please tell us what you've already tried and where you've already looked to answer this question yourself.
The charger LED is controlled directly by the battery charge controller chip and cannot be toggled in software. The LCD backlight can be easily controlled, but the LCD itself has a separate controller (which itself draws a small but non-negligible current) and turning that on and off is much more conplicated.


Code:
BacklightOff:
 in a, (3Ah)
 and (20h)
 out (3Ah), a
 ret

BacklightOn:
 b_call(_BacklightPowerOnInit)
