LCD Block

4.3.12

Backlight Control

The LCD backlight is made of four integrated white chip-LEDs arranged in parallel. These are driven by 
an AAT3155 charge pump, MN8.The AAT3155 is controlled by the SAM4S through a single PIO line 
PC13 interface; the 0 Ohm resistor R68 is mounted in series on this line, which permits to use it for other 
custom purposes. In that case, the pull-up resistor R64 maintains the charge pump permanently enabled 
by default.

On the anode drive line, a 0 Ohm resistor R59 is implemented in series for an optional current limitation.
