My project uses an atmega168p and a standard LCD 16x2.
In power down mode the avr takes less than 1µA but the LCD chipset takes about 1.5mA, always.
So my question is, can I power the LCD chipset with a pin of the AVR? So before going into sleep mode I could drive the pin low to shutdown the LCD controller?
I know it looks strange to power a chipset with an output pin :oops: ...
