We are using a LCD in combination with the MSP430.
A question popped up the other day about what the best practice would be in order to reduce the power consumption:
Either we can have logic to store the current state of the display and only partially update if we see that a change is necessary or we can alway write to all register all the time.
The question to you guys is:
Does it cost more to write the same state of the LCD to the register compared to having a code based LCD state checker?
I know this isn't a trivial question but maybe there is an approximate answer?
