MSP430FG437 in LPM3, but keep the LCD ON?

Other Parts Discussed in Thread: MSP430FG437

Hello:

I am looking for example codes that keep the LCD ON, while the MSP430FG437 is in LPM3 mode etc.

Do TI have example codes that put MSP430FG437 into LPM3, LPM2, LPM1, LPM0, and keep the LCD ON?

Thank You

Mike

    Since some of the LPMs switch the clocks off (to drop the power consumption) and the LCD requires them on, this is mutually exclusive.

    However, most LPMs shouldn't affect the LCD at all. So you don't need an example for how to keep the LCD on, you only have to remove the line that switches the LCD off before entering LPM in the example you have.

    After all, entering LPMs doesn't mean 'I want to waste less power', it means 'I deactivate some things so the system requires less power'. You cannot deactivate and still use things and get functionality without paying the current.
