(Sorry for the mismatched part number. I wasn't getting any results when searching for the MSP432P401R.)
Hello,
I was wondering if there was any way that I could disable the +5 and +3.3V output pins on the MSP432P401R boards.
I am working on a wireless IoT solution which requires saving as much power as possible. I currently have a signal conditioning board being powered by the +5V pin of the 432 and an accelerometer being powered by the +3.3V pin. I noticed when the MSP432 enters LPM3.5 that these pins are still powering everything. I have been using the MSP432 SDK for things like Timer32 and LPM, but I haven't had any luck finding software solutions in the SDK for this problem. However, I'm fairly new to development on the 432s, and I acknowledge that I might be misunderstanding this problem entirely.
Any suggestions for software or hardware solutions would be helpful.
Thanks,
Greg
