jpnorair 340 Posted April 15, 2015 I posted a blog entry about how I used the STM32L1 RTC (a few years ago) as a tickless, ultra-low-power timer for my RTOS. http://www.indigresso.com/_blog/?p=181 The MSP432 has a similar problem. Only the RTC and Watchdogs run in LPM3 and 3.5, no other timers do, but you want to use those LPMs for timed sleep! There is a workaround, and it is actually very fast thanks to the really great ALU in the CM3 and CM4 devices. My code is also implemented in bulletproof production firmware that I've shipped to various industries . Yes, the code is for STM32L1, but I think you should be able to very easily port it to MSP432. If you wait long enough, I already will have ported it, but I noticed some forum activity on this very topic last week and I had to step in. Happy Coding. 4 tripwire, JasonP, congia and 1 other reacted to this Share this post Link to post Share on other sites
JasonP 5 Posted April 7, 2016 Hello @@jpnorair, Has there been any work done porting this over to MSP432? This is one of the pieces (a low power timer interrupt) needed for a project I am working on. If so, do you mind sharing? Thanks! Share this post Link to post Share on other sites
