M0 Watchdog timer
« on: September 23, 2021, 12:37:19 PM »
Is there a watchdog timer for M0. I am putting the uC to sleep and wake up once a minute to take a reading from the BME 280, but very randomly the uC will hang at wakeup time.

My take would be to fix the issue rather than apply a bandaid, but see this article about WDT on SAMD21:
