SAMD21 DAC events and TCx @smerrett79 Did you ever manage to get the DAC and TC5 to play nice together? I'm having similar troubles on the SAM L21 over here https://community.atmel.com/forum/...
SAM L21 DAC0 and refresh I'm playing with a SAM L21 Xplained Pro right now, and refresh on DAC0 seems to be working. Before I set DATA0, I see drift like you described, but after doing the...

Stepping artifact on SAM L21 DAC transitions I notice the datasheet gives the conversion time 12 x 2 x TGCLK, so if TGCLK is 4MHz that should yield a 6us settling time, right? Looks more like 15us above...
DISKIO for SAM L21 Thanks for the response. If it's not available, shouldn't they filter the DISKIO component out of the list so it can't be selected?

@ paul.gaastra Did you ever get an answer to your original question? It definitely isn't due to any sort of plugin or source control. I have a vanilla...
