In reading the manuals and datasheets, it seems like it should be possible to simultaneously use all 3 channels (DAC1 Channel 1, DAC1 Channel 2, and DAC2 Channel 1) of the onboard DACs at once, emitting separate values on each. However, no matter wha...

Thanks for the advice, Dave! It's entirely possible this is correct, and might help to explain why the inspected registers all read 0 despite each of the methods returning HAL_OK. Unfortunately I'll have to do some research on how I might modify or o...

Yeah, it's quite perplexing, I'd assumed maybe the pin was dead or there was a short, but clearly that's not the case. My best guess, given I checked the SFRs and there only appear to be two total registers for the DACs, is that only two of them can ...

These autogenerated functions are both being called:MX_DAC1_Init(); MX_DAC2_Init();The DAC channels are manually started as so:HAL_DAC_Start(&hdac1, DAC_CHANNEL_1); HAL_DAC_Start(&hdac1, DAC_CHANNEL_2); HAL_DAC_Start(&hdac2, DAC_CHANNEL_1);Each is se...

The pin does toggle on and off (0V and 3V3, as expected). Here's the register values after initializing and starting DAC2, then setting a value:Name : Instance (hdac2) Details:0x58003400 Name : CR Details:0 Name : SWTRIGR Details:0 Name : DH...
