I'm running an STM32L452RCTX uC, and I'm trying to implement a 2.5Vref+ ADC.Things weren't looking quite right on the pins I intend to implement, so for now I'm driving a floating TP with a power supply so I can directly test input vs output.When dri...

So I guess when you configure one channel, you don't configure them all ;)Thank you so much for that!At ground, measuring 0x000.At 3.3V, measuring 0xFFF.At the middle of a 1/2 resistor divider, 0x7FF.

@TDK:This is single-ended, and configured as such. I did post a screenshot of the ioc setup, I'll amend my original post with this information.I'll give it a shot, couldn't hurt. I *can* tell you I've compared my code to several of the sample proje...

Removing the LM4040 from the board yielded similar results.The ADC pin reads around 0x83A when floating, 0x7C0 when grounded, and 0xFB0 when 3.3V is applied.Calibration came out fine. Floating at 0x800s makes me think maybe an underflow resulting in...

HCLK is set for 80MHz, ADC settings are below:

I am having this issue on pins PC0, PC1, AND PA2, and my ioc file leads me to believe there are no conflicts as far as my setup (I'm aware hal can often do its own thing...).Aside from visually verifying the solder connections are excellent on both o...
