Resolved! TSC measurement after exiting STOP mode (Abnormal delta)

Hi,MCU: STM32L072MCU is using TSC and ST touch sense library. When there is no stop mode involved, the measurement delta of no pressing is normal (-1, 0, 1).If MCU enters stop mode and then exits stop mode for touch sensing measurement, the delta wou...

Resolved! Minimum pulse width for STM32F2 timer in input capture mode.

I have a low frequency (~1 kHz), low duty cycle signal that I'd like to capture rising edges of. What's the minimum width of those pulses to capture them using a timer in input capture mode?I see there's a programmable digital filter there, in terms...

Resolved! Why is does the ADC stay on 2048 (12Bit)?

Hello Our STM32G4 is measuring a sinus-ADC value with offset. The offset is at VDDA/2.Our ADC measurement shows a plateau at the offset, even, when the sinus signal is crossing the VDDA/2 (see attached picture).The signal them self seems to be ok (me...
