simple 3 Button Touch Key application using TSC on STM32L431 goes wrong when VDD power supply drops from 3.3V to approx 3.0V (just above BOR level) then recovers to 3.3V.All 3 Buttons are read back as active from this point on. Has anybody experience...

is there a STM32W based BLE hardware module which is certified (FCC/EN)? We use a NINA-B112-00B based on Nordic Semiconductor right now and would like to replace it by an STM32W type with similar dimensions and certifications.

ADC high precision challenge

2019-07-18
Most 12bit ADCs of ST are specified not very accurate in DNL, INL, and total unadjusted Error. Especially DNL allows worst case scenarios of results being non-consecutive. I use these ADCs for several years now for slow signals and found ways in HW- ...
