New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

Resolved! simple 3 Button Touch Key application using TSC on STM32L431 goes wrong when power supply drops from 3.3V to approx 3.0V then recovers to 3.3V.

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...

SAI_DMA_ERROR while using Receive_IT()

Dear Community,i'm working on an 4 Slot SAI Interface with an STM32G4 Series MCU. The FrameSync signal is kind of slow (~2kHz) so i want to use the Receive_IT() to throw an interrupt when 4 Slots (32Bit each) has received. So after starting the ADC H...

Encoder mode counter division possibilities?

Now every rising and fall edge are counted which results in counter incrementing by 4. I see and have tried playing with Prescaler Division Ratio which should normally be the parameter to divide incremental number but it does not work on Encoder mode...
