touch sensing calibration

HiI'm working on touch sensing feature of stm32f051,,but I have a big problem that every board that I assembled has different thresholds for its sensors(the component are the same) and I can't have a unique code and each time I have to change thresho...

STM32 RTC Alarm behavior

I am currently making a device running the RTC calendar. The MCU will be in stop mode for the most of the time. It will wake up in the certain date and time. Is it possible to configure the STM32 to wake up once a month by setting the alarm day and t...

Which pins are available for CANFD2 on STM32H747I-DISCO board ?

Hi Community,I am using STM32H747I-DISCO board, I'd like to use 2 FDCAN but I can only find PA11 and PA12 on STMod+ connector for FDCAN1, seem like all of the FDCAN2 pins are not available but I'm not sure.Could you please help to find out ?By the wa...

how Multiple slave devices identification in software slave management works?

I am using STM32H7 family of microcontroller as SPI Master Transmit device which needs to talk to 4 SPI slave devices receive only which are also all STM32H7 MCU's. Both master and slave are configured for software slave management. The confusion is ...

why does the microcontroller lose the program when power is off?

How can I avoid this?

Applying voltage to output pins

Hi people.I have a circuit which must enables an LDO by pressing a button which applies 4.2~3.7V to EN pin of regulator. after enabling LDO, MCU (which is from F0 series) powers on and takes control of LDO EN pin by applying a HIGH output on EN pin w...
