ADC lines behavior when STM32 is not powered?
Hi!I'm using an ADC line of the STM32 MCU to read battery voltage that goes from 6.7V to 8.4V.The battery voltage is given to the MCU via a divider (by 4, so the maximum voltage given to the ADC line of the MCU will be 2.1V).I wanted to know, if ther...
Touch Key in STM32L1
Hello, We are currently working on touch sensing in STM32L1V8XA Microcontroller Below are the queries :1) How to get started with cap sense touch key in STM32L1V8XA Microcontroller. Do we need to use STMTouch touch-sensing library https://www.st.com/...

What is the best way to backup some bytes whitout RTC backup registers in order to enter in shutdown mode.
Hello, I use STM32L476 for very low power project. I also use an external RTC because it is temperature-compensated. My question is : What is the best way to backup some bytes whitout RTC backup registers in order to enter in shutdown mode.I had the ...
Datasheat vs .stm32h745xx.h
I am trying to debug my USB and in the process I am going through all the registers defined in the datasheet vs stm32h745xx.h file and I see that in some cases the .h file has registers defined that is not in the datasheetGUSBCFG_CTXPKT : in .h but n...
Resolved! This specific CAN2 config crashes during HAL_CAN_Init(), why
Lets hope someone has a felicitously revelation, or a clue.I am using a custom board with a nice stm32f105rbtx, fed with external XTAL.Everything worked like a charm untill i configured the clock to be 72Mhz and readjusted the can parameters in CUBEM...
