Resuming STOP Mode in STM32L152

Hi All,I've implemented STOP mode with the following code: (Taken from https://www.digikey.com/eewiki/display/microcontroller/Low-Power+Modes+on+the+STM32L0+Series)void EnterSTOP(void) { PWR->CR |= PWR_CR_CWUF; // clear the WUF flag after 2 clock ...

hi, folks, I am using stm32f429 development board. I am trying to upload the USB otg fs cube code for arm Keil, but I didn't get the USB comport on my desktop. I don't know what's issue here, so kindly help me out

any MCU (esp32 in my case) -> QSPI -> STM32F746 -> LCD glass

I am a bit confused with this setup but hopefully someone can enlighten me with the correct approach, I have an MCU based system and I need an LCD, unfortunately, it needs TFT controller thats why I add STM32F746 in the middle. hope someone can corre...

STM32F3 enabling timer from comparator output

Hi,I am enabling timer at comparators interrupt but i am having some timing issues. I think it can solve this timing issues if I can enable the timer as hardware. In reference manual i couldn't find any way for do that.Is there any way to do that ?T...

Is it possible to use the capture compare function to interrupt on an encoder value?

Based on the documentation it seems unlikely. However this also seems like an obvious use-case.Are there any examples doing this?Thanks

How do you design board support drivers?

I have got to implement a board support package for a custom board, and I would like to know your opinion about the different approaches of designing board support drivers. My custom board pupulates an STM32 microcontroller besides other components l...

RTC_HOURFORMAT_24 does not work in L053.

My environment is as follows:CubeMX v4.26.1 with STM32L0 HAL v1.10.0STM32L053C8Txgcc-arm-none-eabi-7-2017--q4-majorI set the RTC with RTC_HOURFORMAT_24. Actual code for the setup was generated by the CubeMX. If I set the clock to 12:59:59 then the R...
