Hi, I am trying to use STM32F103C8T6 standby mode and wake it up with wake up feature of RTC, but in CubeMX I don't see that this MCU would have wake up feature under RTC settings. How do I wake up this MCU from standby with RTC and wake up pin?

Hi, I have STM32F103 and STM32F411. I have successfully made HID mouse on STM32F103, but when I try to make the same on STM32F411, the mouse does not work: "(Code 43) A request for the USB device descriptor failed".What could be the problem?The code/...

Hi, I have STM32F407 and trying to read/wirte from/to SD card and often the code get stuck in the this loop: static uint32_t SD_FindSCR(SD_HandleTypeDef *hsd, uint32_t *pSCR) { //... while(!__HAL_SD_GET_FLAG(hsd, SDIO_FLAG_RXOVERR | SDIO_FLAG_DC...

Hi I have STM32F407 and after updating STM32CubeMX 6.6.1 -> 6.9.2 I faced the same issue with SD card:https://community.st.com/t5/stm32cubemx-mcus/sdcard-does-not-work-fr-not-ready-when-migrating-from-fw-f4-v1/m-p/115499#M3876It seems that with previ...

Hi, I want to use UART with DMA on my STM32F407 MCU. I would expect that it would trigger `HAL_UART_TxCpltCallback` interrupt on transfer complete, but it does not do that. I tried many different configurations in STM32CubeMX:enabling "USART2 global ...

The issue was in wrong clock configuration. Oscillator value 16Mhz instead of 25Mhz.

Nevermind... It seems that I set wrong oscillator value... 16Mhz instead of 25Mhz! Now mouse example is working!

I don't think I have changed anything manually. Everything should be kept as default after generating the project with CubeMX.

It seems I had this error, because of bad power supply. Attached too many things to power supply and this started happening. It seems to be fixed!
