STM32 MCUs Products

STM32L151CBT6A MCU, Enter stop mode have biggest power consumption - above 960uA, but datasheet is ~2..10uA ? And MCU not wake up from STOP by RTC WKUP

Code of main cycle:// Some "works"... ipf("Works 5 sec\n\r"); HAL_Delay(5000);   // Prepare... ipf("Power save STOP mode 5 sec\n\r"); double CounterVal = 5000 * 2.3125; if (HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, (uint32_t)CounterVal, RTC_WAKEUPCLOCK_RTCC...

Have: STM32L151C8xxA Get VREFINT trouble (VREFINT voltage drifts depended on external power supply), how to get REAL input voltage?

Have you ever met a problem with HAL_MMC_ReadBlocks?

Hi,I'm working on SDMMC on STM32U5 nucleo board.Everything works fine for 1 and 4 bit mode.But, in 8 bit mode I can write data with HAL_MMC_WriteBlocks but when I try to read back with HAL_MMC_ReadBlocks, it always gets SDMMC_FLAG_DCRCFAIL.Have you e...

SD_FindSCR Function!?

My problem just like https://community.st.com/s/question/0D50X00009XkdhZ/sdfindscr-function-problem​In ​the SD_init function ,I use HAL_SD_ConfigWideBusOperation to change bus wide.​but sometime it will dead in SD_FindSCR => while(!__HAL_SD_GET_FLAG(...

DFU bootloader issues

I am trying to use the built-in bootloader in DFU mode on STM32H743IIT.1. I built my application and created a *.dfu file2. The bootloader starts fine and my device enumerates properly as "STM Device in DFU Mode"3. DfuSe Demo (v3.0.6) detects my devi...
