STM32G474RE internal bootloader - cannot read Unique Device ID, Flash size and package reigsters with Read Memory command
Hi everybody,in my current project I use G474RE MCU and I wanted to use internal bootloader with the same tools which I've used with some previous projects and F401 MCU.I jump to internal bootloader with following code (ported from some official refe...
Hi, I was developing a USB-based datalogger with STM32L052K8 with the log in PDF format. Kindly let me know if we can accomplish the same with this STM32L052K8 MCU. Is there any pdf generating libraries for this?
The product is a temperature logger for use in the shipping industry. The controller will wake up in definite intervals and record the temperature reading and saves it in the memory. We need to store the data in PDF format for the end-user to downloa...
RTC stops during standby mode.
Hi, I'm using STM32L452, and i need to get the time and date from RTC. The RTC works fine, but when i enter in standby and check the time after wake up (via RTC), the RTC only incrment durring the waked time, and doesn't count the time durring standb...

Resolved! [BUG] STM32 HAL drivers are not interrupt-safe
In function HAL_DMA_IRQHandler() the lines 872, 914, 949 modify the hdma->State variable after __HAL_UNLOCK(hdma) has been called.STM32 HAL is full of bugs, especially race condition related ones, but this one seems to be more urgent, because multipl...

USBH_BulkReceiveData not working
Hello everybody,I am currently trying to implement a RTL2832 on STM32, the initialisation process works just fine (USBH_CtlReq). But during the USBH_RTLSDR_Process, my program first uses a USBH_BulkReceiveData and loops on USBH_LL_GetURBState. the st...
