HAL_StatusTypeDef HAL_RTC_DeInit(RTC_HandleTypeDef *hrtc) function returns HAL_ERROR because RTC_EnterInitMode(hrtc) returns HAL_TIMEOUT. When checked in community, I can see solutions as to call HAL_PWR_EnableBkUpAccess(); before setting RTC functio...
I have a routine that self-calibrates a system and returns two uint16_t values that I need to write into non-volatile memory and read at bootup. The values will only be written once during production so write time isn't important. And it needs to be...
Hi,I'm porting a C++ application to a STM32, using CubeIDE. The application uses cin/cout, for which I implemented the __io_getchar() and __io_putchar() functions used by _read()/_write() from syscalls.c, redirecting the input/output to UART. This wo...
In my code, I write many casting from char* to uint64_t*. Someone success, and someone get failure. I thought I used the unallocated memory, but I rewrote by casting to uint32_t, and then no error happened. Is this normal?My code:--------------------...
Hello all,I recently purchased the STM32F469i Discovery Board, and have loaded the compiled demo binary from the ST website onto the board. It loads properly, but now I want to see how the software works. Is there any source code for the demo firmwar...
I'm using STM32F767 and external flash is interfaced on QUADSPI, I've referred STM32746G-Discovery code for QSPI without DMA and its working fine. I want to implement QSPI using DMA, STM32F767 supports QSPI over DMA on channel 3 and stream 7 so did c...
Hello everyone,I'm having problems with a STM32L010K8 in stop mode.I'm trying to use the low power timer clocked by the LSI and having it to wake up the device from stop mode once the timer reaches ARR value.I configured the EXTI event line 29 and de...
Can anyone share USB Host CDC VCP Example code for STM32F429 or STM32F469?
I want to know the ADC performance of STM32F103.I am not sure which datasheet to check.I know it is single ended in SAR ADC....I'd really appreciate it if you let me know.
Moin, is it possible to run the stm32L5 Series mcus (or other stm32s) not in SDMMC host mode, but be used like a normal SDcard for storage?I looked over the documentation and only found host mode descriptions. I feel like I missed some details, so gr...
