I have a STM32F373VBTx serie. I know that the RTC saves the backup registers for every second. But when I restart my STM32, then the RTC sets to default date and time again due to the MX_RTC_INIT() function who is generated by CubeMX.I have two quest...
HiOur chipset is STM32G491CE.I use DAC with DMA in circular mode. DAC stop and restart. It is started previous array index.I want to be clear DMA circular buffer index.How can i do it?

When using LL libraries i include:DEBUGUSE_FULL_LL_DRIVERSSTM32F411xEDo i have to add something for HAL?Thanks
I am using stm32cubeide to program a stm32f030f4p6 MC. I have assigned one pin as an external interrupt and it is connected to the data output of an RF433 receiver. Here is a summary of my code:int k; int main(void) { while (1) { k=0; ...
The goal is to have the microcontroller which is in sleep mode, wake up when the voltage on a certain ADC channel drop below a set voltage.The plan was to put the core to sleep via HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI)...
Hi,I am new to QSPI. I working with stm32f469 disco that comes with external flash N25Q128A13EF840F. I had done the GUI part now I need to store data to external flash but I don't know how to do it. I had initialized qspi with STMCUBE default initial...
Hello,I would like to know, why unconfigured pin is consuming power when it is connected to 3.3 volt, while it is in analog input mode (reset mode as per to the data sheet). here, what i have tested with three configurations.with pin configuration(PA...
We are using the STM32L4A6 in a new project. This has the QSPI peripheral that supports two 4-bit banks. The datasheet and app notes only mention using the two banks together to give an 8 bit interface, but I'm wondering, is there any way to use them...
/*UPDATE*/ It turned out that im my case the problem was in the start up routine:There was a "Start up" project (written not by me) that was downloaded at 0 flash address and it was jumping to another address where my project was located.I did not kn...
