Hi!In version 4 of the reference manual for STM32U0, it is suggested that BOR is enabled and on Level 3 from the factory.Is that correct?I'm currently working on an construction running @ 2V, so it would never start up, if so. And when I read out the...
Hello,I am currently reviewing a hardware design based on the STM32H563ZIT6 and have some questions regarding the internal and external behavior of the NRST pin.My main question is how the NRST pin operates specifically during an NVIC_SystemReset.Cur...
I need to create a UART driver that works reliably in all conditions.The driver must use DMA, and since the incoming messages are NOT fixed-length, I need to use idle line detection.My question is: how can I use a callback to store the received mess...
I am working on STM32h747 series. I am debugging both CM4 and CM7. After a while, CM4 stops responding and the debug messages shows:"Error in final launch sequence: Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK dev...
Could you please help me find out how much internal storage space this model STM32F427VIT6 has? Thanks a lot.
ST moderator: Edited the tile to add "ADC" I want to extract data at high sampling frequency ~10KHz at STM32N6570-DK, Is it possible with USART for three channels or we have any other mode for this purpose. I want to continuously stream data at 10KHz...
We are currently working on a project using the STM32H750IBT6 microcontroller interfaced with a single-bank Quad SPI NOR Flash (MT25QL512ABB) on our custom board. The QSPI interface is operational.However, we are facing an issue with the external loa...
I am currently using an STM32L011F4U6 to communicate with some other chips and it is failing to pull either I2C line down to GND fully when signalling, they are seemingly clamped to approximately 1.2V at a minimum as shown below making it impossible ...
Code is written using stm32CubeMX. Connecting with stmlink V3 Minie. Executing step by step, it appears that debug fails (lose connection) when executing debug_init. In fact debug_init creates the problem when programming pa13.When removing the initi...
Hello,I have an STM32G441 and using DMA to transmit some SPI data. All works so far. The problem is the chipselect. I am using the software chipselect. So before I start the DMA I pull CS low. Then when the DMA complete interrupt fires I pull it high...
