Hello everyone, I am trying to use the PSSI peripheral with DMA on my nucleo-H7S3L8, I am new to this GPDMA so at first i tried using the standard request mode and i got it working but it only receives once and stops do i need to manually enable it a...
Hi everyone,we're using the STM34F407ZG microcontroller in our BMS board.We have some issue during contact 8kV ESD applied in some screws above the boards. The ESD are applyed on all the screws but the problematic one are just 3 screws, the closest s...
Hi there,this is an general question.Every serious engineer walks thru errata document as it gets published.So do I now.Do I have to review every HAL / LL function which may coincide with erratic behaviour?Is proposed in errata workaround already imp...
Hi, erasing a complete page (2KB) to just write a few bytes is a waste of erase/write cycle. Is there a way to write data in differents part of the page each time? when there is no more space then a page erase should be fired and start over. Is there...
Hi,I use STM32F103C8T6 a GPIO input pin to read a high or low signal from another GPIO output pin, and connect a 3Mohm resistor between two pins, and I notice touching GND with hand will influence the signal status, than I measure the resistance betw...
We are having an issue of the MCU bricking when we change the n_SWAP_Bank bit of the User Option bytes. What could be the issue? The issue occurs when we are clearing this bit. Once we clear it the chip bricks.
Hi,I am trying to configure an input capture on my STM32F051R8Tx. It works fine, I am supplying an external signal via a signal generator and my code measures exactly T=4ms pulses - which I expect. In my case, I am sampling with 24MHz, so the measure...
Hello,I'm working on project with STM32H755ZIT6. Currently I use Nucleo Board, but I designed prototype board, but the board don't work. I supose that problem is caused by wrong connection for supply.I use +3.3V from DC/DC connerter for suplly. Can s...
When switching on a new, unprogrammed STM32L431, PA6 turns hard to output high.This is SPI1 MOSI.AN2606 should say this out aloud.I know the 'G0 have this too, and AN2606 says this for them, although quite quietly and confusingly in a footnote.There ...
Hello, i am trying to use SPI2 on STM32H753VIT6 MCU using PD3 as Clock and PC2_C as MISO. Using the Hal libraries, i can generate clock on PD3 pin, and sensor answers me. But i dont get the sensor value on my software. Strange behaviour is, at its no...
