I use a STM32H723VGT6 as a master in a critical SPI communication with another microcontroller (critical because this mcu is very strict in the SPI timing, especially the time between CS and the start of CLK, and I cannot operate on the firmware of t...
Hi everybody,I'm sorry for poor English.I'm using STM32F407VET6 in my board and I set up watchdog timer. However sometimes microcontroller hangs . Here is the main loop of my code:while(TRUE) { // ====================================== ...
Hi everyoneIm still dealing with nand flash and im at the ecc part now :).I found a very good topic in ST but i still had questions and that topic was closed.https://community.st.com/s/question/0D50X00009XkZjD/nand-flash-fsmc-and-ecc?t=1637138511900T...
Good evening, I would need, for a project with a custom board that mounts a micro STM32H7A3... to be able to set the value of a pin to 0 or 1 during the code and not via MX cube for the initial settings which function could I use? I would like to poi...
Hi,Am trying to correctly connect to my external NOR flash memory using my STM32F446RE's DMA.Am not sure how to go about this and the libraries I have tried are not working at all.Here's a link to the library I tried to test the connectivity between ...
Hi,I would like to know if there are any resources for learning and understanding how to communicate (read/write/erase) from an external flash memory using SPI.I am using an STM32F446RE and my external flash memory is a w25q128.Ideally I would like t...
Hi,Just looking for confirmation that the FMC SDRAM controller supports bit swapping within byte lanes, and byte lane swapping (including the mask bit of course) on the STM32H745.We are implementing a 32-bit SDRAM interface, and I don't see any menti...
I'm reading a temperature sensor (TC77) via SPI, with the following code (using the old StdPeriph lib):int16_t hdw_tc77_getTempRegister(void) { int16_t tempRegister; /*TC77 TEMP register*/ SPI_InitTypeDef SPI_InitStructure; /*SPI confi...
Hello,I have problem in CAN2 STM32F4, that in mode Loopback working good, but when i change it to mode Normal not working (not transmission )Please do you have a solution for working in the mode Normal ?
