Hello @SHebb.1 ,have u define the buffer correctly?For example, I resolved my problems in this way:static uint8_t __attribute__ ((section (".BDMA_Access"),used)) sbuffer_tx[2];static uint8_t __attribute__ ((section (".BDMA_Access"),used)) sbuffer_rx...
Hi @MHana.1 ,thanks for ur answer. Yes, my idea is to use SPI6 as a slave. However, I'm trying to debug ur sharing code, I noticed a very strange thing. Suppose to not connect anything to SPI6, and it is configurated likes ur code. If I debug HAL_S...
Hi MHana.1,I took a look at the code, i don't understand the presence of PG9 as external interrupt. Also, the togglepin PE5 which means?Do u have also test SPI6 as Slave?Thanks!!
Hello Deadbeef,I'm working to an SPI communication between two STM32H743 boards, in particular, for the first ST I use SPI3 (slave) with DMA and for the second ST I use SPI6 (slave) with BDMA. Both the boards are clocked with an external fixed clock....
