I have set up a project with the STM32H7B3 where I want the LPTIM1 to generate a synchronization signal that triggers a DMA driven SPI trancieve of 6*11 bits. The SPI is set up with wordsize 11. The DMA for both rx and tx is set up in circular mode w...

Hi! I wonder if it is possible to set up the STM32H7B3 µC as a synchronous usart slave with the usart1 peripheral. From the reference manual it seems that it is only possible to set it up in 'SPI-mode'. The functionality I want is a USART slave that ...

Hi!I am looking into the possibility on using LPTIM1 to trigger a DMA transfer with no CPU interrupt. This timer is chosen because it can be clocked directly by the HSE clock input. In the datasheet of STM32H7B3 (DS13139 - Rev table 4, it states tha...
