Hi!  I am working on a project where we are using DMA driven SPI-transmissions. I am using LPTIM1 to synchronize readouts of multiple SPI busses. The setup works when the transmissions is equal or below 128 bits (for SPI1-SPI3).  When HAL_DMA_MuxSync...
Hi!We are characterizing the ADC's in the STM32H7B3 µc. During temperature cycling of the HW we are observing some unexpected shifts in the conversion data from the ADC. The phenomena is observed across multiple HW units in varying degree. From one p...
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 8) table 4, it states t...
