SPI slave mode transmission issue.
hi community,currently I am using the STM32H743zit6 board.My query related to the SPI slave mode.To test SPI master and slave mode I am configuring like this.SPI4 is used as Master it always receives data in full duplex mode and MISO is configured a...
Using a 32F469I-DISCOVERY board, is there any examples of creating a two output one-pulse timer with an external input? I am having trouble with the Arduino connector on the back of the board to pinout the three signals.
Also how to internally connect the input trigger to two simultaneous one-pulse generators.
STM32F4: SPI output using DMA with LL driver
HiI'm trying to get SPI output working using DMA with the LL drivers. I'm using CubeMX to set up the DMA and SPI and it works perfectly when I use HAL_SPI_Transmit_DMA to initiate the output. However, this is a very slow routine and I want to be able...
Troubleshooting reset causes using RCC->CSR register
I am trying to determine the cause of resets happening in my application. It does not seem like the RCC->CSR register is working properly.I tested this out by manually grounding the NRST pin and setting a break point in my code before main(). The CSR...
STM32H743: DMA constantly returns error HAL_DMA_ERROR_DME, no data transfer done.
Hello,I'm working on target STM32H743ZI.I would like to copy a memory buffer to the SAI interface (master).For some reason, when calling the function HAL_SAI_Transmit_DMA in the main, no transfer occurs. Going through more details, it seems that the ...
