WebOct 8, 2024 · STM32 HAL SPI DMA multi read sensor. I would like to read out a sensor over SPI using the DMA. Since the sensor has some noise, I would like to take the average and so I need to read out the sensor several times. For this I decided to use the HAL_SPI_TransmitReceive_DMA () function, but it seems only to read out the sensor … Web主要用到硬件为SPI UART ...

WebStart a new STM32 project, select your board (I’m using a Nucleo-L476RG ), and give your project a memorable name. In the CubeMX tool, change the PA5 pin to Reset_State to disable it. This pin is connected to the LED on the Nucleo board. It's shared with the SPI SCK line, so we need to disable it before setting up SPI.
