but the DMA receive buffer is always empty (all zeroes). In polled mode, everything works fine, but i must read one 16-bit sample value as 3x 8-bit SPI value and use a bit shifts. That is perhaps the problem. My sampling frequency is 48 kHz ...
目前,我只在 while(1) 之前启动 HAL_SPI_Receive_DMA,并在调用 USB_CDC_TX iujwers 2022-12-26 07:48:16 H743zit6使用SPIDMA模式接收数据异常怎么解决? }; HAL_SPI_Receive_DMA( hspi1,pData,128); while(HAL_SPI_GetState( hspi1) != HAL_SPI_STATE_READY); while 科源机电 2023-08-05 ...

HAL_SPI_Receive_DMA(&hspi2, receive_data, 5); void HAL_SPI_RxCpltCallback(SPI_HandleTypeDef *hspi) { printf("SPI Received! \n"); } void HAL_SPI_ErrorCallback(SPI_HandleTypeDef *hspi) { printf("TRANSFER_ERROR! \n"); } I am using CubeMX to setup F407 as shown belo...
there is huge amount of data to deal with. so the best practice will be spi dma. to configure the adc, i need to transmit 4bytes configuration data to the adc over spi. once the configuration is done. there is no need to transmit. after configuring the adc, i need to rece...
