Posted on August 07, 2017 at 16:34As the title says, the clock's wave is as below for DMA SPI2's Clock:My DMA SPI Setting is as below with red color: if(hspi->Instance==SPI2) { /* USER CODE BEGIN SPI2_MspInit 0 */ /* USER CODE END SPI2_MspInit 0 */ ...

Posted on August 08, 2017 at 09:01The right way to fix this issue is to disable NSSPMode as below:/* SPI2 init function */static void MX_SPI2_Init(void){hspi2.Instance = SPI2;hspi2.Init.Mode = SPI_MODE_MASTER;hspi2.Init.Direction = SPI_DIRECTION_2LI...

Posted on August 08, 2017 at 05:01I fix the issue by modifying SPI2's TIMode setting from:(disable -> enable)/* SPI2 init function */static void MX_SPI2_Init(void){hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MASTER; hspi2.Init.Direction = SPI_...

Posted on April 15, 2017 at 15:30if (HAL_ADC_Start_DMA(&hadc, (uint32_t*)ADC1ConvertedValues, 1024) != HAL_OK); 1024 is not correct, it should be 4 for you, I think.STM32F7xx HAL Library Descriped as below:/** * @brief Enables ADC DMA request after ...

Posted on April 15, 2017 at 15:23If you want to read multi-channel-adc, DMA Mode maybe the better way to do it, for example PC1 ------> ADC1_IN11, PC4 ------> ADC1_IN14, PA2 ------> ADC1_IN2, PC5 ------> ADC1_IN15 :1. ADC Initial : for channel wit...

Posted on April 15, 2017 at 12:54Use DMA Mode to read multi-channel-adc looks fine,for example PC1 ------> ADC1_IN11, PC4 ------> ADC1_IN14, PA2 ------> ADC1_IN2, PC5 ------> ADC1_IN15:1. ADC Initial : for channel with 4 different rank/* ADC1 init f...
