Hello,
I need a right SPI configuration and Send_Receive_byte() funtion for using with STM32F4, STM32CubeMX 4.7.0 and HAL drivers... Does anyone have it?
I have a project running fine with STM32F4xx StdPeriph_Driver V1.2.0 to connect my STM32F4 and my L6482H chips. Now, I am trying to migrate my code, for using STM32 CubeMX v4.7.0 and HAL drivers. See below:void
HAL_SPI_MspInit
(SPI_HandleTypeDef* hspi) { GPIO_InitTypeDef GPIO_InitStruct; if(hspi->Instance==SPI1) { /* Peripheral clock enable */ __SPI1_CLK_ENABLE(); /**SPI1 GPIO Configuration PA5 ------> SPI1_SCK PA6 ------> SPI1_MISO PA7 ------> SPI1_MOSI */ GPIO_InitStruct.Pin = GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FAST; GPIO_InitStruct.Alternate = GPIO_AF5_SPI1; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct); /* System interrupt init*/ HAL_NVIC_SetPriority(SPI1_IRQn, 1, 0); HAL_NVIC_EnableIRQ(SPI1_IRQn); } } ----------------------------------------------------------/* SPI1 init function */
voidMX_SPI1_Init
(void) { hspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_MASTER; hspi1.Init.Direction = SPI_DIRECTION_2LINES; hspi1.Init.DataSize = SPI_DATASIZE_8BIT; hspi1.Init.CLKPolarity = SPI_POLARITY_HIGH; hspi1.Init.CLKPhase = SPI_PHASE_2EDGE; hspi1.Init.NSS = SPI_NSS_SOFT; hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_16; hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB; hspi1.Init.TIMode = SPI_TIMODE_DISABLED; hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_ENABLED; hspi1.Init.CRCPolynomial = 7; HAL_SPI_Init(&hspi1); } ----------------------------------------------------------uint8_t
CSPIN_Write_Byte
(SPI_HandleTypeDef *hspi, uint8_t byte) { // Check if SPI is running if((hspi->Instance->CR1 &SPI_CR1_SPE) != SPI_CR1_SPE) __HAL_SPI_ENABLE(&hspi1); /* nSS signal activation - low */ HAL_GPIO_WritePin(GPIOC, GPIO_PIN_5, GPIO_PIN_RESET); // SPI byte send. hspi->Instance->DR = byte; while (__HAL_SPI_GET_FLAG(&hspi1, SPI_FLAG_BSY) == true){}; // nSS signal deactivation - high HAL_GPIO_WritePin(GPIOC, GPIO_PIN_5, GPIO_PIN_SET); return (uint8_t)(hspi->Instance->DR); } -------------------------------------------------------But it doesnt work.
As you can see in pictures, the waveformsseem
correct
, but it does not work...With STM32F4xx StdPeriph_Driver V1.2.0
(it runs fine)With STM32CubeMX and HAL drivers
(It does not run, and MISO always returns 0x00)
