Good Morning,
the project is based on a (fairly old) cube-mx template.
in main.c, i do
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_DMA_Init();
MX_CRC_Init();
MX_RNG_Init();
MX_FMC_Init();
MX_SPI3_Init();
MX_USART1_UART_Init();
[...]
HAL_UART_DeInit(&huart1);
[...]
di.huartX = &huart1;
di.huartX->Init.WordLength = UART_WORDLENGTH_8B;
di.huartX->Init.Parity = UART_PARITY_NONE;
di.huartX->Init.StopBits = UART_STOPBITS_1;
di.huartX->Instance = USART1;
HAL_USART_Init((USART_HandleTypeDef*)deviceInfo.huartX);
[...]
di.huartX->Init.BaudRate = deviceInfo.baudrate;
HAL_UART_Init(deviceInfo.huartX);
usart.c is expanded by the interrupt commands:
void MX_USART1_UART_Init(void)
{
huart1.Instance = USART1;
huart1.Init.BaudRate = ESO_DEFAULT_BAUDRATE;
huart1.Init.WordLength = UART_WORDLENGTH_9B;
huart1.Init.StopBits = UART_STOPBITS_1;
huart1.Init.Parity = UART_PARITY_EVEN;
huart1.Init.Mode = UART_MODE_TX_RX;
huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart1.Init.OverSampling = UART_OVERSAMPLING_8;
#ifdef BOOTLOAD
HAL_NVIC_SetPriority(USART1_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(USART1_IRQn);
#endif
if (HAL_UART_Init(&huart1) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
}
The Send-Receive is then performed as:
HAL_UART_Transmit(di.huartX, buffer->packet.array, buffer->length, 500);
di.huartX->Instance->DR; // necessary to clear last byte so it doesn't show up at the beginning of new buffer...
HAL_UART_Receive_DMA(di.huartX, buffer->next->packet.array, 259);
