在STM32的UART（通用异步收发传输器）通信中，ErrorCode用于指示UART通信过程中发生的错误。这些错误码通常...
实现UART错误回调函数,处理HAL_UART_ERROR_ORE错误。 voidHAL_UART_ErrorCallback(UART_HandleTypeDef *huart) { if (huart->ErrorCode & HAL_UART_ERROR_ORE) {__HAL_UART_CLEAR_OREFLAG(huart);// 清除ORE错误标志// 重新启动DMA接收HAL_UART_Receive_DMA(huart, RxBuffer, sizeof(RxBuffer)); } } ...
FLAG()函数来清除标志位。例如，当检测到帧错误时，可以使用huart->ErrorCode |= HAL_UART_ERROR_FE...
