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...
if ((HAL_IS_BIT_SET(huart->Instance->CR3, USART_CR3_DMAR)) || ((errorcode & (HAL_UART_...

一个奇怪的问题,使用STM32L432的UART通信,如果使能了uart的错误中断,代码如下:/* Enable the UART Error Interrupt: (Frame error, noise error, overrun error) */&nb ...
if(huart->ErrorCode & HAL_UART_ERROR_ORE)//溢出错误 { uint32_t temp = huart->Instance->SR; temp = huart->Instance->DR; } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 2.另外一种方法就是不使能接收中断,比如采用DMA+空闲中断的方式。可以参考之前的文章《STM32CubeMX之串口通信...
