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。这些错误码通常定义在STM32 HAL（硬件抽象层）库中，以便用户能够方便地识别和处理各种通信错误。以下是一些常见的STM32 UART ErrorCode及其描述：HAL_UART_ERROR_NONE：描述：无错误。值：通常定义为0x00
huart->ErrorCode = HAL_UART_ERROR_NONE; huart->gState = HAL_UART_STATE_BUSY_TX;/* Process Unlocked */__HAL_UNLOCK(huart);/* Enable the UART Transmit data register empty Interrupt */__HAL_UART_ENABLE_IT(huart, UART_IT_TXE);returnHAL_OK; }else{returnHAL_BUSY; } } 此外我们还会...

return HAL_ERROR; } /* Process Locked */ __HAL_LOCK(huart); huart->pTxBuffPtr = pData; huart->TxXferSize = Size; huart->TxXferCount = Size; huart->ErrorCode = HAL_UART_ERROR_NONE; huart->gState = HAL_UART_STATE_BUSY_TX; ...
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)); ...
if(huart->ErrorCode&HAL_UART_ERROR_ORE){__HAL_UART_CLEAR_OREFLAG(huart);}if(__HAL_UART_...
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...

摘要:当主机以比UART更高的波特率连接到单片机上时,将进入错误状态并停止向RX缓冲区的DMA传输。您可以检查HAL_UART_GetError(.)是否有错误。函数。如果出现错误,请停止UART/DMA并重新启动它。 的详细信息:首先,它不是USART_CR2寄存器中的DDRE位。CubeMX将其设置为0。但是汤姆五世的暗示把我引向了正确的方向。
