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...

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...

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 ...

There are some differences between UARTs, maybe I have to add more code for reset the UART3. I'm using this code on the callback: void HAL_UART_ErrorCallback(UART_HandleTypeDef *huart) { if (huart == &huart1){ __HAL_UART_CLEAR_PEFLAG(&huart1); ...
10)ErrorCode:串口错误操作信息。主要用于存放串口操作的错误信息。 UART_InitTypedef: 1)BaudRate:波特率设置。一般设置为 2400、9600、19200、115200。 2)WordLength:数据帧字长,可选 8 位或 9 位。这里我们设置为 8 位字长数据格式。 3)StopBits:停止位设置,可选 0.5 个、1 个、1.5 个和 2 个停止位,一般...
