hal_uart_error_none 是STM32 HAL库中UART(通用异步收发传输器)模块的一个错误代码,代表“无错误”状态。这意味着在UART通信过程中,没有检测到任何错误。 在HAL UART库中的作用: 在STM32 HAL UART库中,hal_uart_error_none 用于指示UART通信过程是否顺利进行,没有发生任何错误。当UART通信完成时,如果ErrorCode...
HAL_UART_ERROR_NONE：描述：无错误。值：通常定义为0x00。HAL_UART_ERROR_PE：描述：奇偶校验错误。

如果没有的话那就需要自己写ErrorCallback函数了,如下: /** *@briefUARTerrorcallback. *@paramhuartUARThandle. *@retvalNone */ voidHAL_UART_ErrorCallback(UART_HandleTypeDef*huart) { /*Preventunusedargument(s)compilationwarning*/ if(huart->ErrorCode&HAL_UART_ERROR_ORE) ...
huart->ErrorCode |= HAL_UART_ERROR_ORE; } /* Call UART Error Call back function if need be ---*/ if(huart->ErrorCode != HAL_UART_ERROR_NONE) { /* UART in mode Receiver ---*/ if(((isrflags & USART_SR_RXNE) != RESET) && ((cr1its & USART_CR1_RXNEIE) != RESET)) {...
