资源摘要信息:"FDCAN_Receive_MASK.rar文件包含了与FDCAN (Flexível Datenraten CAN) 协议相关的配置和代码示例，特别是针对STM32G0B1微控制器使用HAL库来实现具有掩码方式的CAN滤波器配置。在CAN网络通信中，滤波器的作用是根据消息的标识符决定哪些消息被接收或者忽略。文档描述了如何设置两个滤波器来处理CAN消息的接收和发送，这是实现CAN通信中的重要部分。 在STM32微控制器的HAL库中，FDCAN通常用于汽车和工业自动化领域，因为它支持高达5Mbps的高速数据传输速率，并且提供了高效率的数据通信。FDCAN协议具有灵活性和容错性，允许设备在恶劣的电气环境中可靠地通信。 掩码方式的使用是FDCAN过滤过程的一部分，允许开发者定义哪些标识符位是“关心”的，哪些是“不关心”的。这意味着，如果设置了掩码，CAN控制器将只检查标识符中“关心”的部分，而忽略“不关心”的部分。这样可以有效地处理多个设备间的消息，特别是在一个物理CAN总线连接多个设备时。 本资源在描述中提到了接收发送，这暗示了配置不仅包括了如何接收符合特定滤波条件的CAN消息，还包括了如何设置CAN控制器以发送消息。在HAL库的上下文中，开发者可以使用HAL库提供的API来初始化CAN硬件，配置滤波器，以及发送和接收消息。 'FDCAN_Receive_MASK.rar'文件可能包含以下类型的信息： 1. STM32G0B1微控制器的FDCAN硬件初始化代码。 2. 设置FDCAN滤波器以允许接收和发送特定标识符的消息的代码片段。 3. 如何使用HAL库中的相关函数和结构体，例如`HAL_FDCAN_AddMessageToRXFifoQ()`，`HAL_FDCAN_ConfigFilter()`，`HAL_FDCAN_AddMessageToTXFifo()`等。 4. 如何根据应用需求配置掩码，以过滤掉不重要的消息，保证重要的消息被接收。 5. 如何为FDCAN接收和发送消息配置中断处理程序和回调函数。 6. 教程或示例代码，指导开发者如何在自己的项目中实现类似的功能。 考虑到文件名称列表中包含了"TFT_VCU"，虽然这个名称与FDCAN接收掩码配置没有直接关联，但TFT_VCU可能是项目中的一个特定模块名称或是文件夹名，可能与视觉处理或显示有关，这可能表明该资源可能还包含了如何将FDCAN数据与显示技术整合的内容。"

- ucCh = USART_ReceiveData(USART2);：将从 USART2 接收到的数据存储到变量 ucCh 中。 - USART_SendData(USART3, ucCh);：将接收到的数据通过 USART3 发送出去。 - if(ESP8266_Fram_Record_Struct.InfBit....

使用readyRead信号连接on_socket_receive槽，表示当套接字接收到数据时会调用on_socket_receive方法。 其中，bytesWritten信号被注释掉了，表示当套接字数据发送成功时会调用on_socket_transmit方法。

把下面代码换HAL库：void USART3_IRQHandler( void ) { char ch; if((__HAL_UART_GET_FLAG(&USART3_Handler,UART_FLAG_RXNE)!=RESET)) { ch = HAL_UART_Receive(&USART3_Handler, &ch, 1, HAL_MAX_DELAY); if( strEsp8266_Fram_Record .InfBit .FramLength < ( RX_BUF_MAX_LEN - 1 ) ) //预留1个字节写结束符 { strEsp8266_Fram_Record .Data_RX_BUF [ strEsp8266_Fram_Record .InfBit .FramLength ++ ] = ch; } } if ( USART_GetITStatus( USART3, USART_IT_IDLE ) == SET ) //数据帧接收完毕 { strEsp8266_Fram_Record .InfBit .FramFinishFlag = 1; ch = USART_ReceiveData( USART3 ); //由软件序列清除中断标志位(先读USART_SR，然后读USART_DR) } }
