下面把最后测试的示例代码放上(代码是以测试为目的,没有把读取ID的部分代码写成函数,有点不太规范): /* UART asynchronous example, that uses separate RX and TX tasksThis example code is in the Public Domain (or CC0 licensed, at your option.)Unless required by applicable law or agreed to in wr...

定义引脚,这里TXD、RXD是串口输出通常用到数据写出和读入的引脚,关于RTS和CTS引脚 (注意:由于UART0已经的引脚配置已经固定默认在BootLoader中了,不能更改,所以不能配置引脚也无需定义) RTS(Request To Send 请求发送):用于传输PC机发往串口Modem等设备的信号,该信号表示PC机是否允许Modem发数据。 CTS:Clear to send,...

Let us see an example of serial communication where the ESP32 master will send either ‘1’ or ‘0’ to the ESP32 slave. The slave will then receive that data and control an LED connected with its digital pin. We will use UART2 to communicate between the two boards. ...
