+  Serial for UART2
+- 使用"HardwareSerial"类进行串行通信。它有一些重要的接口：
+- HardwareSerial(int uart_nr)：这是HardwareSerial的构造函数，其中uart_nr为0,1或2，所以我们有最多3个串行端口。
+
+- void begin(unsigned long baud，uint32_t config = SERIAL_8N1，int8_t rxPin = -1，int8_t txPin = -1)：用初始化串口:波特率,串口模式（默认为SERIAL_8N1）,rxPin和txPin（如果您保留这些参数为空库将使用默认引脚）。
+- available()：获取从串口读取可用的字节数（字符）。
+- print()：将可读的数据使用ASCII打印到串行端口。
+- println()：将数据使用ASCII打印到串行端口，后跟回车符（ASCII 13或'\ r'）和换行符（ASCII 10或'\ n'）。
+- read()：读取Rx引脚上输入的串行数据。
+- readStringUntil()：将串行缓冲区中的字符读入字符串，直到遇到终止符。
+- 因为Arduino库创建了一个默认实例HardwareSerial Serial(0)，因此您可以直接使用创建的Serial对象，而无需自己创建实例。
+- 为了使用更多的串行端口，您只需创建另一个HardwareSerial实例，例如：HardwareSerial Serial1(1)或HardwareSerial Serial2(2)，然后常用方法使用它们。
