Chapter 1described how to connect the Arduino serial port to your computer to upload sketches. The upload process sends data from your computer to Arduino and Arduino sends status messages back to the computer to confirm the transfer is working. The recipes here show how you can use this commu...
Serial.begin(speed,config) 初始化串口,speed波特率,config数据、校验、停止位 Serial.end() 释放串口通信引脚,使其作为普通引脚 Serial.find(target) 在缓冲区中搜索target,找到返回 true,否则返回false Serial.findUntil(target,terminal) 搜索target直至terminal,无返回值 Serial.flush() 等待正在发送的数据发送完成 ...

The module has two different modes to operate in; serial communication mode (connecting to a microcontroller) or AD button control mode (module can be controlled with switches). This project uses AD button control only. The timer alert files are in mp3 format and have to be uploaded to the...

从Tools(工具) | Serial Port(端口) 中选择Seeeduino XIAO的串口号。 这应该COM3或数字更大的串口(COM1 和COM2 通常为硬件串行端口保留)。如果您不知道是哪个,您可以断开Seeeduino XIAO并重新打开菜单; 消失的条目应该是Seeeduino XIAO。重新连接电路板并选择该串行端口。
