read() 返回串口缓冲区的一个字节。如果没有数据则返回-1。Arduino官方提供的一个参考例程很好的展示了如何从串口读数据。 int incomingByte = 0; // for incoming serial data void setup() { Serial.begin(9600); // opens serial port, sets data rate to 9600 bps } void loop() { // send data ...

1.查看X3派上python是否安装serial包 2.X3派与Arduino之间通过USB进行通信 3.在终端上输入 ls /dev/tty* 出现ACM0说明两者可以正常通信 4.在Arduino上烧录代码 void setup() { Serial.begin(9600);}void loop(){ if ( Serial.available()) { if('s' == Serial.read()) Serial.println("H...
Serial.println(data.intValue); // 假设我们要读取的数据是一个浮点数,存储在地址4开始的位置 readFromEEPROM(4, &data,sizeof(data.floatValue)); Serial.println(data.floatValue); // 假设我们要读取的数据是一个字符数组,存储在地址8开始的位置 readFromEEPROM(8, &data,sizeof(data.charArray)); Seri...
USB cable. Bytesare sent one after another (serially) from the Arduino to the computer.You can use the Arduino Serial Monitor to view the sent data, or it can beread by Processing, PD, Max/MSP, or any other program capable of reading datafrom a serial port. The Processing code below ...

我有许多 Windows 2000 系统,我们正在尝试使用它们来对新的 Arduino Uno 和 Mega 设备进行编程。这些板现在配备了 USB 连接,是之前FTDI的升级版。 。我无法从 Windows 2000 系统将 Arduino 代码下载到开发板上 提供的驱动程序是 *.inf 文件,用于修改 Windows(在本例中为 Windows 2000)附带的标准 USB 驱动程序。
