Arduino的Serial.readBytes()使用例子 找了很久终于在德国一家个人网站上找到的,找了很多,这个比较容易理解,因为不太会用这个语句,写出来以免以后忘记又可以在这里找到啦。真是功夫不负有心人呀,嘻嘻。 源代码注释是德文,我用翻译好用括号括起来了,方便理解。这段代码是通过串口发送字符来PWM LED亮度的代码,似乎...
还有readBytes/readBytesUntil/readString/热爱的StringUntil setTimeout() 设置串口超时时间,默认1000ms write()写二进制数据到串口 serialEvent()串口数据准备好时触发的事件函数 4.4 I2C总线接口(半双工)(考的简单) 内部集成电路(Inter-Integrated Circuit ,I2C),是具有多主机系统所需的包括总线仲裁和高低速器件同步...
This example demonstrates string-based communication from the Arduino board to the computer using a call-and-response (handshaking) method. 本例展示了 Arduino 和电脑间的,基于字符串的调用和应答(握手)通信。 The sketch sends an ASCII string on startup and repeats that until it gets a serial respo...
The readline() function will read all bytes until a newline character is detected. If we just printed what we received we would see b’Hello from Arduino!\r\n’. You receive bytes when you read from Serial, and you have to convert (decode) those bytes into the appropriate data type. ...
由readBytesUntil引起的Unity和Arduino之间的SerialPort延迟 、、 我已经用unity游戏引擎创建了一个游戏,并与arduino进行了双向串行通信。我可以使用Serial.println将数据发送到Unity,没有任何问题。然而,当我试图从Unity向Arduino发送一封信时,我得到了令人难以置信的延迟。延迟是由以下代码引起的。它减慢了整个游戏的速度...
Serial.readBytes(sbuf, len); //将UART端口数据推送到所有已连接的telnet客户端,实现双向通信 for(i = 0; i < MAX_SRV_CLIENTS; i++){ if (serverClients[i] && serverClients[i].connected()){ serverClients[i].write(sbuf, len); delay(1); } } } } 1.2 SF1 STA模式-连接路由器-设置AP-...
