通过arduino实现电脑与模块之间的通讯市场上已经有许多 USB 转 TLL 调试板,但 Olimex USB-SERIAL-L 开源硬件 USB 转串口板比大多数板更先进,不仅具有 Tx/Rx 引脚,还具有 CTS/RTS 引脚,支持高达 3 Mbps 的速度,以及从 0.65V 到 5.5V 的可调电压,以满足各种板的需求。Github地址:
Serial 用于 Arduino 板与计算机或其他设备之间的通信。所有 Arduino 板都至少有一个串行端口(也称为 ...
arduino使用USB串口通信 示例代码: voidsetup() {//put your setup code here, to run once:Serial.begin(9600); pinMode(13, OUTPUT); }voidloop() {//put your main code here, to run repeatedly:if(Serial.available()) {//如果有数据可用charc = Serial.read();//读取数据if(c =='a'){ dig...

Serial.println("Enter LED Number 0 to 7 or 'x' to clear"); } 首先,我们增加命令行'Serial.begin(9600)'。这样就可以开始串行通信,这样Arduino就可以通过USB连接发送命令了。值9600称为连接的“波特率”。这是数据发送的速度。您可以将此值更改为更高的值,但是您还必须将Arduio串行监视器更改为相同的值。
USB to TTL Adapter x 1 范例说明 介绍 UART使用了两条线让双方可以同时传送资料。其中一条是Transmitting,另一条则是Receiving,双方使用约定好的频率 (baud rate) 来传资料。 Arduino 称呼UART为Serial,在Arduino Uno上只有一组硬体UART,并且这组UART主要被当作印出讯息使用(即Log UART) ,所以当Arduino要使用硬体...
