/*Reading a serial ASCII-encoded string.This sketch demonstrates the Serial parseInt() function.It looks for an ASCII string of comma-separated values.It parses them into ints, and uses those to fade an RGB LED.Circuit: Common-Cathode RGB LED wired like so:- red anode: digital pin 3 th...

Get the number of bytes (characters) available for reading from the serial port. This is data that’s already arrived and stored in the serial receive buffer (which holds 64 bytes). 2 如果用串口发送一个查询命令,怎么处理好? 下面给出一个例子,微控制器通过串口读取传感器的数据。
udpSocket=newQUdpSocket(this);//我们这里只需要发送数据,并不用接收数据//connect( udpSocket, SIGNAL(readyRead()), SLOT(readUdpData()) );//绑定Arduino端口QSerialPortInfo com_info;foreach(constQSerialPortInfo &info, QSerialPortInfo::availablePorts()) ...
Arduino0029内置示例读取字符串 ReadASCIIString的主要内容和目的是从串口读取ASCII编码的字符串，解析成整数，然后控制RGB LED的亮度。以下是该示例的详细解析：硬件需求：需要一个RGB LED和相应的连接线。RGB LED的各部分针脚需要正确连接到Arduino板上的数字针脚和电源针脚。电路连接：使用四根线将RGB LED...
