例如,当使用serial.write(INT)输出一个整型数 123 时,显示出的字符为"{",因为ASCII码 123 对应的字符为"{" 软件模拟串口通信——softwareserial 类库使用 除HardwareSerial 类库外,arduino还提供了softwareserial类库,可将其他数字引脚通过程序模拟成串口通信引脚 通常将arduino上自带的串口成为硬件串口,而使用softwares...
http://arduino.cc/en/Serial/Print 代码如下: chartmp[] ="hello world";voidsetup() { Serial.begin(9600); }voidloop() { { Serial.println("In DEC:"); Serial.println(tmp[1],DEC);//tmp[1] points to 'e' of the "hello world"delay(500); Serial.println("In HEX:"); Serial.println...
Serial.available() 参数 None 返回 串口已经准备好的字节数 例子 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 only when you receive data: ...
It basically packages serial data for strtok_r to split into pieces paced on predefined deliminators. Each bit of data is separated by a “,” and the end of the set of data is a “.” If you send in a string like: 1 10,50,100. You can split it into three varaibles that ...
