Arduino - -- 串口双向通信 需要用到Arduino UNO的串口双向通信功能,以下源码: int val; void setup() { Serial.begin(9600); // opensserial port, sets data rate to 9600 bps while(Serial.read()>= 0){}//clear serialbuffer } void loop() { if (Serial.available() > 0) { delay(100); /...
Arduino 串口篇 Arduino发送十六进制 send HEX via serial port RS232-to-USB to PC 发送十六进制比较直观,可以在上位机中直接获取十六进制的数据,然后在在上位机上将十六进制HEX转换成BIN(二进制)或者DEC(十进制)就十分简单有效了. 下面是在Arduino上怎么演示直接发送16进制. 详细请参考官方说明: http://arduino...

//注意:Delphi2010以下版本默认的字符编码是ANSI,VS2010的默认编码是UTF-8,delphi版得到的字符串须经过Utf8ToAnsi()转码才能跟C#版得到的字符串显示结果一致. //Delphi版: function HexToStr(str: string): string; function HexToInt(hex: string): integer; var i: integer; function Ncf(num, f: integer)...
