我正在arduino和openframeworks之間進行串行程序。但是,arduino發送了奇怪的數據給openframeworks程序。我無法修復它,請幫助。Arduino在串口上發送 376(中斷數據?)
(Arduino的代碼)
void setup(){
Serial.begin(9600);
}
void loop(){
Serial.write('a');
delay(100);
}
(在Mac上opneframeworks代碼)
#include "testApp.h"
ofSerial mySerial;
//--------------------------------------------------------------
void testApp::setup(){
mySerial.setup(0, 9600);
}
//--------------------------------------------------------------
void testApp::update(){
unsigned char myByte = 0;
myByte = mySerial.readByte();
if(myByte == OF_SERIAL_NO_DATA){
cout << "no data was read";
}else if(myByte == OF_SERIAL_ERROR){
cout << "an error occurred";
}else{
cout << "myByte is " << myByte << "\n";
}
}
(在Xcode的控制檯)
...
myByte is \376
myByte is \376
myByte is a
myByte is \376
myByte is \376
myByte is \376
myByte is \376
...
似乎在Mac上了openFrameworks了 「\ 376」 時的Arduino沒不發送任何數據。
我的環境是,
- 的Mac OS獅子
- 的Xcode V4.3.3 SDK10.6
- 了openFrameworks v0.7.4的Mac
- Arduino的IDE v1.0.4
- 的Arduino UNO(ATMEGA328P)
- Arduino和我的PC用USB電纜連接
