My project is control helicopter by kinect (processing), first time, i try to transmit IR for motor board . When i post a symbol to IR transmiter board, i see it delay 5s.
But, i used Serial Monitor to send a symbol and it has no delay.
then i use kinect to send the symbol to control motor board and it has no delay.
I think the problem on my IR transmiter code.
Please help me and thank you.
This is my code:
arduino ir transmiter
#define RED 4
#define led 7
int incomingByte = 0;
int throttleCmd = 0;
char cmd;
void setup() {
Serial.begin(9600);
pinMode(RED, OUTPUT);
pinMode(led, OUTPUT);
}
void loop() {
if (Serial.available()) {
cmd = Serial.read();
//=================================== IF =================================
if (cmd == 'a') {digitalWrite(led,HIGH);Transmit(10);}
else if (cmd == 'b') {digitalWrite(led,LOW);Transmit(20);}
else if (cmd == 'c') {digitalWrite(led,HIGH);Transmit(30);}
else if (cmd == 'd') {digitalWrite(led,LOW);Transmit(40);}
}
}
void Transmit(byte rudder) {
static byte Code[1];
byte mask = 128; //bitmask
int i;
Code[0] = rudder; // 0 -> 127; 63 is the midpoint.
OutPulse(2002); // Start 38Khz pulse for 2000us (2002us is evenly divided by 26)
delayMicroseconds(2000); // 2000us off.
// Loops through the Code[i]
for (mask = 128; mask > 0; mask >>=1) { // See Arduino reference for bit masking (really cool stuff!)
OutPulse(312); // Sends 312 pulse each loop
if(Code[0] & mask) { //If both bit positions are 1 you get 1
delayMicroseconds(688); // send 1 (700 off)
}
else {
delayMicroseconds(288); // send 0 (300 off)
}
} //End mask loop
OutPulse(312); //Send 300 microsecond Closing Pulse
delay(60);
} // End Transmit
void OutPulse(int Pulse) { //sends 38Khz pulses over the Pulse Length
int p;
for(p = 0; p < (Pulse / 26) - 1; p++) { //Takes about 26 microseconds per loop
digitalWrite(RED, HIGH);
delayMicroseconds(10);
digitalWrite(RED, LOW);
delayMicroseconds(10);
}
} //End OutPulse
