How to connect encoders to romeo???
SuperMiguel 2012-04-07 12:38:49 7711 Views5 Replies Hey guys i purchased a HCR-Mobile robot platform a bit ago from you guys, and I'm trying to connect the encoders to an DFRduino Romeo V1.0 that i got from you guys few months ago.. But i can't figure out how to do it.. The only guide you guys have is: [url=http://www.dfrobot.com/wiki/index.php?title=HCR-Mobile_robot_platform_(SKU:ROB00021)#Encoder_Connection_Diagram_V2]http://www.dfrobot.com/wiki/index.php?title=HCR-Mobile_robot_platform_(SKU:ROB00021)#Encoder_Connection_Diagram_V2[/url] but it only shows how to connect it to the regular arduino no the Romeo…
Please explain how to do it.. ANd if you have some sample code of how to use the encoder i would love to see it

Would love to see the code you got working.

jtilghman 2012-04-07 12:52:06 i kinda figure how to connect them.. I did:
Green to GND
Blue to VCC
Yellow to D4
White to D1
Tried this code:
[code]
const byte encoder0pinA = 2;//A pin -> 6
const byte encoder0pinB = 4;//B pin -> the digital pin 4
byte encoder0PinALast;
int duration;//the number of the pulses
boolean Direction;//the rotation direction
void setup()
{
Serial.begin(57600);//Initialize the serial port
EncoderInit();//Initialize the module
}
void loop()
{
Serial.print("Pulse:");
Serial.println(duration);
duration = 0;
delay(500);
}
void EncoderInit()
{
Direction = true;//default -> Forward
pinMode(encoder0pinB,INPUT);
attachInterrupt(0, wheelSpeed, CHANGE);
}
void wheelSpeed()
{
int Lstate = digitalRead(encoder0pinA);
if((encoder0PinALast == LOW) && Lstate==HIGH)
{
int val = digitalRead(encoder0pinB);
if(val == LOW && Direction)
{
Direction = false; //Reverse
}
else if(val == HIGH && !Direction)
{
Direction = true; //Forward
}
}
encoder0PinALast = Lstate;
if(!Direction) duration++;
else duration--;
}
[/code]
but the motors wont move... SuperMiguel
