Help I need information on wiring positions- DFRobot Forum

2013-06-14 00:34:39 [quote="kevining"]
I recently acquired the HCR robot, and am having trouble getting it up and running. The instructions/diagrams I've found don't quite match, wondering if anyone can help.

The encoders I have are different than above, the wire colors are: black, red, yellow, green, blue, orange. (There are two motors/encoders, so there are two sets of wires). Wondering if anyone has a diagram of how to hook it all up.

Thanks!

Hi kevining, I am sorry for the problem of the wire colors, we will fix it later. and I think the following site maybe can help you. [url=https://www.dfrobot.com/index.php?route=product/product&path=47_110&product_id=777#.UbmAAnSS2Uk]https://www.dfrobot.com/index.php?route=product/product&path=47_110&product_id=777#.UbmAAnSS2Uk[/url]
and the new wiki of HCR will be released soon.

;D

2011-01-26 18:47:16 Thankyou you have been a big help we got it going. Could you tell me where you got the last picture? I would like to find my answers without bothering people if possible. Diagrams like this would make all the difference. moses58

Connect the A pin of the encoder to the digital pin 2 of the Romeo.
Connect the B pin marked 4 to the digital pin 4 of the Romeo.

And also you can click the image to enlarge.

2011-01-23 18:20:10 Well it is just my luck the encorder wires are different. I have brown, grey, white and black. I can find no help on how to connect these wires to the board. All attempts to find a answer on the internet have failed. Is there anyone who has made this HCR-Mobile robot platform with sensors and microcontroller robot platform?

•Two 17w DC motors with 64:1 Gearbox 120 rpm
•Two (2 Phases) encoders with 12 PPR
•Romeo Controller board (Arduino compatible)

Thanks

Can someone send a better picture or explination?

2011-01-20 12:04:06 Thank you for the photo and code. I am visually impaired so the photo is a little to far away for my friend to clearly see the wire colors. We will try to make do. Thanks moses58

2011-01-19 20:10:21 Hi.
:)

Connect the encoder according to the picture.

The sample code:

[code]
const byte encoder0pinA = 2;//A pin -> the interrupt pin 0
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--;
}

the motor encoder wires into the microcontrolor. Can anyone help?
