Mini Maestro and Arduino [command list?]

Support Servo controllers and servos
1

I just bought one of the Mini Maestro 12 servo controllers and it works well (once i finally got it working). I am currently controlling it from a Arduino and had a few issues getting the code working. I am not sure if the mini and the micro use different command bytes, or i just have a newer firmware then the post i tried to model my code from (https://forum.pololu.com/t/additional-chassis-level/41/1 - didn’t work for me)

Point is, this works for the Mini Maestro 12:

void setup()// run once, when the sketch starts
{
  Serial.begin(9600);// set up Serial library at 9600 bps
  pinMode(13, OUTPUT);  //for test led
}

void loop()// run over and over again
{
  put(0,3000);
  digitalWrite(13, HIGH);
  delay(1000);
  put(0,4000);
  digitalWrite(13, LOW);
  delay(1000);
}

void put(unsigned char servo, unsigned int angle){
  //servo is the servo number (typically 0-7)
  //angle is the absolute position from 500 to 5500

  //Send a Pololu Protocol command
  Serial.print(0xAA,BYTE); //start byte
  Serial.print(0x0C,BYTE); //device id
  Serial.print(0x04,BYTE); //command number
  Serial.print(servo,BYTE); //servo number
  //Convert the angle data into two 7-bit bytes
  Serial.print(((angle>>7)&0x3f),BYTE); //data1
  Serial.print((angle&0x7f),BYTE); //data2
}

Now i am trying to get the set speed function to work, but I’m running into the same issue. is there a full list of commands available for this hardware?

Hello, Rob311…

Yes. There is a full list of serial commands available. Please see the “Serial Interface” section of the Maestro User’s Guide:

In general, documentation and user’s guides for our products can be found in the Resources tab on the product page.
