Re: 16 channel servo driver

Hi!

I received the servodriver and tested it with the arduino due, but the servo is not moving. When i connect V+ the servo is twitching, but after that it's doing nothing. It is also not holding the position, i can turn the servo freely.

I tested the servo example from the adafruit homepage. On the serial monitor i can see the servonumber-output. The driver is connected to the arduino like described in the online tutorial.

The led on the servodrive is burning.

Any idea what's goning wrong?

The Due is still very much a work in progress, and we haven't tested our boards with it. We only recommend the Due to people who are comfortable with hardware hacking.

Do you have a regular arduino, like a Uno, that you can test the servo driver with?

Also, if you post some clear, detailed pictures of your assembly and wiring, we will check it for any problems.

Hi!

No, unfortunately i have just the due.

My assembly: I connected a 5,5V power supply to the blue terminal block (V+ and GND) of the servo driver.

The arduino is connected in this way:

Arduino Servodriver
3,3V ----------------Vcc
GND ---------------- GND
A4 ------------------ SDA
A5 ------------------ SCL

A4 and A5 means the analog in of the due.

Should this be ok?

No. The pinout of the Due is different that any other Arduino. http://arduino.cc/en/Main/ArduinoBoardDue
It has 2 i2c ports. One on pins 20, 21 and the other on pins SDA1 and SCL1.

Fantastic! It works :D

On Ports 20 and 21, works fine!

Thanks for the fast helping!
