I am trying to use the MD25 motor controller on FEZ Domino with i2c.
I use the code from http://code.tinyclr.com/project/315/motor-driver-dm22-i2c/ which seems to be ok. The motor controller have the adress 0xB0 and 0x58 corresponds to this adress being right shifted to a 7-bit adress.
However, I can’t get this to work at all. I get no response from the controller what so ever. Can it be a voltage issue? I just connected the motor controllers SDA and SCL lines to Di2 and Di3 on my Domino and connected the grounds. Do I need any pull-up resistors?
