Hi

I need to use 2  Dual Motor TinyShield boards. According to the docs I need to remove a resistor in one of the boards (i.e. R1) The resistors are tiny and I do not wan to damage the board. Is this correct?

Also, how should I declare the motors in the second board, something like:

MotorDriver motor(0);
MotorDriver motor1(1);

// Motor1 board 0
motor.setMotor(1,i);
// Motor2 board 0
motor.setMotor(2,i);
// Motor1 board 1
motor1.setMotor(1,i);
// Motor2 board 1
motor1.setMotor(2,i);

Thanks

Yep, 0402 resistors are pretty small- the easiest way to 'remove' them in my opinion is to scrape off the top black coating- that's the conductive part. I believe the documentation says which address the resistors correspond to- if not, I'll fix that.

Your code looks correct, that's how to declare them.

Thanks,
Ben

Hi

One last question, what's the value of the resistance?

To be sure that I did it correctly I measured it and it gave me like open circuit. Is that correct?

Correct- the resistance across the pads should be 'open' after scraping/removing the resistor.

Where do I find complete documentation on using the MotorDriver class?

It looks like we don't have more than what's in the examples and tutorials- we have just added two more members to our team and documentation is a priority, so this will be fixed as soon as possible. Let me know if you have specific questions until then.
