TinyDuino Processors & TinyShields / Re: stepper motor + dual motor shield

Thanks for posting this, I was about to ask about this shield and stepper motors as I realised after purchasing the shield that the PWM is sent over I2C to control the output of the H-Bridge. It seems to me you need to pulse each input in the expected sequence and the motor should step (in theory), not tried it yet. It would seem that instead of relying on existing libraries, I'll have to come up with my own loop (would it be possible to microstep do you think?)
For my application I want to use a stepper like an accurate pointer, like the hour hand on a clock, so I just need to move it to a pre-determined angle and then return to the starting point. With no particular feedback I guess I'll just need to count the steps carefully.
