My tasks for the week:
- Work on interface between motor controller board and Pi
- UI fixes (e.g. selecting an object to track from live video) (not as important)
- Automatic calibration for the compensator motor’s speed using CV (not as important)
What I have from this week:
Two squarewaves in quadrature from the GPIO pins of the Pi, at a much lower frequency than necessary for the PWM signals for motor control. (I don’t have an oscilloscope, although I might be able to hack something together with an Arduino, if I can find one) These are for the unipolar stepper motors for the compensator and test setup.
I lost some time trying to set up the Pi, and I’m also working on porting the code from the last few weeks to the Pi.
My progress: I’m behind on the motor controller interface. I expected to have more done.
Next week: More work on the motor controller interface.
