If self.regvals is None or self. "Writes an 8-bit value to the specified register/address" These changes are incompatible with anything other than stepper motors, and could short out the power supply through the HAT if anything goes wrong - which would probably trash the HAT.Īnd the method write8 should be amended as follows: The code changes are all in the Adafruit_I2C.py module. ![]() The version can also step significantly faster, but the jitter does start to build up at really fast step rates. The step rates of the varying speed motor here are twice as fast as the previous version, even when the second motor is stepping twice as fast as before the jitter is far lower for both motors. ![]() When the steps to the 2 motors coincide it impacts one or both motors. It's easy to use the DRV8833 DC/Stepper Motor Driver or the TB6612 DC/Stepper Motor Driver breakouts with CircuitPython and Python using the Adafruit CircuitPython Motor () library to control stepper motors. ![]() The level of jitter is not good, but probably not enough to cause mis-steps as long as the step rate is well below the motor's maximum. ![]() I then start the other stepper fairly slow (4 per second) and double the speed a few times. This graph is an overview run with one stepper running at about 20 steps per second.
