Missing argument in driver about robotic-arm-control

[mpi3d]

Which line did you execute?

I just executed the example.py, and I showed the error log from THONNY. But the mistake is probably the wrong driver: I cannot find the Adafruit_PCA9685.py, just an generic PCA9685.py. Can you please publish your driver?

[mpi3d]

I think it's this one: https://github.com/adafruit/Adafruit_CircuitPython_PCA9685

[Werner-G]

Oh, this is Circuit Python, not Micropython. I have no idea how to use this driver. Any chance to rework your control to Micropython using a 'standard' driver like
https://github.com/adafruit/micropython-adafruit-pca9685/blob/master/pca9685.py

Thank you!

This driver is depreciated. You should use the Circuit Python one instead. It should work on a normal Python too.

[Werner-G]

No, it cannot, see the preamble of the 'adafruit_pca9685.py'-driver: :

from adafruit_register.i2c_struct import UnaryStruct
from adafruit_register.i2c_struct_array import StructArray
from adafruit_bus_device import i2c_device

Maybe your driver only work with a RasPi, and not with ESP32? Please doublecheck your driver, I really need this for my robotic arm.

I see. Unfortunately, I don't have time to implement this. You will have to do it yourself. The driver shouldn't be much different from the actual one. Feel free to make a pull request.
