Would it be possible to get this working with adafruit pca9685 16 servo?

[petrella56]

Hey I've been looking all over to get face tracking servos on pca9865 16 servo driver but can't seem to find any projects that work is there any way that I can modify this one or can anyone help me??

I took a look at the pca9865 python library https://learn.adafruit.com/16-channel-pwm-servo-driver?view=all#python-circuitpython and https://circuitpython.readthedocs.io/projects/servokit/en/latest/

It is possible to add the pca9865 servo control to the code. I did modify to use GPIOZero and you can see separate implementations for openelectrons and gpiozero servo libraries. Could also add pimoroni and waveshare pantilt per https://github.com/pageauc/waveshare.pantilthat .
pac9865 python library must use python3 and you will need opencv3 as well. The face tracking demo has not been touched for quite a while and like anything the code is a snapshot in my programming skill timeline.

This code looks like it would need a good overhaul and I will think about visiting it in the future. I do not have a pca9865 board as well.
Depending on your skill level you should be able to add pca9685 support.

Hey thanks for the quick reply! Honestly I'm pretty new with python I mean I have a basic understanding but this is a tough one for me is there any way u can help me out? Or reference me to someone that has done this ? Thanks for taking the time to read this :)

The main program logic would remain the same. Just the code to load the required python libraries and move the servos would need to be modified. This code was written a while back and could be written better to allow swapping out the servo implementation in a more generic way. I do not have the adafruit 16 channel servo controller https://www.amazon.ca/dp/B00EIB0U7A/?coliid=I2W380IA7V2H67&colid=1HPBO3AH0W9I9&psc=1&ref_=lv_ov_lig_dp_it but I can order one. It would be sometime in the new year before I could get one.. I have a bunch of servos that I bought in bulk and I have an old metal pantilt assembly that I can use. Will see what I can do but it would be next year.

Thank you pageauc for the quick reply i really appreciate it and just wanna say your awesome, also I'm gonna try making it work in the mean time but definitely interested in seeing the project 😃

FYI. I found this github project that might be of interest to you
https://github.com/allmyservos/allmyservos
BTW
I am still looking at rewriting face tracking demo so it can use dagu, pimoroni, waveshare, gpiozero or PCA9685 pantilt servo control. It will take a while.
