Hey peeps

I'm facing a challenge with the Adafriut 9685 PWM board

I've followed the guide here and I'm able to control multiple servos through Python via I2C

https://learn.adafruit.com/adafruit-16-channel-servo-driver-with-raspbe…

FWIW, here's a video showing that I'm able to control multiple servos via I2C directly through Python outside of MRL with the PCA9685 driver board

I've then followed the MRL instructions here:

I've used the script here

With the MRL instructions I'm not getting any servo movement when using the MRL servo GUI

Any thoughts?

Update:

I notice in the MRL debug log output that I see the following when I attach Adafruit16CServoDriver service to the Raspi service:
 
Note the line: 
16:40:10.455 [gui_outbox_0] DEBUG c.myrobotlab.framework.Outbox - no static route for gui.getState 
 
This is what I see in the MRL GUI:

By way of an update for anybody that might read this post

Reverting to MRL version 1723 solved the issue for me

The good MRL dev peeps are on it :)

Thanks Grog, Mats, Kwatters for the guidance
