Hi Skelmins,

The I2C_lcd.py script/module is specifically aimed at the HD44780 chips.

If I read the docs of your display correctly, it has a AiP31068L chip combined with PCA9633 chips for controlling the colours.
The first one is the most important one (not able to configure colours is a cosmetic shortcoming).
And it seems not to be compatible (the 03e address already raises eyebrows as it is not mentioned in the configuration.txt as a possibility, but OK one never knows).

So - if I'm right -  the bad news is a choice between:
  1. create module to support this display..
  2. get a supported display..
  3. use the webgui..
The first option is doable, since the demo in your links includes a python driver script. This can be extended & merged in samplerbox with some creative tweaking.
If you're not familiar with this level of programming it will be hard to do - or an interesting experience to put it positively.
I may be able to give you a kickstart (given that your samplerbox is functioning OK except for the display and you can connect it to your home network = you can access it from your PC/laptop).

Please share your thoughts..

Regards, Hans
