Very cool.

The code is now improved, and there is an explanation of all the main code functions, in the README.

The user menu is quite nice, the AI implemented a command history (just press the up arrow key to see previous commands) and also allows for editing within the current line using the left/right cursor keys. I might reuse this in other projects that require a menu too.

Also, there's now a Python program called control_demo.py that will just cycle through colors using channels 1-3, it should be compatible with simple RGB DMX lamps either directly, or with a slight tweak.

The program works by prefixing the commands with "$" and the firmware recognised that, and suppresses verbose output, so it becomes like a simple machine interface.

This was just supposed to be a quick experiment, but I think it's almost a practical solution now, at least for some DMX use-cases.

Interesting Design! Adding the RM2, makes the controller more versatile. All that's left is adding an enclosure for the PCB![emoticon:c28b2e4cc20f4ba28d1befdba6bed29c]

Hi [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05]

Fantastic! Thank you so much for the very informative descriptions.
I've downloaded the files now and will study them and adapt them for my applications.
Great!

My application what I have is "Smart Furniture".
On Wednesday, I'm getting a Highboard dresser delivered with built-in lighting.
I'll then install an electronic door opener. This will be remote-/sensor-controlled.

Best Regards
Gerald
