Finally getting back to playing with pico_test_synth project, this time in Arduino. Working on a new simple handmade GUI after failing to find a GUI widget toolkit for Adafruit_GFX or U8g2 that offered anything beyond text boxes

@todbot this looks great, it's pretty interesting how much you can do with just a small OLED.

I've been really impressed with lvgl for embedded UI projects. If available for your configuration you should give it a try.

@szczys I was looking at LVGL but it didn’t seem to support small OLEDs on RP2040. If you have an example, I’d be most interested.

@todbot I've used LVGL with Zephyr and thought there was support there. I'm not sure where the library ends and the platform-dependent stuff begins.

@todbot @szczys It's really not hard to write a driver. Especially if you already have the Adafruit one

Oooh, what a cool way to use two encoders to adjust a large set of parameters!

8- o

Even better, with software-defined parameters, one can can extend/contract parameter value ranges and/or add/hide/unhide/remove parameters!

8- )

I imagine that one could use this approach with other embedded software apps, such as LED controls or robotic controls or amateur radio controls.

( I need to see if I ever ordered a few of the PCBs. If not, I will have add some to my wishlist! :- )
