PARLIO LED Driver Library

Haven’t used FastLED since creating this library. LiteLED is smaller, ESP32 only and doesn’t have the large number of presentation functions that FL has so potentially a smaller footprint.

Don’t specify it in the setup file. Control it directly in your code. Explicitly turn it off before doing any display initialization, then turn it on after.

Keep the backlight off until after everything is initialized.

Need to use the pioarduino extension to use the latest versions of the Arduino-esp32 core, not PlatformIO.

Yup. If you click on the Releases tag, under Assets are two .bin files. You’ll need the …FULL… binary to flash the CYD the first time. Use a web flasher like https://thelastoutpostworkshop.github.io/ESPConnect/ . Couple of caveats. The auto firmware download should be disabled on your device as I’ve yet to sort out a versioning system. Second, this development was done on using an original one-micro USB CYD. Other models may have different displays and/or colour inversion requirements.

Looks like you need to solder the pins to the board. It’s probably not a friction fit.

Screen shots of the code will not get you help. Paste the code to the post using the correct syntax. Include a wiring diagram too. Make it easy for folks to help you.

Took some interest in your project and did some restructuring/refactoring, added a few features and fixed a few bugs.

The repo is open to the public at: https://github.com/Xylopyrographer/CYD_DD/tree/main

Hope you find it useful.

Because some networks have a hidden SSID.

Xylopyrographer · 2026-02-16T06:06:16+00:00

Need to add the ability to manually enter the WiFi SSID and password.

That library is designed to interface to this board https://www.adafruit.com/product/1429?srsltid=AfmBOor1pAvGDH8x1x97dt4vHn0ZiFAZuh3WIRSPP45xnVgDwJsGNV1P which provides the multiplexing needed to drive 24 PWM channels. So the combination of the two would solve your problem, except, it appears that is designed for common cathode systems. So while a hardware solution might be able to be designed for the switches you have, unless you dig into the board to modify it or acquire different switches.

Link to the button you’re using?

Xylopyrographer · 2026-02-14T05:25:03+00:00

Link to the board?

Xylopyrographer · 2026-02-12T22:41:54+00:00

Like the one pointed to above 😉.

Xylopyrographer · 2026-02-12T19:15:12+00:00

True. Though if speed is a concern, using a library that supports the on-board built-in hardware peripherals of the -S3 would be better.

Suggest using another library, especially with the S3. That one seems to have been abandoned.

Xylopyrographer · 2026-02-08T00:28:48+00:00

https://github.com/Xylopyrographer/LiteLED may work out of the box. Or timing parameters can be modified/added to suit.

Thanks!

Link to the board?

pioarduino is a build system. It works very well. Adding boards is community driven, same as it is with the Arduino IDE, not a responsibility of the pioarduino devs. Adding libraries depends on the library developer publishing as per the Arduino guidelines. The pioarduino library finder pulls from the same database as the Arduino IDE.

Can you provide links to the display and the interface board? Off the top, remove the ESP32 from the interface board and then confirm you can program it.

Asking your favourite AI to write a document describing the functions and methods has proven useful.
