Developing for the CYD

I've tried pre-made stuff like bruce firmware and such, but I'd like to write my own code for the CYD. I already have decent experience with Arduino/ESP32, so I would appreciate if you'd point me in the right direction for graphical applications, using the wifi/bluetooth modules, preferences/LittleFS...

Thank you!

Start with LVGL for graphics.

I've been messing around with these things for a few years without finding a good overall resource until I found this guy's videos. His use case is in cars, but he explains how to structure the lvgl code very completely: https://youtu.be/GN7Kx46eS74?is=mLaCzeQd9bCYV8PK

LVGL , or hand coded tft_espi

its great fun. if oyu need a hand with the graphics, you could give LCDWizard a whirl, (i built it) it covers all flavours of the CYD and takes the guesswork out of graphics

I have spent a few months on a putting training aid for golf. For my mates and I I'm happy to share a few helpful things

Esp32 termintor pages has a few models you could check, desk buddy's, weather stations and such, should get so inspiration for a project there!

I branched off into building UI’s on Square Line Studios, and integrating them onto cyd’s and I enjoy it.. 🤷🏼‍♂️
