The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Winduino: The beginnings of an Arduino emulator layer for PC
This should work with LVGL but I haven't tried it. It does work with https://honeythecodewitch.com/uix and https://honeythecodewitch.com/gfx and the example project uses that.

I've produced a couple of projects for doing graphics and user-interface stuff

UI/UX and 2d graphics libraries (cross platform)
I've developed a graphics library that supports TrueType, SVG, PNG, JPG, alpha blending and X11 colors here: https://honeythecodewitch.com/gfx/

If my ESP32 is being powered by a 5V power supply through the 5V Vin pin, can I simultaneously output 3.3V to some other peripherals in the system that require 3.3Volts
The ESP32 will reboot with a brownout message if you draw too much current. Obviously you want to avoid this, but after writing a graphics library htcw_gfx and writing a ton of drivers for many different displays, I've never had any issues running the backlight off the ESP32's 3.3v pin when plugged into USB, or even on LiPO.
- Guidance on how to get started
- htcw_gfx 1.4.6 is released
- Initial SVG support in htcw_gfx 1.4.4

Just got SVG graphics rendering on an ESP32
Thx, interesting. Made me G**gle it: https://github.com/codewitch-honey-crisis/gfx

Alternatives to LVGL for embedded graphics on a monochrome display?
Try out https://github.com/codewitch-honey-crisis/gfx - it works very well on monochrome displays and is lighter than LVGL.
- htcw_gfx 1.3.8 is out and published to PIO

- How many of you have a Lilygo T5 4.5 inch E-paper unit?
-
These E-paper displays are pretty cool
Cons: The screen is a devil to write driver code for, so you better like either the libraries that they ship with (which kinda stink, IMO), or use the one I made that works with htcw_gfx . Requires a WROVER which is weird, but fortunately it's integrated. Uses both cores to render to the display. They didn't include a display controller. The ESP32 is the display controller, so things get weird. They saved a penny or two. Would have been perfect with an SD reader integrated, but no such luck. You can order one from china for $1 and then more than 5x times that to ship it. XD
