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.

Just Released My ESP32-S3 Audio Dev Board
If you're getting started, the ESP8266Audio library makes it easy to play audio with the Arduino toolchain. For more advanced use cases, Espressif's own ESP-ADF has a lot of useful features and examples.
- Creating an 8-channel, 16-bit audio recorder with ESP32 -- possible?
- ESP32-LyraT webradio / mp3 player with web interface
- US516P6 offline voice assistant
- Is there a library for streaming uncompressed stereo audio from a device to esp which then can feed a amplifier (digital, analog or toslink)?
- Playing audio to bluetooth headphones?

- Guidance on how to get started
- htcw_gfx 1.4.6 is released

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

Since so many people have a little TTGO Display T1...
The graphics library to drive the display is htcw_gfx, as I mentioned, https://honeythecodewitch.com/gfx/ which includes true type font and jpg support built in.
-
I've updated my Sonos remote code
Also just as importantly, this runs the htcw_gfx graphics library through its paces, so it's a good starting example of how to use some of the core features like JPGs and Truetype fonts.
-
htcw_gfx high performance batching with the TTGO T1
As some of you may know I'm the author of the htcw_gfx library for IoT. The library supports TrueType fonts, JPGs, alpha blending, automatic color matching for indexed devices like color e-paper displays, X11 colors, arbitrary pixel and bitmap formats and automatic conversion between different pixel formats. It was designed as a bit more high level of a library than something like TFT_eSPI, and is built using C++isms and Generic Programming, so templates are what's for dinner.

Demo of using htcw_gfx with the LCD Panel API
It *is* possible to use htcw_gfx with this API, as long as you're willing to draw to a bitmap and then send that bitmap to the display. It's pretty easy to do from platformIO under arduino or the ESP-IDF.
- Noob question : Can the esp32 replace arduino?
-
What Framework you prefer?
htcw_gfx makes heavy use of templates and metaprogramming to allow for things like arbitrary binary pixel formats that wouldn't be feasible to compute and manipulate at runtime. The documentation covers what it looks like to use it.
- How many of you have a Lilygo T5 4.5 inch E-paper unit?
