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.

This is a shot in the dark - color dithering on the ESP32

ESP32 multi display with SD card
basically draw to a bitmap and then blt that to the display. you can do the latter asynchronously, so you can load, then display, and while displaying, load the next one. it won't help immensely, but it will speed things up slightly. In GFX you'd use draw::bitmap_async. There's full documentation linked to from the link I gave you above - look in "Properly doing asynchronous draws" https://www.codeproject.com/Articles/5302085/GFX-Forever-The-Complete-Guide-to-GFX-for-IoT
- GFX is now available as a PlatformIO library

ESP-IDF and SPI overhead - why I've focused on targeting Arduino
I queue a variable number of transactions, either polling or non depending on context, using this code I wrote: https://github.com/codewitch-honey-crisis/gfx_demo/blob/master/src/esp-idf/drivers/common/spi_master.hpp
- I just got my waveshare 5.65 inch 7-color e-paper working with GFX!

Dual core really faster? ESP32 versus ESP32!
In case the OP doesn't respond, I'll field your question as best as I can: You can do the rendering using a bitmap flipping algorithm along with DMA. I also know it's possible to keep the framebuffer for that display in ram, with memory left over to do bitmap flipping because I do that very thing in https://github.com/codewitch-honey-crisis/gfx_demo - that device is a Lilygo-TTGO and I have several. The above code can run on it.

Jetson Nano GPIO in C/C++
Next additions would be control of the SPI ports when I have some spare time (I do this for the LOLs really) and doxygen the functions as documentation. So anyways, if people is interested it can be found here: https://github.com/Rubberazer/JETGPIO
