I can't remember who shared this link but it was really a fascinating watch and an interesting look into a different way of thinking about embedded programming and power usage.
M8 Teensy based hardware #tracker
The developer has a github with a lot of repositories. (mostly docs and precompiled binaries)
Ther is a way to run the firmware headless using your computers keyboard, monitor and audio if you don't have all the hardware
Rewrote the game of life demo without MUL/DIV using only bitwise arithmetic. Much faster.
Tonight I ported @email@example.com 's Uxn VM to the MegaGRRL hardware (my ESP32-powered VGM player). Seemed like it would be fun, and it was :)
Here is a little demo...
Had to lower the screen resolution (not enough RAM for full screen framebuffers!), but it has sound, output through the YM2612's DAC register. D-pad emulates a mouse. Also had to do a bodge to the drum-rack example to get it working on the lower resolution.
Finally got a semi decent image from NOAA 19 on my baofeng uv5r.
This is a false color image and the raw+infrared image (you can make out some clouds as well as the west side of Africa)
The boafeng doesnt really have enough bandwidth to get a full quality image and it's really easy to accidentally move and mess up the signal (which you can see in the vertical lines)
I still haven't managed to get my SDR working for this (think i might need a different antenna)
