esp32-pc

This repo is currently a work in progress. I am currently working on the ESP32's command line.

bad-apple-test-7.mp4

Yes, it does run Bad Apple! (Make sure to run net stop before using readimgseq). A some recent updates have sped up the playback speed monumentally, and the device is now capable of ~16fps playback!

Currently, the master device will now allow up to 8 slave devices to sync to it over WiFi. It can also read from an SD card filesystem.

One of the latest updates included the ability to take screenshots. The screenshot algorithm will be improved later to use run length encoding, which should speed it up significantly.

I call it, "The Signal Integrity House of Horrors".

Why am I doing this?

I have quite a bit of experience programming on high end desktop computers, and thought that it would be useful to learn how to program on a system with much tighter tolerances and lower specs.
