Firmware 2.X

4th March 2020

Removed the de-jitter feature entirely. This is an experimental firmware, not loaded on production boards.


Version 2.2

Removed the sync correction from the de-jitter feature as it caused sync instability under some circumstances (current stock version).

Palettes are:

  1. Sony CXA (unknown origin?)

The new version 2 hardware, released in February 2019, is not compatible with the old firmware (and vice versa).
