Project mention: Writing an Embedded Chess Engine - Part 5 | /r/avr | 2023-05-24

I have written hundreds of game engines over the years including many more full-featured chess engines (JavaChess, CPlusPlusChess, JavascriptChess to name a few). A few months ago we saw many great chess board projects in the various microcontroller and electronics subs here on reddit but all of them focused on the electronics and construction of the game boards themselves. From the discussions and comments that followed it seemed that many of the authors had the same questions about how to write the code-behind.

NOTE: The open source projects on this list are ordered by number of github stars. The number of mentions indicates repo mentiontions in the last 12 Months or since we started tracking (Dec 2020).
