It is written for the ESP32.

I've put version 0.3 on the web. Its strength is around 1960 elo (when compared with tscp running on the same platform).

Version 0.4 adds pondering.

oh and version 0.3 also added lazy smp (esp32 has 2 cores)

   3 Dog_v0.4-ESP32    :  1218.5   204.5    2545     8

Note: Dog plays on a 240MHz microcontroller here while tscp and saruman run on an 11th gen i5 at > 2.7GHz.

Woof!
Sorry - couldn't help myself.

The website now also contains a link to the source code (basically Micah with some parts ripped out due to memory constraints and some bugs fixed). Also included is a windows binary. Linux users are usually capable of creating a binary themselves.

Nice to see another engine on a microcontroller!

Thanks!

It was an interesting endeavour to get it to work. Especially since I use libchess that I wanted to use without modifications and it uses std::thread which is problematic on a micro controller (dynamically allocated stack).
