Dog was written by Folkert van Heusden. It is (strongly) based on the chess program Micah (altought slightly different evaluation and different threading (lazy limited smp)). Licensed under the MIT license.

Don't forget to clone with "--recursive"!

Create a virtual env:

virtualenv --python="/usr/bin/python3.7" test

When you want to change options (first create the virtual env): cd app

. test/bin/activate

PATH=~/.platformio/packages/toolchain-xtensa-esp32/bin:$PATH ~/.platformio/packages/framework-espidf/tools/idf.py menuconfig

cp sdkconfig sdkconfig.esp32

To juist build the program and upload it to a wemos32 mini:

cd app
pio run -t upload

To build it for Linux:

cd app/src/linux-windows
mkdir build
cd build
cmake ..
make

To build it for windows:

cd app/src/linux-windows
mkdir buildwindows
cd buildwindows
cmake -DCMAKE_TOOLCHAIN_FILE=../mingw64.cmake ..
make

If you want to move the Dog.exe binary to an other windows system, then do not forget to copy the following files as well:

• libgcc_s_seh-1.dll
• libgomp-1.dll
• libstdc++-6.dll
• libwinpthread-1.dll

The Linux/windows versions contain a Dog in ansi-art visible when you run it with '-h'.

On windows this only works if you enable ansi-code processing in the registry (and restart cmd.exe):

reg add HKEY_CURRENT_USER\Console /v VirtualTerminalLevel /t REG_DWORD /d 0x00000001 /f

The device can have (optional) LEDs connected:

• a green led on pin 27 - blinks while thinking

• a blue led on pin 25 - blinks while pondering

• a red led on pin 22 - blinks in an error situation

• internal led is blinkd during startup
