Polish notation calculator project for IL2C proof of concept

What's this?

These are sample code for IL2C.

The core

"Calculator.Core" is a proof of concept for polish-notation based calculator code library written by C#.
It's very neutral implementation, not included any platform dependent code.
Target platform is .NET Standard 2.0, but IL2C can't understand external libraries currently :)

The rule for unit tests

"Calculator.Core" already independent. So we can test this library with standard .NET test technics.
The "Calculator.Core.Tests" project contains same test code using for NUnit library.

Platform implementations

IL2C translated to C language code and stored to "$(SolutionDir)Generated" directory.

Windows

"Calculator.Win32" can execute directly on Windows.
It contains platform-dependent glue functions at the bootstrap main function.

CMake (MinGW32)

This is sample structure for building with CMake.
Ready to build using CMake if you already build "Calculator.Core" and stored translated code into "Generated" directory.
"Calculator.CMake/CMakeLists.txt" is CMake script and you can build using "build.bat".

UEFI

"Calculator.UEFI" can execute directly on UEFI platform.
- Exactly, this code absolutely contains non-OSes, can boot up from USB flash memory :)
It contains platform-dependent glue functions at the bootstrap main function.
- ConIn, ConOut, OutputString, WaitForEvent, WaitForKey, ReadKeyStroke.

M5Stack

"Calculator.M5Stack" can execute directly on M5Stack with calculator FACES module.
- Exactly, this code absolutely contains non-OSes, it's firmware-level programming :)
It contains platform-dependent glue functions at the bootstrap main function.
- Bypass from-to display module (ILI9341) on SPI and Calculator-FACES keyboard (custom AVR) on I2C.
- M5_Terminal, i2c_keyboard_read
