This is a simple (and tiny) text based menu system for arduino projects.
You instantiate the menu class and then run it with a table indicating which C functions should be called when a 'menu item character' is entered.
I built this so that I could put isolated pieces of code in the menu handlers and then debug with the scope or volt meter or other debug tools.
Its an easy way to slow things down, without having to use a debugger - and you can also have other, less code-oriented operators use it for test & validation.
To install, copy copy the "andys_menu" into your Arduino libraries directory.
Include in your project as per the example code in example/example.ino.
Drop me a note on twitter - @andyidsinga - if you find it useful or need help.
