Starting a big deep dive into AVR assembly.

I still cannot make my Arduino Mega's onboard LED blink, but I feel that will not be a problem for long.

okay i got an LED blinking!

can't seem to get the pre-processor to work...

Still cannot figure out how to use the pre-processor so I can use .def or #define to label the registers something other than, eg., R17.

Other than that I have set up a simple tool chain and makefile environment where I am able to successfully assemble and then upload code to the Arduino.

I suppose the next step will be to look at the People's Computer Company Tiny BASIC, ZX80 BASIC, and a few others to get some inspiration for the overall design of the language.

IIRC, it goes:

1. Lexer

2. Parser

3. Interpreter

okay, got the pre-processor to work.....
