more arduino/cpu thoughts: (2006.12.19:1 cpu#3 tech_notes#320)

• 1] The bootloader is only used for serial/USB communication with the board/ATMega8 and writing code to flash. This is not necessary as we can upload staright to flash using the AvrUsb500 Programmer Kit mentioned below (notes on this to follow).
• 2] Makefile:

http://www.arduino.cc/playground/uploads/Learning/Makefile

# This makefile allows you to build sketches from the command line
# without the Arduino environment (or Java).
#
# The Arduino environment does preliminary processing on a sketch before
# compiling it.  If you're using this makefile instead, you'll need to do
# a few things differently:
#

then compiles and links with Arduino library .c (and .cpp) files

and further compiles using avr-gcc, avr-objcopy and so on and uploads with avrdude.

• 3] for our CPU we need a new language which will compile to... perhaps using Chicken Scheme Scheme-to-C compiler as intermediary

or rather:

an interpreter or vm (virtual machine) in flash

http://amforth.sourceforge.net/

as in:

amforth is a distribution of Forth running on the AVR ATmega microcontroller. Once put into flash, it needs only a serial connection to the host computer. New words are compiled directly into flash, thus extending the dictionary immediately. It is ans94 Forth oriented with some minor exclusions and a few words from the extension word sets. It is written in assembly language and Forth itself. The main development uses ATmega8 and ATmega32 controllers; other ATmega controllers should work with small adjustments.
