Adding Toasted Thumb Programmer (TTP) support to the Arduino IDE

[G. Andrew Stone]

To allow the Arduino IDE to use the thumb programmer as a chip programmer, you'll need to add a board in the Arduino's "boards.txt" file.

This file is located at <base dir>/arduino-1.0/hardware/arduino/boards.txt in Linux.

I cannot describe all the parameters for boards.txt here.  But basically, to use the TTP you simply need to set the "protocol" to "stk500", like this:
solo_mega328_tpp.upload.protocol=stk500

You'll also need to change fields based on the particular chip you are using.  Here is an example for the ATMEGA328.  Note that this is NOT the standard Arduino ATMEGA328p chip! (for that one, just change it like this "solo_mega328_tpp.build.mcu=atmega328p").  ***To use a ATMEGA328, you'll also have to change the avrdude.conf file***

Here are 2  examples for the Atmega48 chip -- the first uses the TTP, the second the Adafruit's usbtiny programmer:

The attached file provides a complete example, and includes the "Lightuino5" boards which contain TTP embedded in them...

Cheers!
