AVR061: STK500 Communication Protocol
Introduction
This document describes the protocol for the STK500 starterkit. This protocol is based
on earlier protocols made for other AVR tools and is fully compatible with them in that
there should not be any overlapping or redefined commands.
The following sections describes each part of the protocol in detail. All commands
(both commands and responses) are standard ASCII characters between 0x00 - 0x7F.
Data can be any character with value between 0x00 - 0xFF.
The definition of all commands, responses, parameters and other defined values can
be found in the file "command.h". The device codes can be found in the file
"devices.h". These files are located in the software section on Atmel web site,
www.atmel.com.
At the end of this document, there is an overview of device codes, signatures, Fuse
bits and Lock bits for each currently supported device.
