Operating System Design

Comer, Douglas E., Operating System Design: The Xinu Approach, Prentice-Hall, 1984.


This is the essential text to understanding the Xinu operating system. After pouring over this, you may want to write a device driver for ATmega ADCs.

Try looking for a used copy - you can probably find one in perfect condition for about $6.





Operating System Design - Volume II

Comer, Douglas E., Operating System Design: Internetworking with Xinu, Volume II, Prentice-Hall, 1987.

Ethernet, packets, UDP datagrams, and a complete file server to run on your host computer.  Is it all outdated?  I don't think so.  I've replaced the RARP client with a DHCP client.  You don't need a time server running on your local network anymore, just address a NIST server, but there's a simple time server included in the avr distribution just in case. Avr-Xinu in this distribution is derived from XINU-68K.TAR.Z dated 12/29/1995.

It's not often that you find software so well documented.





Internetworking with TCP/IP - Volume II

Comer, Douglas E. and Stevens, David L. Internetworking with TCP/IP: Design, Implementation, and Internals, Volume II, Prentice-Hall, 1991.

This reference includes source code for most protocols including ARP, TCP, IP, RIP, and SNMP.  The Xinu operating system is upgraded to Version 8.  This version has not been ported to AVR microprocessors mainly because of its need for considerably more RAM than Version 7.








AVR Libc Home Page

AVR Libc is a Free Software project which provides a high quality C library for use with GCC on Atmel AVR microcontrollers. You want avr-GCC and  AVRDUDE too. AVRDUDE is software for programming Atmel AVR Microcontrollers.  Available here.


CrossPack for AVR

A really slick way to install the AVR Libc and all of the development tools on the Mac. Available here.  You need WinAVR for Windows.

We have implemented project templates for avr-Xinu. A few notes on the use of Xcode Templates are included.  You can download our Templates.
