UCOS/II for ICCAVR
- The version of UCOS/II is 2.04
- the original port was done by Ole Saether for the IAR compiler. Jens E.
Holtegaard ported one version using ICCAVR. Joerg Meyer did another port
(using Jens port as a start?). This is basically Joerg s port plus a
little bit of changes and documentation by me.
- YOU MUST DOWNLOAD THE Main PART OF THE UCOS/II FROM THE UCOS/II WEBSITE
http://www.ucos-ii.com . The supplied project file assumes the portable
source is in the ..\source directory.
- Joerg has written couple document showing the stack frames etc. but it
is in German :-) They are included in this directory.
- The Timer2 overflow interrupt is used for Timer Tick. If you want to
change that, modify os_cpu_c.c and os_cpu_a.s
- I have tested this using ATMega103 with and without external RAM
using AVR Studio simulator. See test1.c test program. Both Code
Compressed (PRO) and STD versions have been tested.
This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer
desktop motherboard. The material covered can be broken into three Main categories: Board design
guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an
explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per
second on an actual motherboard. Section 7 contains a design checklist that lists each design
recommendation described in this document. High speed USB operation is described in the USB 2.0
Specification (http://www.usb.org/developers/docs.html).

water temperature control system uses the Single Chip Microcomputer to carry on temperature real-time gathering and controling. DS18B20, digitized temperature sensor, provides the temperature signal by "a Main line". In -10～+85℃ the scope, DS18B20’s inherent measuring accuracy is 0.5 ℃. The water temperature real-time control system uses the electricity nichrome wire carring on temperature increiseament and operates the electric fan to realize the temperature decrease control. The system has the higher measuring accuracy and the control precision, it also can complete the elevation of temperature and the temperature decrease control.
