Revised edition of µITRON3.0 Standard Handbook released

The µITRON3.0 specification, published as the µITRON3.0 Standard Handbook, has been issued in a revised edition. Besides bringing the specification up to date with the latest version, the new edition revises parts of the explanation that were inadequate or unclear, and adopts a revamped organization. Note that since the technical content of the specification has not changed since Ver 3.02.00, the µITRON specification in the case of the new Handbook is Ver 3.02.02.

ITRON-specification product registration update

The products listed in the table were newly registered as ITRON-specification products since the last issue of this Newsletter and up until June 1, 1997. For the newly registered products that implement the µITRON3.0 specification, a comparison with the µITRON3.0 compatibility checksheets can be viewed on the ITRON Home Page. Note also that the ARIOS960, ARIOS960M, HI32-200, and HI32A-200 products have been deregistered. The list of all registered products is here.

ITRON-related Publications

Listed below are the publications prepared and issued by the ITRON Technical Committee as of June 1, 1997. The ITRON-µITRON Standard Handbook is a one-volume compilation of µITRON (Ver 2.0) and ITRON2 specifications. Each of the publications below can be obtained directly from the sources indicated.

The latest version of µITRON3.0 is Ver 3.02.00. Changes made since the µITRON3.0 Standard Handbook was released (Ver 3.00.00) are noted in Newsletter No.5 and No.11, as well as in ITRON Standard Guidebook 2.

The ITRON Standard Guidebook 2 deals primarily with µITRON3.0. The earlier ITRON Standard Guidebook '92-'93 remains as a valuable reference for use with the µITRON (Ver 2.0) and ITRON2 specifications, even though the dates in its title are now past.

Plans for overseas promotional activities in fiscal 1997

The ITRON Technical Committee has various plans for promoting the ITRON specifications overseas during fiscal 1997. It will be participating again this year in the Embedded Systems Conference to be held in San Jose in late September and early October. And in Asia, a seminar will be held in Seoul, Korea.

The Embedded Systems Conference (ESC) is the world's biggest trade show in the embedded systems field. Sponsored by Miller Freeman, Inc., the show is held twice a year, once on the U.S. East Coast (ESC East) and once on the West Coast (ESC West). Of these, the ITRON Technical Committee each year takes part in ESC West, the larger of the two events. This year as last, the venue is the San Jose Convention Center in California, where the show will run from Monday, September 29 through Thursday, October 2. This year the ITRON Technical Committee will be exhibiting in a joint booth with the Japan System House Association (JASA), with the focus on promoting the ITRON specifications.

As a promotional activity in Asia, this year an ITRON seminar is being planned for Seoul, Korea. A similar plan was made for the previous fiscal year but could not be carried out. The date and other details are still pending.

The committee is looking for suitable opportunities to promote ITRON in other parts of the world as well, including other Asian countries and Europe. Anyone interested in learning more about overseas promotional activities for ITRON is invited to contact the ITRON Technical Committee.

Presentation at Embedded System Solutions '97

ITRON Technical Committee secretary Hiroaki Takada of the University of Tokyo gave a presentation on the latest trends in the ITRON specifications, at the Conference portion of Embedded System Solutions '97. The conference and exhibition, sponsored by the Japan Electronic Industry Development Association (JEIDA), took place in Tokyo from April 15 through 18.

Mr. Takada's presentation was given on Friday the 18th, the final day of the event, from 1:30 to 3:00 p.m., before an audience of around 80 persons. He gave a brief overview of the ITRON specifications, then described the work of the Hard Real-time Support Study Group and the Embedded TCP/IP Technical Committee toward creating industry standards. He also introduced new projects such as the work of the RTOS Automotive Application Technical Committee. Other topics covered in the presentation were the results of a survey on ITRON use trends, conducted at the end of last year and early 1997, and activities aimed at promoting ITRON overseas.

Newly registered products

Two of the new products recently registered with the TRON Association are introduced here. Because of the large number of products registered since the previous issue, introductions to the RX116, RX136, RX320, RX423, and HI8-2600 OSs will be given in the next issue of the Newsletter.
