Dear RTCU User,


Christmas time is approaching and we do not want to pass this opportunity to spoil You, our trusted RTCU users, with nothing less than the BIGGEST release announcement since the introduction of GPRS support in our units!

Logic IO is committed to bringing you the most advanced and flexible platform for GSM Telemetry/Telematics applications and we are proud to end this year with a long list of new software and hardware features.
In the coming year we are going to focus on expanding the diversity and easy deployment of our products. At the same time we will also come out with new hardware products that will insure us a place in the industry lead position - this is where we want to be! 

Today we are releasing a new version of the RTCU IDE and Firmware with many exciting new features. Please visit www.rtcu.dk

Please read all about the exciting news below.
 


The Logic IO Team wish You all
A Merry Christmas and A Happy New Year!

See you to another exciting year in 2005!


Multithreading has arrived!

This release of the Firmware for the RTCU A9i, RTCU M10 Series and RTCU M11 Series includes comprehensive support for multithreading. The multithreading extensions includes many important features that simplifies the development of complex applications on the RTCU platform, including:

  • Dynamic creation of threads using the new THREAD_BLOCK structure.
  • Explicit thread status flag that shows if a thread is running.
  • CHANNEL thread communication mechanism for easy passing of data between threads.
  • MUTEX support. Mutual Exclusion mechanism used for implementing critical sections.
  • SEMAPHORE support. The classical thread synchronization mechanism is also available.

Multithreading your code can have many benefits, including:

  • Improve application responsiveness -- Any program in which many activities are not dependent upon each other can be redesigned so that each activity is defined as a thread.
  • Improve program structure -- Many programs are more efficiently structured as multiple independent or semi-independent units of execution instead of as a single, monolithic thread. Multithreaded programs can be more adaptive to variations in demands than single threaded programs.  
  • Use fewer resources, compared to multiple program tasks.
     

The RTCU IDE on-line help and manual has been extended to include a dedicated chapter explaining the features, advantages and pitfalls using multithreading.
The RTCU IDE Manual is available here

OneWire ID-Button and Temperatur sensor


The RTCU M11 Series and RTCU A9i includes support for connecting a broad range of OneWire devices. Initial there will be support for ID-Buttons and Temperature sensors.



 

The ID-Button (shown above to the left) can be read by a ID-Button reader (shown above to the right) connected to the RTCU unit for easy and secure identification of a person/item identified with a unique ID-button. This can be used for numerous applications: driver identification, turning alarm on/off, usage registration etc. The ID-Button itself is a strong and extremely durable coin-like metal container with a unique ID. The ID-Button is usually used with the ID-Button Fob (shown to the left), that holds the ID-Button in place so that it is conveniently available whenever needed.

The OneWire based external temperature sensor can measure temperatures from -55 to 125 degrees Celsius with a precision of 0.5 degrees celcius. Comes standard with 3 meter cable.


RTCU GPRS Gateway 1.4 released:

The RTCU GPRS Gateway 1.4 has been released with the following minor updates:
  • Now includes a feature to timeout and close on inactive socket after a specified time period. 
  • The navigation in the client-list listbox has now been greatly enhanced in the situation where many clients are connected.

Bluetooth and other Wireless Technologies


 


Logic IO has succesfully implemented Bluetooth support in a prototype product and been demonstrating rudimentary communication with PC, PDA and a Bluetooth GPS smart antenna. As the technology appears now Bluetooth seems too expensive and also has certain technical disadvantages, but the technology is being continously evaluated. We are also looking into possibilities for implementing ZigBee and Wireless LAN in our products.
