INDUSTRY INTERVIEW


Itron UK has over 20 Years of Electronic Display Innovation. Here Electronics Today speaks with the company to find out more about its iDEVOS platform


What are the main application areas that Itron UK addresses? Vending was the first application to shape the Smart TFT product range and the direction of the iDevOS operating software. Customers were using monochrome displays and wanted to upgrade to full colour without changing their host CPU, which in many cases was a low cost 8/16 bit CPU. Equally, the display communication commands and data needed to be compact and user definable which often meant the customer modifying just 10% of their existing code to support the cursor positioning and colour capability of the larger colour TFT display. We also supported multi-language capability, typically 8 options including Japanese while minimising memory usage and development costs. Industrial, Scientific & Medical Instrumentation is now the main market, which has similar demands to Vending but often with lower annual quantities. The low cost of ownership provided by the Itron UK display solutions was key to making these markets viable for many UK customers wanting to use a colour TFT. A TFT display requires significant data memory and clock speeds (~ 26MHz) which tend to be supported by 32 bit CPUs which also come with touch control, analogue to digital converters, serial interfaces and numerous digital ports plus maths processing,

timers and counters. It proved beneficial to provide these non- display features to customers so cost reducing and simplifying their hardware design. Built-in data logging proved to be the most popular add on feature for these instrumentation markets, with the display providing rapid-access to review stored data and the interfaces supporting transfer to network or memory card storage. There are specific applications in Transportation, Utility Metering and Building Control where time to market, available internal resource and end customer specification have made our product range the preferred choice. With PCB design, firmware development and manufacturing under one roof in the UK we can provide a modular solution with bespoke options to match evolving application demands.


In relation to OEMs and customers in general - how advantageous is the use of the company's iDevOS operating system against other systems available on the market? The early customer applications and the display CPU processing power shaped the iDevOS operating system into a very flexible and easy-to-use solution optimising design cost and display
