In the off-highway industry, OEMs requirements are more and more demanding. They are focusing on high-performance displays that combine an evolved and user-friendly graphical interface, similar to those of consumer electronics. Of course, they should be adoptable on multiple platforms. To meet these needs, MTA developed the Giotto and Giotto K displays, two off-the-shelf products already programmed with basic software that can be implemented by OEMs using software tools that allow for deep customization. The customizable displays use an Android-based software.

Giotto is a TFT touch screen display while Giotto K is a product that combines a TFT display with a side keyboard, for customers who prefer a more traditional approach in interacting with the display. Both products can be used as stand-alone devices or in addition to other dashboards or instrument panels. The manufacturer equipped the displays with an anti-reflective and anti-fingerprint glass. Special treatments, eliminating the air between the glass and the plastics, improve the performance under outdoor environments, increase ruggedness and durability, eliminate condensation, extend the temperature range and minimize light reflection. The materials and design solutions chosen come with an IP66-degree of protection.

The 12 V or 24 V powered products use the Jacinto 6 processor by Texas Instruments that ensures power-up time of less than five seconds. The displays are equipped with up to eight analog/digital inputs, up to two frequency inputs, two video inputs for cameras connection, two USB ports, one loudspeaker, and two power outputs. The two CAN interfaces enable integration into the in-vehicle network architecture.

Android and MTA Studio software tools

The Android platform on which the displays are based includes features like graphical elements and algorithms of reference. They facilitate the developments of applications, so that customers can customize the device to meet the specific needs of the vehicle on which the displays are installed. The HMIs can also be programmed with MTA Studio, a tool developed in-house. The software allows the customers to customize the display according to their needs, thanks to its exceptional configurability, as well as its programming with C/C++, Ladder (Livelihoods and Diversification Directions), and Functional Block Diagram for the operating logics. The MTA Studio also contains a real-time debugger and a set of libraries, with different functions available, which the customer can decide to use depending on the application requirements.
