Haptics & user interfaces Touch panel adds complete HMI to Raspberry Pi 4D Systems ( Sydney, Australia) and distributor element14 have introduced the 4DPi-24-HAT, a touch panel that enables the display to function with the Raspberry Pi without the need of a mouse or an alternate HMI device. 4DPi-24-HAT is a 2.4-inch, 320x240 pixel fully HAT standard compliant primary display with resistive touch that plugs directly on top of a Raspberry Pi. It displays the primary output of the Raspberry Pi, which is normally sent to the HDMI or Composite output. The integrated Resistive Touch panel enables the display to function with the Raspberry Pi without the need for a mouse or an alternative HMI device. The 4DPi-24-HAT is designed to work with the Raspbian Operating System and is powered directly off the Raspberry Pi’s 40-way header requiring no external power supply and allows touch-based interaction with the Raspbian Operating System. The display has a typical framerate of 25 frames per second, which can be increased with kernel compression. The display’s backlight can be turned on or off using an on-board jumper or dimmed using PWM controls. The on-board EEPROM allows for quick identification of the 4DPi-24-HAT by the Raspberry Pi. The 4DPi-24-HAT is compatible with Raspberry Pi A+, B+ and Raspberry Pi 2 and is fully HAT Standard compliant. 4D Systems www.4dsystems.com.au First 6-inch 4K AMOLED panel targets VR devices EverDisplay Optronics (EDO) has launched what is claimed to be the world’s first 6-inch 4K AMOLED display. Although 4K TV is already commonplace among the consumer market, replicating the same resolution onto a 6-inch panel has demanded a hike up to 734 PPI and represents a hundred fold scale challenge in terms of both design and process. The advent of the 6-inch 4K AMOLED panel, which has a resolution of 3840 x 2160, opens up wider possibilities for newer applications, such as virtual reality (VR). Whether smartphone display demands super high resolution remains to be seen, but a host of new applications would definitely use much more pixel packed displays. More than perfect color, AMOLED displays offer low latency, real darkness with superb contrast ratio and minimal hazardous high-energy blue ray. All those features are ideal to support VR devices. EDO has been quickly catching up on the industry, first with HD resolution from March 2014 to FHD, then WQHD (2.5K) and UHD (4K) today, all done in less than 18 months. With its 6-inch 4K display, EDO has projected itself to the forefront of first tier in the industry. EverDisplay Optronics www.everdisplay.com SVGA TFT LCDs rated for 11 years, 24/7 in harsh applications MSC Technologies offers two SVGA (800 x 600 pixels) TFT LC displays from NLT for harsh industrial applications. The LCDs integrate long-life LED backlights that provide 100,000 hours of operation, a new breakthrough for NLT products. This corresponds to a continuous operating time of eleven years for 24/7. The long-life backlight reduces significantly the maintenance times and costs of the visualization system. Thanks to their extended temperature range of -30°C to +80 °C, the robust displays are also ideal for outdoors. Typical fields of application are factory automation, analytical instrumentation as well as high-performance test and measuring equipment. The NL8060AC21-21D and NL8060AC26-52D TFT LCDs available in diagonal sizes of 8.4-inch (21.34 cm) and 10.4- inch (26.42 cm) deploy ColorXcell technology developed by NLT that ensures true color reproduction combined with low power consumption. The typical power consumption is specified as 3.4 W (4.7 W for the larger display). Furthermore, the displays provide the technical data required typically for industrial applications: A luminance of 400 cd/ m² (typ.) and a contrast ratio of 800:1 (NL8060AC21-21D) or 900:1 (NL8060AC26-52D). The color palette covers 16.77 million colors. Viewing angle is 160 degrees (horizontal and vertical) and the display surface is coated with an anti-glare film. The NL8060AC21-21D measures 200x152x8.2mm, the NL8060AC26-52D is 243x185.1x10.5mm. MSC Technologies www.msc-technologies.eu Automotive HMI design suite shapes digital instrument clusters Integration of Green Hills Software’s Integrity real-time operating system with Luxoft’s Populus Suite HMI design tool chain enables its use many MCU platforms that are frequently employed in automotive digital instrument clusters Together with the use of Green Hills Software’s Multi integrated development tool chain, this combination allows Populus to run on a wide range of automotive grade microcontrollers (MCUs), enabling the creation of robust digital instrument clusters with a low memory footprint. Luxoft’s Populus is designed for operation using a low memory footprint. By addressing the specific features of the MCU, a highly optimised Populus runtime engine enables the combination of a high performance HMI with very low memory consumption for both the engine stored in the flash memory as well as the RAM memory needed during the runtime. Luxoft’s Populus Suite enables the rapid HMI development for customisable, 2D or 3D, fully digital instrument clusters, head-up displays (HUD), in-vehicle infotainment systems and entry level to mid-tier Head Units. Security is achieved by the use of hardware memory protection to isolate and protect embedded applications. Secure partitions guarantee each task the resources it needs to run correctly and fully protect the operating system and user tasks from errant and malicious code, including denialof service attacks, worms, and Trojan horses.
