Alpha Micro stocks FTDI’s development kits for industrial HMIs Alpha Micro has released the FTDI VM800B and VM800C development modules designed for use with the integrated FT800 EVE embedded video engine. Aimed at simplifying the design of human-machine interfaces, the VM800B is supplied with the PCB preinstalled behind a display with a bezel. The displays are offered in 3.5”, 4.3” and 5” sizes, with a choice of black or pearl bezel and a bezel mounting kit. The VM800C is the basic development module which is supplied as a credit card sized adapter board which can be purchased with or without a display (but no bezel). EVE has totally changed the way that engineers create human machine interfaces (HMIs) on QVGA and WQVGA based TFT displays. Thanks to a unique objectoriented approach, it allows more advanced HMIs to be realised across a broad spectrum of application areas - with display, audio and touch functionality all included. The VM800C module, which uses a highly integrated FT800 EVE graphical controller IC, is offered with a choice of 3.5”, 4.3”, or 5” format LCDs. A 4-wire resistive touch screen is integrated onto the specified LCD. The module also supports mono audio output with an onboard audio power amplifier and a micro speaker both included. It can be powered at 3.3V or 5V through either a 2.1mm power jack, a SPI master connector or via its USB Micro-B port. The module has a standard SPI interface so that any microcontroller with this commonly used IO can be easily connected with EVE technology. Alpha Micro www.alphamicro.net DisplayID standard future-proofed for stereo 3D and ultra-HD displays The Video Electronics Standards Association (VESA) has published the version 1.3 of its Display Identification Data Standard (DisplayID). In a move to address emerging trends in display technology, including higher resolutions and pixels per inch (PPI), the latest version of DisplayID now includes support for resolutions at 4K and beyond, tiled display topologies, stereo 3D formats and additional timing standards. The DisplayID standard was developed by the VESA members to define data structures that a video display uses to describe its physical and performance attributes. Encoded into a display EEPROM, DisplayID enables a video source to discover these display attributes, and to customize its video data stream output for the unique capabilities of an individual display. DisplayID employs flexible header and data structures that can be of varying length and number, in contrast to the fixed header and data structures used by the previously adopted Extended Display Identification Data (EDID) standard. These flexible, modular data structures enable new definitions to identify new display resolutions, refresh rates, audio standards and other formats and capabilities. One of the most exciting new capabilities, tiled displays, supports a single display that uses multiple video processors, with each video processor handling the image on one segment of the display. VESA Mapping functionality for data logging www.vesa.org software enables rich graphical display Mantracourt has updated its T24LOG100 instrumentation monitoring software to include advanced features such as a graphical / mapping capability and a facility for remote 28.6-inch ultra-wide bar type surface acoustic wave touch screen Gtouch has released an 28.6-inch ultra-wide bar type Surface Acoustic Wave touch screen measuring 707x139mm (for an active area of 698x132mm). Sunlight-readable and able to detect even the slightest touch for kiosk applications, the SAW (Surface Acoustic Wave) touch screen technology offers a better touch performance than other types of touch screens, claims the manufacturer. The touch interface allows the display panel surface to be protected for durable and stable products, with an expected lifecycle for SAW touch screens in the range of 10 years. The displays feature an explosion-proof and scratch-resistant 3mm glass cover, supporting touch operation with gloved fingers. The narrow-edged TFT panel is suitable for open-frame digital signage applications or frame type monitors. Gtouch imports large sheets of optical glass from Japan Corning, Japan AGC Glass and Germany Schott, then cuts and process the glass to match customer requirements for SAW touch panels.

The data logging package can handle up to 100 channels of wireless instrumentation data simultaneously whilst also offering a range of sophisticated features that will enable users to optimise system monitoring and control. The display software is highly customisable and can be easily branded with corporate colours and a logo to be licenced for distribution. The new mapping facility enables engineers to create a visual representation of their channels to build graphical pages showing the data in a variety of formats, including digital display or bars. The software enables a variety of image formats to be imported, including JPG, GIF, PDF and DXF.
