HMI Hardware Resides In Credit Card Sized Package

Bridgetek’s entry-level HMI hardware development modules measure about the size of a credit card (54.1 mm x 85.6 mm) and support a range of different display configurations. The VM816C modules each feature a BT816 device. Users will be able to employ the functionality offered by the latest generation Embedded Video Engine (EVE) technology and apply it to their human machine interface (HMI) designs. They will benefit from the BT816’s adaptive scalable texture compression (ASTC) capabilities.

 

The modules are offered with either a SPI to connect directly with an SPI Master - namely an external system microcontroller or microprocessor, or as a USB variant for developing display lists to be trialed via a host PC. They can be ordered as a PCB assembly incorporating a 5-in. WVGA (800pixel x 480pixel) resolution TFT display with a resistive touchscreen, with the display supplied loosely. Alternatively, it is possible to specify one without the display included - thereby giving the user the flexibility to connect with their own choice of display (addressing 4.3-, 5.0-, and 7-in. form factor preferences).

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

The audio capabilities of these modules each comprise of a three-stage audio filter and a power amplifier, as well as a connector port for attaching an external speaker. 16 MB of on-board Flash memory connected to the new BT816 dedicated flash host port is also included for storing graphical content. A variety of different power sourcing options are covered - with the required 5V being delivered via the SPI host connector, the USB Micro-B port, or the 2.1 mm dc power jack. In order that engineers can get started quicker, Windows-based sample applications plus numerous additional demos are provided with this development package. For more info, visit Bridgetek.
