Bridgetek recently launched a series of development modules based on embedded systems. These products mainly help R&D personnel to easily implement a more complex and feature-rich human-machine interface (HMI) and ensure market differentiation. Based on the award-winning second-generation Embedded Video Engine (EVE) device, this module will allow engineers to quickly develop prototypes, and even be directly applied to terminal products as a display module. These devices have a 5.0-inch 800 x 480 pixel TFT display that can support both horizontal and vertical screens. In addition, it also contains a built-in audio amplifier, and a 1-watt speaker can be connected externally.
The first two products of this new series are ME812A-WH50R and ME813A-WH50C, which use FT812 and FT813 EVE advanced graphics controller chips respectively, and support resistive and capacitive touch screens accordingly. The module port is the slave of SPI, so an external SPI master MCU is needed for control and system integration. In the future, this series will also release a USB-based port module, which can be accessed from a PC or any other form of USB host. Modules based on capacitive touch screens provide multi-touch operations (providing up to 5 simultaneous touch points), while resistive touch screen modules allow touch operations with gloved hands (this is often required in industrial applications).
Bridgetek’s EVE graphics control chip combines display, touch and audio functions, and uses an innovative object-oriented method to implement HMI. This solution will effectively simplify the development of complex man-machine interfaces and significantly reduce the number of parts. Reduce PCB board space, suppress power consumption, etc. The second-generation EVE chip used at the core of these newly developed modules has a larger pixel resolution, clearer image rendering and greater color depth than the previous-generation EVE IC. They also have higher-speed data transmission and image loading capabilities, as well as larger memory resources to support video playback. All modules have an outer frame and 4 mounting holes to facilitate system assembly.
