Image of Bridgetek Pte Ltd. BT820B Advanced Embedded Video Engine (EVE) The Bridgetek Pte Ltd. BT820B 5th generation EVE is an easy-to-use family of graphics controllers targeted at embedded applications. It allows users to create advanced touch-enabled human-machine interfaces (HMI) on large LVDS displays using the same object-oriented programming model as previous EVE generations. The BT820B supports high-resolution 1920x1200 LVDS displays directly, rendering complex, feature-rich user interfaces via the frame buffer in external DDR3 SDRAM and a 16 KB display list. The Flash storage interfaces (NOR/NAND Flash and SD card) allow the BT820B to access large images, videos, animations, fonts, and more directly without requiring large amounts of Flash on the host MCU. Users may integrate live video up to 1920x1200 at 60 fps into interfaces easily via the direct LVDS video input with real-time video pre-processing to apply effects and image enhancements. The enhanced touch engine supports external capacitive touch controllers via I²C. The BT820B supports audio effects and playback via the stereo audio output (PWM/Delta-Sigma or I²S).
