EVE stands for Embedded Video Engine and refers to a graphic controller from Bridgetek/FTDI.
EVE graphic controllers are easy to use and can control the display, touch, backlight, and audio features of an embedded system, with each appearing to the host MCU as a memory-mapped SPI device. The host MCU sends commands and data using SPI protocol. Crystalfontz EVE modules accept high level commands, simplify writing images and fonts (included angled fonts) on TFTs. Fonts, buttons, and tables can each be easily sent to a TFT using a one-line command.
Crystalfontz carries multiple display modules that feature an EVE chip.
