UPHCC-lcd

UPHCC-lcd is a USB-based (via UPHCC-usb) LCD controller board that can handle a wide variety of graphical and character dot-matrix Liquid Crystal Displays (LCD). It is possible to connect several different display types to the board at the same time. The UPHCC-lcd can drive 4 (under certain circumstances up to 12) seperate displays at the same time. This makes it easy to "mix-and-match" LCD types on one controller. UPHCC-lcd features 4 software-dimmable LED backlight drivers.
