LCD Interface

A 16x2 LCD display is available as an option for the SX-560-6900 Evaluation Daughtercard. This LCD can be controlled from either Serial Port 2 or via the SPI interface. The LCD display plugs into header JP1. Header JP12 is used to select serial or SPI control (place a jumper on pins 1 and 2 to select serial, or place the jumper on pins 2 and 3 to select SPI).
