An app note on interfacing liquid-crystal displays (LCDs):
Teridian’s single- and 3-phase energy-meter ICs have a variety of interfacing ports for data access and information display. This application note provides details on interfacing liquid-crystal displays (LCDs) to the 71M6511, 71M6511H, 71M6513, and 71M6515H devices. These details are relevant to 71M6511, 71M6513, 71M6515H demo boards with Varitronix VIM-808 mono LCDs, but the general rules apply to all static and multiplexed LCDs. The article also details the LCD routines used in the demo board firmware.
