Description: The experimental box with built-in LCD controller for the SED1520, lattice is 122 × 32, needs two SED1520 formed by the E1, E2, respectively gating to control the display of about two and a half screen. Graphic LCD module has two connections, one for the direct access method, an indirect access. In this study the direct control mode. Direct control method is to interface LCD module as memory or I/O devices directly linked to the computer bus. Computer controlled by address decoder strobe E1 and E2 read/write signal R/W control the address lines A1, command/data register select control signal from the address line A0.
