In order to minimize the amount of wire used, I am going to use the 4-bit operation method. The higher nibble of the LCM (LCD Module) is connected to the upper nibble of PORTB. Controlling LCD Module using PIC Microcontrollers The Read/Write(R/W'), Enable(E) & Register Select(RS) pins are connected as shown in the schematic. The R/W' pin can be tied permanently to ground only if writing to the LCM, to save 1 I/O pin. | Home | Top Page | Contact | Copyright Notice: This article, including all text, documents and schematic diagrams, are the intellectual property of Vincent Wong, and is Copyright (c) 2005.
