Overview
The Digilent PmodCLS is a 16x2 character LCD module driven by an Atmel®
The PmodCLS.

Functional Description
The PmodCLS module can be used to display important information during program development or as a user
interface after the project has been completed. The module is ideally suited for microcontroller boards but can
also be used in projects using a FPGA board.
The module is capable of executing a variety of instructions such as erasing specific characters, setting different
display modes, scrolling, and displaying user-defined characters. These instructions are specified using escape
sequences to send commands to the board's embedded Atmel ATmega48 microcontroller. The display on the
module is driven by this AVR and controls all of the features of the board.
