INTRODUCTION
WHAT IS THE GPIO EXPANDER KEYPAD AND LCD DEMO BOARD?
WHAT THE GPIO EXPANDER KEYPAD AND LCD DEMO BOARD KIT
INCLUDES
This chapter provides an overview of the GPIO Expander Keypad and LCD Demo
Board and covers the following topics:
• What is the GPIO Expander Keypad and LCD Demo Board?
• What the GPIO Expander Keypad and LCD Demo Board Kit includes
The GPIO Expander Keypad and LCD Demo Board allows the system designer to
evaluate the operation of the MCP23X17 and MCP23X08 General Purpose I/O (GPIO)
Expanders. The board demonstrates the GPIO Expanders’ performance in a keypad
and LCD example.
