SAMPLE DEVICE I/O FEATURES AND CONNECTIONS
LEDs
A.1.13
An LCD display with two lines, 16 characters each, is connected to the SPI I/O
expander, MCP23S17. The two control lines and eight data lines are connected to the
I/O expander.
The I/O expander has an SPI interface that connects it to the microcontroller.The I/O
expander is disabled or enabled from the SPI by jumper JP3.
A.1.14
A sample part programmed with a simple program is included in the PICDEM PIC18
Explorer Demonstration Board Kit. The devices’ I/O features and port connections are
listed in Table A-1.
