GETTING STARTED
The MCP23X17 Evaluation Board is a fully functional, assembled and tested board for
evaluation of the MCP23017 (I
purpose I/O expanders. The following describes the basic setup and operation (see
Figure 2-1):
1. Either connect a 9V power supply into the power jack (J2) or connect a 5V power
2. The green power LED will illuminate.
3. The device selector slide switch selects between the two devices. Slide the
4. On power-up, the LEDs will sequence in a slow scroll pattern.
5. Press a button and the LED sequencing will match the function defined by the
