Description
General part information
MCP23X17 Series
The MCP23X17EV is a MCP23X17 16bit GPIO expander evaluation board, demonstrates simple input/output functionality of the MCP23017 I2C interface and the MCP23S17 SPI interface. Both the devices are connected to the same inputs and outputs and selector switch is used to select which device the PICmicro controls. A mux is used to route the serial (I2C or SPI) from the PICmicro to the MCP23X17. Four MCP23X17 pins are configured as inputs and connected to four momentary push buttons. The remaining twelve GPIO pins are configured as outputs and connected to LEDs. Each button causes the LEDs to sequence in a predetermined pattern. The MCP23X17 is provided in small, space saving 18 lead SSOP packages.
