GPIO Expander (16-Bit) Evaluation Board
The MCP23X17 Evaluation Board demonstrates simple input/output functionality of the MCP23017 (I2C interface) and the MCP23S17 (SPI interface). The system demonstrates the simplicity of monitoring four pins configured as inputs and applying a predetermined pattern on LEDs connected to the remaining 12 pins configured as outputs.
