 32bit GPIO Expander Shield

The GPIO expander shield provides the Anarduino Mini with an extra 32bits of GPIO. Each GPIO pin is configured via software as an input or outputā??configured as 4 banks of 8-bit GPIO. Control of the GPIO's is facilitated via the MicroController I2C interface, and it leverages the functionality of the PCA9538A I2C to parallel interface IC. It also provides interrupt capability for generating a processor interrupt on data pattern changes.
