Abstractions used to configure the MAX7301 hardware.
| Configurator | A Configurator provides methods to build a list of device configuration changes, such as port
modes and device configuration bits, and commit them to the device. You obtain one from the
Expander::configure(), chain method calls on it to make configuration changes, and then end
the chain with commit() to transmit them to the MAX7301.
|
| PortMode | A PortMode enumerates the three supported modes that each GPIO pin on the MAX7301 may be
configured to.
