Detailed Description

template<typename MANAGER>
class devices::mcp230xx::MCP23008< MANAGER >::ConfigureGPIOFuture

Create a future to be used by asynchronous method configure_gpio(ConfigureGPIOFuture&).

This is used by configure_gpio() to asynchronously launch the I2C transaction, and it shall be used by the caller to determine when the I2C transaction is finished.

Parameters

direction	each bit sets the direction of one pin of the port; `1` means Input, `0` means Output.
pullup	each bit (only for input pins) sets if a pullup resistor shall be internally connected to the pin; if `1`, a pullup is added, if `0`, no pullup is added.
polarity	each bit (only for input pins) let you invert polarity of the matching input pin; if `1`, polarity is inverted, ie one the level on the input pin is `0`, then it is read as `1`, and conversely.
