Detailed Description

GPIO output-only wrapper with output configuration and drive strength.

This class owns an output pin configuration and exposes Write()/Toggle(). Output configuration includes output type (push-pull vs. open-drain), pull mode, drive strength, and the initial output state.

Constructor & Destructor Documentation

GpioOut() [1/2]

c7222::GpioOut::GpioOut ( uint32_t  pin )

inlineexplicit

Create a GPIO output with default configuration.

~GpioOut()

virtual c7222::GpioOut::~GpioOut ( )

virtual

Destructor.

Platform backends may use this to unregister the pin from internal maps.

GpioOut() [2/2]

c7222::GpioOut::GpioOut ( uint32_t  pin, const Config &  config  )

explicit

Create a GPIO output with the given configuration.

Parameters

pin	GPIO number.
config	Initial configuration.
