Detailed Description

Output-only PWM wrapper with period and duty configuration.

This class provides a minimal PWM interface:

• Period in microseconds
• Duty cycle as a fraction [0.0, 1.0]

Platform backends map this to the underlying PWM hardware and enforce single ownership per GPIO pin.

Constructor & Destructor Documentation

PwmOut() [1/2]

c7222::PwmOut::PwmOut ( uint32_t  pin )

explicit

Create a PWM output with default configuration.

PwmOut() [2/2]

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

explicit

Create a PWM output with the given configuration.

Parameters

pin	GPIO number.
config	Initial configuration.

~PwmOut()

virtual c7222::PwmOut::~PwmOut ( )

virtual

Destructor.

Platform backends may unregister pin ownership here.
