Detailed Description

The LED NTSC implementation of the pulse driver interface.

This implementation requires an LED light to be attached to the digital GPIO pin. The pulses emitted adhere to the NTSC protocol, which is required to communicate with R.O.B.

Member Function Documentation

init()

nes::rob::error_code LedNtscDriver::init ( void *  reserved = nullptr )

overridevirtual

Initialize the pulse driver.

Performs necessary operations to initialize the pulse driver implementation.

Parameters

[in,out]

reserved

Supports driver specific initialization parameters

Returns

an nes::rob::error_code describing errors encountered during processing

Return values

nes::rob::pulse_driver_error::success	No errors encountered during processing.
nes::rob::pulse_driver_error::hal_init	A HAL error occured during the pulse driver initialization.

Implements nes::rob::PulseDriver.

pulse()

nes::rob::error_code LedNtscDriver::pulse ( void *  reserved = nullptr ) const

overridevirtual

Generate a protocol specific pulse.

Performs necessary GPIO operations to generate a protocol compatible pulse.

Parameters

[in,out]

reserved

Supports driver specific implementation parameters

Returns

an nes::rob::error_code describing errors encountered during processing

Return values

nes::rob::pulse_driver_error::success	No errors encountered during processing.

Implements nes::rob::PulseDriver.

rest()

nes::rob::error_code LedNtscDriver::rest ( void *  reserved = nullptr ) const

overridevirtual

Generate a protocol specified rest period.

Places GPIO in resting state and awaits a period defined by the protocol.

Parameters

[in,out]

reserved
