Detailed Description

Implementation of the LedDevice interface for writing to pi-blaster based PWM LEDs.

Constructor & Destructor Documentation

LedDevicePiBlaster::LedDevicePiBlaster ( const QJsonObject & deviceConfig )

Constructs specific LedDevice.

Parameters

deviceConfig json device config

bool LedDevicePiBlaster::init ( const QJsonObject & deviceConfig )

virtual

Sets configuration.

Parameters

deviceConfig the json device config

Reimplemented from LedDevice.

int LedDevicePiBlaster::open ( )

virtual

Attempts to open the piblaster-device.

This will only succeed if the device is not yet open and the device is available.

Reimplemented from LedDevice.
