Detailed Description

An implementation of IDisplay for TFT color displays.

Constructor & Destructor Documentation

TFTDisplay()

TFTDisplay::TFTDisplay ( TFTDriver & driver )

explicit

Creates a TFT display for a specific TFT driver.

Parameters

driver

The underlying driver.

Member Function Documentation

determineLayout()

void TFTDisplay::determineLayout ( )

private

Pre-computes the positions of UI elements.

initialize()

void TFTDisplay::initialize ( )

overridevirtual

In general, must be called before any calls to update.

Implements IDisplay.

update()

void TFTDisplay::update ( float channel1Power, float channel2Power )

overridevirtual

Update the display with all relevant values.

Parameters

channel1Power	The output duty cycle for channel 1 (between 0 and 1)
channel2Power	The output duty cycle for channel 2 (between 0 and 1)

Implements IDisplay.
