Detailed Description

Device-specific functionality for the Topaz devices

Device details:

• ARMv7.
• Turbo mode from 40% to 95% of speed.
• Switches (2): headphones inserted and power.
• Raw orientation readings are rotated +90 degrees from correct orientation before being translated.
• Home button wakes up the screen.

Constructor & Destructor Documentation

HostArmTopaz::HostArmTopaz

(

)

Constructs a Topaz device host

HostArmTopaz::~HostArmTopaz ( )

virtual

Destroys a Topaz device host

Member Function Documentation

int HostArmTopaz::getNumberOfSwitches ( ) const

virtual

Gets the number of hardware switches the current host device has

As an example, the Palm Pre has 3 switches:

• Ringer on/off.
• Slider opened/closed.
• Headphones inserted/no headphones.

Returns

Number of hardware switches the device has.

Reimplemented from HostArm.

const char * HostArmTopaz::hardwareName ( ) const

virtual

Reimplemented from HostArm.

bool HostArmTopaz::homeButtonWakesUpScreen ( )

virtual

Presumably whether the Home button wakes up the screen

This is seldom used and largely undocumented. Description is more or less a guess.

Todo:

Determine with certainty what this method is for.

Returns

Presumably true if pressing the Home button wakes up the screen and false otherwise.

Reimplemented from HostBase.

OrientationEvent * HostArmTopaz::postProcessDeviceOrientation ( OrientationEvent *  currOrientation )

virtual

For Topaz, the orientation events are rotated by +90 relative to the display orientation. For Topaz Screen up = Left Orientation

Following is the actual screen (Frame Buffer) orientation

  Left(90)
-----------
|         |
|         |

UP | | Down (180) 0 | |

| |

o <- home button

Right(270/-90)

But, Nyx gives us data 270 rotated clock-wise (-90 anti clock-wise)

        Up
    -----------
    |         |
    |         |

Right | | Left | |

| |

o <- home button

Down

Reimplemented from HostBase.

void HostArmTopaz::turboMode ( bool  enable )

protectedvirtual

Enables/disables turbo mode

Changes CPU frequency scaling. When turbo mode is enabled, the CPU is set to run at full speed. When disabled, it turns the speed down to save on power usage.

Parameters

enable

true to enable turbo mode, false to disable it

Reimplemented from HostBase.
