Function Documentation

int IRTVGet

(

void

)

Waits for IR input and returns the keycode.

Returns

int retVal : Next code from the buffer

0 = no key

int IRTVGetStatus

(

void

)

Checks to see if IR input is enabled;.

Returns

int retVal: whether IR input is enabled

-0: not enabled
-1: enabled

int IRTVInit

(

int

semantics

)

Initializes the IR remote control decoder by calling IRTVInit() with the device name found in the corresponding HDT entry.

Parameters

DeviceSemantics

semantics, for the IR remote this will be the controller code

Returns

int retVal :

• 0 = ok
• 1 = HDT file error
• 2 = invalid or missing "IRTV" HDT entry for this semantics
• 3 = unable to initialise IR input

void IRTVSetHoldDelay

(

int

delay

)

sets the hold to prevent multiple presses being registered when a IR remote button is pressed

Parameters

int	delay: the value to set the delay to, larger value equal larger delay
