AVMCECInit()

BOOL AVMCECInit

(

void

)

Initializes CEC.

Returns

TRUE on success.

AVMEnableCEC()

void AVMEnableCEC

(

void

)

Enable CEC.

AVMCECSendCommand()

BOOL AVMCECSendCommand	(	TVECECLogicalAddress	destination,
		TVECECOpCode	opCode,
		uint8_t *	parameters,
		uint8_t	numParameters
	)

Sends a CEC command.

Parameters

destination	Logical address of the device where the command should be sent to.
opCode	The op code of the command to send.
parameters	Pointer to optional command parameters.
numParameters	The amount of additional parameters.

Returns

TRUE on success.

AVMCECReceiveCommand()

BOOL AVMCECReceiveCommand	(	TVECECLogicalAddress *	outInitiator,
		TVECECOpCode *	outOpCode,
		uint8_t *	outParameters,
		uint8_t *	outNumParameters
	)

Get the last receieved CEC command.

Parameters

outInitiator	Pointer to store the logical address of the initiator of the command to.
outOpCode	Pointer to store the op code of the command to.
outParameters	Pointer to store additional parameters to.
numParameters	Pointer to store the amount of additional parameters to.

Returns

TRUE on success.

Warning

This will return success even if no new command has been receieved. The caller should check that the parameters were actually written to.
