Function Documentation

TMR_Status TMR_TF_init_gen2_select	(	TMR_TagFilter *	filter,
		bool	invert,
		TMR_GEN2_Bank	bank,
		uint32_t	bitPointer,
		uint16_t	maskBitLength,
		uint8_t *	mask
	)

Initialize a TMR_Filter structure as a Gen2 select filter with the provided parameters.

Parameters:

	filter	Pointer to the filter structure to initialize
	invert	Whether to invert the result of the select
	bank	The memory bank on the tag to compare with the data
	bitPointer	The bit address of the tag data to compare
	maskBitLength	The length of the data to compare
	mask	The data to compare

TMR_Status TMR_TF_init_tag	(	TMR_TagFilter *	filter,
		TMR_TagData *	tag
	)

Initialize a TMR_Filter structure as tag data (EPC) filter with the provided tag (which is copied).

Parameters:

	filter	Pointer to the filter structure to initialize
	tag	TMR_TagData to use as the filter value

bool TMR_TF_match	(	TMR_TagFilter *	filter,
		TMR_TagData *	tag
	)

Test if a tag matches this filter. Only applies to selects based on the EPC.

Parameters:

	filter	The filter to test with.
	tag	The tag to test.

Returns:

true if the tag matches the filter.
