◆ ulink_calculate_delay()

static int ulink_calculate_delay	(	enum ulink_delay_type	type,
		long	f,
		int *	delay
	)

static

Calculate delay values for a given TCK frequency.

The OpenULINK firmware uses five different speed values for different commands. These speed values are calculated in these functions.

The five different commands which support variable TCK frequency are implemented twice in the firmware:

Maximum possible frequency without any artificial delay
Variable frequency with artificial linear delay loop

To set the ULINK to maximum frequency, it is only necessary to use the corresponding command IDs. To set the ULINK to a lower frequency, the delay loop top values have to be calculated first. Then, a CMD_CONFIGURE_TCK_FREQ command needs to be sent to the ULINK device.

The delay values are described by linear equations: t = k * x + d (t = period, k = constant, x = delay value, d = constant)

Thus, the delay can be calculated as in the following equation: x = (t - d) / k

The constants in these equations have been determined and validated by measuring the frequency resulting from different delay values.

Parameters

type	for which command to calculate the delay value.
f	TCK frequency for which to calculate the delay value in Hz.
delay	where to store resulting delay value.

Returns: on success: ERROR_OK; on failure: ERROR_FAIL

◆ ulink_calculate_frequency()

static long ulink_calculate_frequency	(	enum ulink_delay_type	type,
		int	delay
	)

static

Calculate frequency for a given delay value.

Similar to the ulink_calculate_delay function, this function calculates the TCK frequency for a given delay value by using linear equations of the form: t = k * x + d (t = period, k = constant, x = delay value, d = constant)

Parameters

type	for which command to calculate the delay value.
delay	delay value for which to calculate the resulting TCK frequency.

Returns: the resulting TCK frequency

◆ ulink_execute_queue()

static int ulink_execute_queue ( void )
