Detailed Description

class getting LTH (Low To High) and HTL (High To Low) transitions in logic_input

Constructor & Destructor Documentation

transition::transition	(	logic_input *	data = NULL,
		uint8_t	pin_clock = 1,
		activity *	cs = NULL
	)

Constructor.

Calls init() if data is not NULL.

Member Function Documentation

int transition::Draw

(

mglGraph *

gr

)

Draw statistics on period transitions.

Parameters

gr	pointer to a mglData object

int transition::Draw	(	mglGraph *	gr,
		char	sign,
		uint8_t	subplot
	)

Draw vertical arrows at same times as transitions.

Parameters

gr	pointer to a mglGraph object.
sign	sign of the transition: \'u\' for getting stats about LTH transitions. \'d\' for getting stats about HTL transitions.
subplot	subplot index where to draw.

void transition::find_transition	(	logic_input *	data,
		char	sign = 'u'
	)

find the transitions from a logic_input object

Parameters

data	logic_input source.
sign	sign of the transition: \'u\' for getting stats about LTH transitions. \'d\' for getting stats about HTL transitions.

float transition::GetStats	(	activity *	cs,
		char	sign = 'u'
	)

Get statistics on transition period (min, average and max)

Parameters

cs	pointer to an activity. Inactive periods are discarded.
sign	sign of the transition: \'u\' for getting stats about LTH transitions. \'d\' for getting stats about HTL transitions.

void transition::init	(	logic_input *	data,
		uint8_t	pin_clock,
		activity *	cs = NULL
	)

Initialization.

Parameters

data	logic_input source. if not NULL call find_transition().
pin_clock	index of the pin of the clock
cs	pointer to activity. If not NULL GetStats() is called.
