Detailed Description

Class containing bits information obtained from logic_input and [transition](transition).

Constructor & Destructor Documentation

binary::binary	(	const binary &	source,
		uint32_t	index_start = 0,
		uint32_t	index_end = 0
	)

Default copy constructor, it allows to select a sub-range of the source object.

Parameters

source	source binary object
index_start	inclusive index to start copy from
index_end	inclusive index where to stop the copy. If index_end=0 or omitted, copy 1 bit only.

binary::binary	(	const binary &	source,
		float	t_start,
		float	t_end = 0
	)

Copy constructor allowing to select a sub-range in time of the source object.

Parameters

source	source binary object
t_start	time to start copy from
t_end	time when to stop the copy. If t_end=0 or omitted, copy until the end.

Member Function Documentation

int binary::Draw

(

mglGraph *

gr

)

Display each bit value.

Parameters

gr	pointer to mglGraph object

Returns

execution status (0 if OK)

uint32_t binary::Get	(	uint32_t	index_start,
		uint32_t	index_end = 0
	)

Return an uint32_t the value between inclusive bits index_start and index_end (as most significant bit first).

Parameters

index_start	first bit to read (inclusive).
index_end	last bit to read (inclusive). If index_end=0 or omitted, only 1 bit is read.

Returns

value between inclusive bits index_start and index_end (as most significant bit first).

uint32_t binary::Get_nbad	(	uint32_t	index_start,
		uint32_t	index_end = 0
	)

Return bad reading number on an interval.

Parameters

index_start	inclusive index to start looking for bad readings.
index_end	inclusive index to stop looking for bad readings.

Returns

bad reading number (number of HIGHR or ERR bits).

void binary::init	(	logic_input *	data,
		transition *	clk,
		uint8_t	pin,
		char	transition_direction = 'u'
	)

Initialize from an logic_input object data.

binary values are got from data at pin pin, when the specified transition occurs.

Parameters

data	pointer to the logic_input object
clk	pointer to the transition object
pin	index of the data where to find binary values
transition_direction	'u' for low to high transitions, 'd' for the high to low transitions

void binary::sprint	(	char	value[2],
		uint32_t	bit
	)

Copy the logic value of a bit in string.

Parameters

value	2 chars receiving the logic value: "0" for low voltage (<1V when pull up and down used). "1" for high voltage (>2V when pull up and down used). " " for high resistance (<1V when pull down and >2V when pull up) "E" for error (>2V when pull down and <1V when pull up). Abnormal state due to a transition between both measurements. "?" error from the software, report if seen.
bit	index of the bit

Member Data Documentation

uint8_t binary::npin

number of pins used for acquisition

used to know the number of subplots

uint8_t binary::pin

pin where the binary data has been captured

it is the subplot where the binary data will be
