Detailed Description

Class doing acquisition from RPI's GPIO.

Constructor & Destructor Documentation

logic_input::logic_input	(	uint8_t	npin = 0,
		uint8_t *	pins = NULL,
		uint32_t	npoint = 0,
		float	delay = 0
	)

Constructor.

Call init_acquisition and acquire if the corresponding parameters are set.

Member Function Documentation

void logic_input::acquire	(	uint32_t	npoint = 0,
		float	delay = 0
	)

Start the acquisition.

Parameters

npoint	number of logic values to acquire (1 point is 2 GPIO measurements: one with pull up and one with pull down).
delay	time in ms to wait between 2 point acquisition.

int logic_input::Draw	(	mglGraph *	gr,
		const char *	label[] = NULL,
		uint8_t	pin_stats = 0
	)

Plot logic values acquired.

Parameters

gr	pointer to a mglGraph object
label	array of strings giving label of each pin.
pin_stats	subplot where to print stats about acquisition.

void logic_input::init_acquisition	(	uint8_t *	pins,
		uint8_t	npin = 0
	)

Initialisation of the object for the capture.

Parameters

pins	array of the GPIO pin numbers (ex {9,10} for GPIO9 and GPIO10) to be used during acquisition.
npin	number of pins to be used during acquisition. Max value is pins array size.

void logic_input::Load

(

const char *

filename

)

Load the object into a file.

Parameters

filename

string contenaning filename to be loaded.

const void logic_input::Save

(

const char *

filename

)

Save the object into a file.

Parameters

filename

string contenaning filename to be saved.

Member Data Documentation

mglData* logic_input::rawdata

Array of mglData vector.

Size of the array is npin, each vector contains the npoint logic value measurements for the co responding pin

mglData logic_input::t

mglData vector of the time of each acquisition.

contains npoint acquisition time in s.
