Detailed Description

Really tiny library to basic 7 segments displays.

7 segment displays directly controlled from microcontroller

Common anode and common cathode allowed

Uses multiplexed displays for driving as much displays as it can with minimum pins.

Library depends on uTimerLib library, https://github.com/Naguissa/uTimerLib

Constructor & Destructor Documentation

uSevenSegmentLib()

uSevenSegmentLib::uSevenSegmentLib	(	const unsigned char	displays,
		int	pins[8],
		int *	muxes,
		unsigned int	freq = 40,
		bool	common_anode = false
	)

Constructor.

Parameters

displays	Number of displays
pins	array of pins {a, b, c, d, e, f, g, dot}
muxes	array of common pin for each display
freq	Optional. Refresh frequency (for all digits, will be multiplied by digits to calculate end result)
common_anode	Optional. Set true to change to common_anode displays

Member Function Documentation

attachInterrupt()

void uSevenSegmentLib::attachInterrupt

(

)

Attach timer interrupt.

Needed for usual operation, but you can call loop manually instead

get()

long int uSevenSegmentLib::get

(

)

Gets stored number.

Returns

number in memory

interrupt()

void uSevenSegmentLib::interrupt ( void  )

static

Main public interrupt loop.

Calls private loop

set()

void uSevenSegmentLib::set

(

long int

number

)

Sets a number to all displays.

Parameters

number

to be setted

zeroFill()

void uSevenSegmentLib::zeroFill

(

bool

zf

)

Sets Zerofill on/off.

When enabled all leading digits are light as zero.

Parameters

bool	zf If true, leading zeros will be displayed
