Constructor & Destructor Documentation

TM1638liteI2C()

TM1638liteI2C::TM1638liteI2C

(

I2Cwrapper *

w

)

Constructor.

Parameters

w	Wrapper object representing the target a TM1638 is connected to.

Member Function Documentation

attach()

void TM1638liteI2C::attach	(	uint8_t	strobe,
		uint8_t	clock,
		uint8_t	data
	)

Replaces the TM1638lite constructor and takes the same arguments. Will allocate an TM1638lite object on the target's side and make it ready for use. Check myNum >= 0 to see if the target successfully added the object. If not, it's -1.

Parameters

strobe,clock,data

See original library

Note

The target's platform pin names might not be known to the controller's platform, if both are different. So it is safer to use integer equivalents as defined in the respective platform's pins_arduino.h

displayASCII()

void TM1638liteI2C::displayASCII	(	uint8_t	position,
		uint8_t	ascii
	)

displayHex()

void TM1638liteI2C::displayHex	(	uint8_t	position,
		uint8_t	hex
	)

displaySS()

void TM1638liteI2C::displaySS	(	uint8_t	position,
		uint8_t	value
	)

displayText()

void TM1638liteI2C::displayText

(

String

text

)

Note

: displayText() is implemented locally at the controller's side to avoid having to send arbitrary long strings. This happens transparently for the caller and might only lead to problems if the original library's code changes.

readButtons()

uint8_t TM1638liteI2C::readButtons

(

)

reset()

void TM1638liteI2C::reset

(

)

sendCommand()

void TM1638liteI2C::sendCommand

(

uint8_t

value

)

setLED()

void TM1638liteI2C::setLED	(	uint8_t	position,
		uint8_t	value
	)
