Member Function Documentation

brightness()

void TM1638plus_common::brightness

(

uint8_t

brightness

)

Sets the brightness level of segments in display on a scale of brightness.

Parameters

brightness

byte with value 0 to 7 The DEFAULT_BRIGHTNESS = 0x02

displayBegin()

void TM1638plus_common::displayBegin

(

)

Begin method , sets pin modes and activate display.

Note

Call in Setup() loop

HighFreqshiftin()

uint8_t TM1638plus_common::HighFreqshiftin ( uint8_t  dataPin, uint8_t  clockPin, uint8_t  bitOrder  )

protected

Shifts in a byte of data from the Tm1638 SPI-like bus.

Parameters

dataPin	Tm1638 Data GPIO
clockPin	Tm1638 Clock GPIO
bitOrder	Data byte bit order LSBFIRST OR MSBFIRST, Set to LSBFIRST for Tm1638

Returns

Data byte

Note

Used instead of arduino function "shiftin" when _HIGH_FREQ is set to true, for high frequency CPU's

HighFreqshiftOut()

void TM1638plus_common::HighFreqshiftOut ( uint8_t  dataPin, uint8_t  clockPin, uint8_t  bitOrder, uint8_t  val  )

protected

Shifts out a byte of data on to the Tm1638 SPI-like bus.

Parameters

dataPin	Tm1638 Data GPIO
clockPin	Tm1638 Clock GPIO
bitOrder	Data byte bit order LSBFIRST OR MSBFIRST, Set to LSBFIRST for Tm1638
val	The byte of data to shift out

Note

Used instead of arduino function "shiftOut" when _HIGH_FREQ is set to true, for high frequency CPU's Font Data Table , map of ASCII values/table to 7-segment, offset to position 32.

reset()

void TM1638plus_common::reset

(

void

)

Reset / clear the display.

Note

The display is cleared by writing zero to all data segment addresses.

sendCommand()

void TM1638plus_common::sendCommand ( uint8_t  value )

protected

Send command to display.

Parameters

value

command byte to send

sendData()

void TM1638plus_common::sendData ( uint8_t  data )

protected

Send Data to display.

Parameters

data	Data byte to send
