Constructor & Destructor Documentation

ArduinoI2c()

ArduinoI2c::ArduinoI2c ( int8_t  scl = -1, int8_t  sda = -1, uint8_t  sa = 0x00  )

explicit

Creates i2c implementation instance for Arduino platform.

Parameters

scl	clock pin to use for i2c
sda	data pin to use for i2c
sa	i2c address of the device to control over i2c

Member Function Documentation

begin()

void ArduinoI2c::begin

(

)

Initializes i2c interface

end()

void ArduinoI2c::end

(

)

Closes i2c interface

send()

void ArduinoI2c::send

(

uint8_t

data

)

Sends byte to SSD1306 device

Parameters

data	- byte to send

sendBuffer()

void ArduinoI2c::sendBuffer	(	const uint8_t *	buffer,
		uint16_t	size
	)

Sends bytes to SSD1306 device.

Sends bytes to SSD1306 device. This functions gives ~ 30% performance increase than ssd1306_intf.send.

Parameters

buffer	- bytes to send
size	- number of bytes to send

setAddr()

void ArduinoI2c::setAddr ( uint8_t  addr )

inline

Sets i2c address for communication This API is required for some led displays having multiple i2c addresses for different types of data.

Parameters

addr	i2c address to set (7 bits)

Definition at line 91 of file arduino_wire.h.

start()

void ArduinoI2c::start

(

)

Starts communication with SSD1306 display.

stop()

void ArduinoI2c::stop

(

)

Ends communication with SSD1306 display.
