Constructor & Destructor Documentation

TwiI2c()

TwiI2c::TwiI2c ( uint8_t  sa = 0x00 )

explicit

Creates I2C instance for AVR controllers. Can be used for command compilation with plain avrgcc

Parameters

sa	i2c address of device to control

Member Function Documentation

begin()

void TwiI2c::begin

(

)

Initializes i2c interface

end()

void TwiI2c::end

(

)

Closes i2c interface

send()

void TwiI2c::send

(

uint8_t

data

)

Sends byte to SSD1306 device

Parameters

data	- byte to send

sendBuffer()

void TwiI2c::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 TwiI2c::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 93 of file i2c_twi.h.

start()

void TwiI2c::start

(

)

Starts communication with SSD1306 display.

stop()

void TwiI2c::stop

(

)

Ends communication with SSD1306 display.
