Constructor & Destructor Documentation

LinuxI2c()

LinuxI2c::LinuxI2c ( int8_t  busId = -1, uint8_t  sa = 0x00  )

explicit

Creates instance of I2C implementation for Linux (via i2cdev)

Parameters

busId	i2c bus number, if -1 defaults to 1
sa	i2c address of the display (7 bits)

Member Function Documentation

send()

void LinuxI2c::send

(

uint8_t

data

)

Sends byte to SSD1306 device.

Parameters

data	- byte to send

sendBuffer()

void LinuxI2c::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 LinuxI2c::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)
