Detailed Description

Class implements SPI support for Arduino platforms

Definition at line 38 of file arduino_spi.h.

Constructor & Destructor Documentation

ArduinoSpi()

ArduinoSpi::ArduinoSpi ( int8_t  csPin = -1, int8_t  dcPin = -1, int8_t  clkPin = -1, int8_t  mosiPin = -1, uint32_t  freq = 0, SPIClass *  spi = &SPI  )

explicit

Creates instance of spi implementation for Arduino platform.

Parameters

csPin	chip select pin to use, -1 if not required
dcPin	data command pin to use
clkPin	clk pin to use, -1 to use default. Doesn't work on all controllers
mosiPin	mosi pin to use, -1 to use default. Doesn't work on all controllers
freq	frequency in HZ to run spi bus at

begin()

void ArduinoSpi::begin

(

)

Initializes spi interface

end()

void ArduinoSpi::end

(

)

Closes spi interface

send()

void ArduinoSpi::send

(

uint8_t

data

)

Sends byte to SSD1306 device

Parameters

data	- byte to send

sendBuffer()

void ArduinoSpi::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

start()

void ArduinoSpi::start

(

)

Starts communication with SSD1306 display.

stop()

void ArduinoSpi::stop

(

)

Ends communication with SSD1306 display.
