Constructor & Destructor Documentation

AvrSpi()

AvrSpi::AvrSpi ( int8_t  csPin, int8_t  dcPin, uint32_t  frequency  )

explicit

Creates AVR spi instance. This interface can be used from command line avrgcc toolchain.

Parameters

csPin	pin to enable chip select signal, or -1 if cs pin is not required.
dcPin	pin to control data/command mode.
frequency	frequency in HZ to run SPI bus.

(

)

Initializes spi interface

end()

void AvrSpi::end

(

)

Closes spi interface

send()

void AvrSpi::send

(

uint8_t

data

)

Sends byte to SSD1306 device

Parameters

data	- byte to send

sendBuffer()

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

Sends bytes to SSD1306 device.

Parameters

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

start()

void AvrSpi::start

(

)

Starts communication with SSD1306 display.

stop()

void AvrSpi::stop

(

)

Ends communication with SSD1306 display.
