virtual	~I2CInterface ()

virtual void	begin ()
	Initialize the I2C bus.

virtual void	writeRegister (uint8_t addr, uint8_t reg, uint8_t val)=0
	Write one byte to a device register.

Detailed Description

Abstract I2C bus interface.

Decouples MCP23017Driver from any specific I2C implementation so the same driver code compiles and tests on both Arduino targets and host machines.

Constructor & Destructor Documentation

virtual I2CInterface::~I2CInterface ( )

inlinevirtual

virtual void I2CInterface::begin ( )

inlinevirtual

Initialize the I2C bus.

Default no-op: safe for mock objects or buses started elsewhere. WireI2C overrides this to call Wire.begin().

Reimplemented in WireI2C.

virtual void I2CInterface::writeRegister	(	uint8_t	addr,
		uint8_t	reg,
		uint8_t	val
	)

pure virtual

Write one byte to a device register.

Parameters

[in]	addr	7-bit I2C device address.
[in]	reg	Register index within the device.
[in]	val	Byte value to write.

Implemented in WireI2C.
