Types

type I2C

type I2C struct {
	// contains filtered or unexported fields
}

I2C defines an I2C type to read and write from/to registers.

func NewI2C

func NewI2C(bus string, addr uint16) (*I2C, error)

NewI2C returns a new I2C interface at the specified bus and address. If `bus` is set to "", the first available bus is used. The address must always be specified.

func (*I2C) Close

func (i *I2C) Close()

Close closes the bus used by I2C.

func (*I2C) Read

func (i *I2C) Read(reg byte) (byte, error)

Read reads a single byte from a register.

func (*I2C) ReadBytes

func (i *I2C) ReadBytes(reg byte, n int) ([]byte, error)

ReadBytes reads n bytes from a register.

func (*I2C) Write

func (i *I2C) Write(reg byte, data ...byte) error

Write writes a byte or bytes to a register.
