Types

type Device

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

Device represents a device connected to the GPIB.

func Open

func Open(board, pad, sad int, opts *Options) (*Device, error)

Open will open a provided GPIB device.

func (*Device) Close

func (d *Device) Close() error

Close will release the underlying handle to the GPIB device, and close the related context, terminating any spawned helpers.

func (*Device) Local

func (d *Device) Local() error

Local will return local control to the user over the device.

func (*Device) Read

func (d *Device) Read(buf []byte) (int, error)

Read will read data from the GPIB device.

func (*Device) Write

func (d *Device) Write(buf []byte) (int, error)

Write will write user data to the GPIB device.

type Options

type Options struct {
	// BaseContext will be used to extend a context with the same lifecycle
	// as the underlying handle to the remote GPIB device.
	BaseContext context.Context
}

Options contains configurable aspects of the connected GPIB device.
