2.2 Available Interfaces

The ability to use each interface is dependent on OS and what libraries were available during the toolkit install.

To verify the available interfaces, run the following command in octave:

instrhwinfo

The function will return information on the supported interfaces that are available, similar to below:

    ToolboxVersion = 0.7.0
    ToolboxName = octave instrument control package
    SupportedInterfaces =
    {
      [1,1] = gpib
      [1,2] = i2c
      [1,3] = parallel
      [1,4] = serial
      [1,5] = serialport
      [1,6] = tcp
      [1,7] = tcpclient
      [1,8] = udp
      [1,9] = udpport
      [1,10] = usbtmc
      [1,11] = vxi11
    }

Most interfaces have two types of functions:

• somewhat compatible matlab functions such as fread, fwrite
• interface specific lower level functions such as udp_read, udp_write
