In this section, let's do a quick and easy recipe with BoneScript, one that turns on and off the on board LEDs, also known as USR LEDs. We will tackle more complex recipes with BoneScript in the next chapter.

How to do it...

In order to do this, perform the following steps:

  1. Remove all cables and power from your BBB.

  2. Power up your board via the mini USB using your desktop USB port.

  3. On the BEAGLEBONE_BLACK device that appears on your desktop, browse to and open the START.htm file (some versions of the OS may have a slightly different file name, such as BASIC_START.htm).

    Note

    Note that on Debian 8 (Jessie), your board will be labelled BEAGLEBONE on the desktop and not BEAGLEBONE_BLACK.

  4. Scroll down the page to BoneScript interactive guide, where you'll see an embedded script that you can run to interact with BBB.
