Summary
In the first part of this chapter, we built our development system and configured the Cloud9 IDE so that it could be run locally on our BeagleBone.
In the second part of the chapter, we enhanced our GUI so that, in addition to controlling the programmable attenuator, it also measured and displayed the RF power.
Once again, the GUI uses the mobile JavaScript add-on, so that the attenuator and power meter can be controlled from a tablet or smartphone.
