Raspberry Pi interfacing with SQDToolz

Certain devices in the lab are interfaced with the Raspberry Pi. For example:

• Several microwave sources converted from the USB-Serial interface into Ethernet
• Using GPIO pins to slowly toggle states on a electro-mechanical switch

There is an implementation using SSH and the paramiko module. However, this has issues when running in an IPython notebook. Therefore, the recommended approach is to run a SCPI-compatible server via a TCP-socket through which clients communicate via SCPI commands. The following documentation is relevant:

• Initial setup on the Raspberry Pi
• Setting up the Raspberry Pi SCPI server
• Developer's Notes
