Phidgets servos for C and Python examples

Using Phidgets servo controllers from C and Python on Linux including Raspberry Pi. NOTE: This was written for Phidgets 21, and has not been tested with the major updates in Phidgets 22.

Python Phidgets

The Python helper code comes directly from Phidgets, and attempts to do the opening and closing of drive connections without cluttering your codebase. Using it requires Phidgets to be installed.

Detect drive controller connected

This is a test to indicate your drivers are installed and connected to the controller:

cc HelloWorld.c -o HelloWorld -lphidget21

./HelloWorld

You will see when you plug or unplug the Phidgets controller(s) and get their serial number(s).

Simple C example

Allows overriding motor action, to avoid having to pull power cord if main program crashes:

cc simple.c -o simple -lphidget21

./simple steps serialnum

where:

• steps is the forward or reverse number of steps (signed integer)
• serialnum is the serial number of the controller to use (leaving blank autoselects)
