pololu_test

This is a simple utility meant to test the integrity of an I2C bus created using a Pololu "Pololu Isolated USB-to-I²C Adapter with Isolated Power" interface (Pololu item #: 5397)

It probably works with the confusingly similar product: "Pololu Isolated USB-to-I²C" Adapter (Pololu item #: 5396). I don't know.

This utility reads the device information and reports the interface onformation and then enumerates the addresses of devices found on the bus: The utility currently devfaults to using the port "/dev/ttyACM2" which appears in my /dev folder when the device is plugged in. YMMV.

No facility short of rebuilding the utility with an alternative path string for the port is currently available.

To build, do the usual CMake thing:

Clone this repo to ./pololu_test
$ cd pololu_test
$ mkdir build
$ cd build
$ cmake ..
$ make

To run, cd to:

• pololu_test/cmake-build-debug/
• (or pololu_test/cmake-build-release/)

then:

$ ./pololu_test

Connecting to /dev/ttyACM2...
Connected.
