To analyze log files collected from either internal flash or with telemetry using android or GCS you can use a set of scripts written in python. You can find these files in the git repository under the python directory. They require the repository to be checked out in order to support analyzing log files from various versions.

From the Tau Labs directory, you can launch analysis using the command

./python/shell.py path/to/log/file.tll

This will bring you to an IPython environment where you can inspect data objects and plot graphs. For example to plot the Z gyro you would type:

gyro = uavo_list.as_numpy_array(UAVO_Gyros)
plot(gyro['time'], gyro['Z'])
