Constructor & Destructor Documentation

__init__()

def UITaskW2.UITask.__init__	(		self,
			collectionDuration = 30,
			frequency = 10
	)

Constructor of UITask.

This construction takes two attributes called collectionDuration and frequency. collectionDuration is the amount of time in seconds the user wishes to collect data. The frequency is slightly different than a normal frequency. This is not related to the frequency at which the UITask runs, however, it is the frequency at which the encoderTask runs. It is important to keep these the same as is creates a related time data array for how long the and how fast the encoder is running.

Parameters

collectionDuration	Time for which the task runs.
frequency	Frequency at which the encoder is collecting data in the encoderTask. They must match.

run()

def UITaskW2.UITask.run

(

self

)

Runs the finite state machine of the UITask.

This finite state machine has approximately 3 state. The first state waits for a 'g' keystroke from the user to start data collection. The second state waits for other commands from the user like 'p', 's', 'd', and 'z'. Once done collecting data, the third state send the data collected, which is waiting in a queue in share.py, via the UART port to the front end.
