Detailed Description

Collects data from Nucleo to computer.

Implements a system to open and run python file in Spyder that acts as the UI front end. In the Spyder console, Pressing 'G' key will begin data collection and 'S' key will terminate data collection. The data collected is stored in a local array on local and transmitted as a batch to the laptop and saved within a .CSV. Plots the data in the PC using the matplotlib module. The link to the code can be found here: https://bitbucket.org/mzaman01/me305_labs/src/master/LabFF/UI_front.py

def UI_front1.getData ( )

Initiates UI_data to start collecting data to send back to UI_front.

Sends 'G' to the UI_data class to start running through the data. The data sent back is transferred into a string to be processed. Timeout is created if nothing is returned.

Returns: Nucleo data in string form

◆ key_callback()

def UI_front1.key_callback ( key )

callback function called when keyboard key has been pressed

Parameters

key	input to trigger or turn off callback

Variable Documentation

◆ fileData

UI_front1.fileData = open('UIdata.txt', "w+")

file name to save the data fileName = input("Type the .txt filename you would like to save the data on (ex: UI_data.txt): ")

Create file base to save .CSV data
