voltage-measure

Program developed for Raspberry Pi, for the purpose of measuring voltage, converted by ADS1115, and further processing data

Installation

Necessary modules

• sudo pip3 install -r requirements.txt
• sudo python3 -m pip install matplotlib
  For installation of PIL use
• sudo apt-get install python3-pil python3-pil.imagetk
• sudo pip3 install PIL-2.0+dummy-py2.py3-none-any.whl

Usage

python3 main.py

GUI

• Program has GUI, built using Tkinter
• For images, program uses PIL library

Data processing

User enters in entry fields of program:

• Number of voltage measurements
• Delay in ms - interval between each measurement
• Limits of y axis (using for building figure by matplotlib) After that, measured data(number of measurement, raw voltage values, converted voltage) will be written to csv file and a matplotlib will build a V = f(n) dependency

Features

• User can check the box if he wants program to remember values user entered
• User can check the box if he wants to save the figure
• User can open csv file, data from file will be displayed in text box of program
• User can open saved (in png or pdf) figure. It will be opened in program window, and can be closed by pressing on image
• Exit from program using button Quit
