/*
 Frequency Generator with SCPI parser

  setup: 

 1. programm your Arduino
 2. addapt the serial port in your python script to the serial port used on your PC
 3. run the python script 

 PC: python with tkinter and pyserial
 MC: any Arduino

 22.05.06 first version by mchris
 22.05.08 V0.2, SCPI parser lib included by mchris

 Use SCPI library from
 https://github.com/Vrekrer/Vrekrer_scpi_parser
