 * May 30, 2020
 * KK4DAS, Dean Souleles, KK4DAS@gmail.com
 * 
 * Demonstration Program for SSB_TFT_Display
 * This demonstrates a basic SSB control panel with the following features:
 *     Dual VFO A/B
 *     Mode indicator  SSB/LSB
 *     Tx/Rx ndicator
 *     TuningStep Inidicator
 *     S Meter
 *     Banner including Call sign
 *  
 * All of the display management is handled in the file SSB_TFT_Display, please read the documentation
 * provided at the top of SSB_TFT_Display.ino
 * 
 * 
 * NOTE TO BUILDERS
 * This is not a complete radio control sketch. It is the Display software only. In the spirit of modular design 
 * it is stand-alone and not dependent on using an SI-5351 or any other specific hardware, or on my particular 
 * hardware selection of switches, buttons and knobs.  The demonstration sketch shows how to update the display,  
 * but you need to provide the code to determine what the actual values should be. You will likely need other 
 * libraries like the Si5351 and a Rotary encoder library aside from the GFX and the ILI9341. 
 *
