/*
* "ui.cpp"
*
* This file implements the touch screen interface for the TinySA.
*
* Modifications through Version 2.5:
*
* Lots of general cleanup; removed a lot of the menu processing that was left
* over from the NanoVNA code but not used here including the "marker" and
* "calibration" stuff. For now some NanoVNA holdovers are left intact as they
* may be used in the future such as multiple "traces".
*
*
* Modifications in Version 2.6 by WA2FZW:
*
* Replaced the use of macros to define the menu items and replaced those with
* a class/object implementation; much neater!
*
*
* Modifications in Version 2.7 by WA2FZW:
*
* Eliminated the "kpf" array which contained the characters used to paint the numbers
* in the keypad keys and in the numerical input box. The "kpf" array is replaced with
* the "KP_Font" array, which contains bitmaps for the characters that make for a much
* better looking display! I also eliminated all the characters leftover from the
* NanoVNA code that aren't used here.
