     All library files should be placed in directories likes \sketchbook\libraries\library1\ , \sketchbook\libraries\library2\ , etc.
     Anything rotator_*.* should be in the ino directory!

+     *  
+     *  VK4GHZ Nextion firmware Version 2021-10-23 or later required.  
+     *  
+     *  This works on the understanding that the Nextion will be ready before the Arduino sends the gSC variable to it.
+     *  Therefore 2-way handshaking is not needed.
+     *  Resetting the Nextion is not needed.
+     *  
+     *  If the Nextion fails to receive gSC, then that indicates a user configuration error, or mis-wired TXD/RXD lines.
+     *  
+     *  Nextion 3.2" Enhanced is ready ~ 225 mS after powering up
+     *  Nextion 3.5" Enhanced is ready ~ 390 mS after powering up
+     *  Nextion 5.0" Enhanced is ready ~ 345 mS after powering up
+     *  Nextion 7.0" Enhanced is ready ~     mS after powering up (VK4GHZ does not have a 7.0" to test with, but will happily accept donations!)
+     *  
+     *  Tests indicate nexSerial is set 363 ~ 2400 mS after Teensy 3.2 board powers up.
+     *  This may not be the same on successive power ups. 
+     *  Dunno why?
+     *  
+     *  Sending of gSC can be delayed by increasing the value of NEXTION_GSC_STARTUP_DELAY in rotator_settings.h (default 0 mS)
+     *  However, a value of 0 works with 3.5" enhanced, being the slowest HMI to become ready.
