Nextion Display Layouts by ON7LDS (for MMDVMHost)
=================================================

The screenlayout has to be selected with the parameter ScreenLayout in the
MMDVM.ini file under the Nextion section. This way, the extra functions
are activated.  

  0 = auto (future use, for now it's G4KLX layout)  
  1 = G4KLX layout  
  2 = ON7LDS layout (see README-L2)  
  3 = DIY layout  
  4 = DIY layout High Speed  
  
Layout 2 is a no-nonsense layout. It is the original (G4KLX) layout with the Talker Alias added. TA color and fonts size can not be changed. At least not easily.

Layout 3 (as is 4) is a layout without any predefined layout options (color, fonts). It sends the fields *and* information about what was sent to the display, so all layout processing can and should be done in the display ittself. 

More information about the layouts can be found in  
  * README-L2 for the screenLayout 2 setting
  * README-L2 for the screenLayout 3 and 4 settings

  
When you want extra control over what has to be sent to the Nextion display,
you could consider the program 'NextionDriver' at https://github.com/on7lds/NextionDriver as a companion to MMDVMHost.
This program sends extra information about the host to the display and can do processing which would not be the task of MMDVMHost (for example: with the help of this program, it is possible to use buttons on the display).  
In verbose mode, this program shows you all communication between MMDVMHost and the display.
