The SimVimX firmware for a separate slave board is included to the system as addition to old method (connecting displays to master board). You need one Uno/Nano Arduino board with special SimVimLCD firmware onboard, that you should upload from the SimVimX plugin menu.
Separate, "slave" Uno or Nano board with "SimVimLCD" firmware for connecting up to 11 different size (L x H) character LCDs.
The board can be placed near to your LCD "stack" and linked with master board with 2-wire Serial interface (Rx/Tx #3 on the mastr board is used for communication). This allows to leave the master board bus for multiplexers addressing only, get more stable data flow for LCD, more control and configuration. Some pins on this LCD board are used as "power bus" to control LCDs backlight on/off on power loss or brightness
The wiring is quite simple - all signal wires (4+1) in this system are used in parallel for all connected displays, only one signal line for each display is used separatelly for every specific display.
