Dccharacter responded to yesterday’s post about driving two character LCDs in parallel:
Guys tested better idea on roboforum.ru: if you put all the lines but ENABLE in parallel, you can drive as many LCDs as you want by 10+N MCU pins (where N is number of displays, or 6+N – depending on mode 8 bits or 4 bits). Enable in this case just acts as chip select.
