Mobiflight can control 7-segent displays via the MAX7219 chip. PCB modules with eight digits and a MAX7219 controller are available around $1,-. These modules can be chained with max eight in a row whereby the three connections Data, Load, CLK run from one module to the next. This makes it possible to control 64 digits with just three Arduino outputs. The video shows how to configure four modules to show CRS(3), HDG(3), IAS(5), ALT(5) and V/S(5).
