Any 7-segment display in the system can contain from 1 to 8 digits and can be configured to display more than one parameter at a time, when one of them is offset from another, or multiple parameters in one display position, when certain conditions (the switch position or a dataref value) cause only one of them to be displayed.
In fact, the number of displays you can use in SimVimX System can be whatever you need in your cockpit, since you can drive up to 16 displays of different types from ONE master board pin using one output multiplexer as described below. Daisy chaining of MAX7219 modules is not supported.
You can have a total of 4 output multiplexers connected to the master board, allowing you to connect up to 64 displays (you will never need that many), or connect multiple displays and LED drivers (effectively over 2000 LEDs) to the same output multiplexers.
In case you need to use only a few 7-segment displays in the cockpit or need to add another one in addition to the displays connected to the multiplexer, you can use a "direct" connection, without a multiplexer. The "CLK" input in this case should be connected to assigned controller pin, other signal inputs (L,D and T) are the same, common for all output devices (pins #27,28).
Note: for direct connection only 8 pins from #30 to 37 can be assigned (for performance reason) for these display modules in the plugin.
Here is the wiring diagram for MAX7219 and TM1637. The difference is that the TM1637 module only has a "DIO" input, which is connected to the "T" signal line. In the example diagram you can see how 2 Max7219 and 2 TM1637 are connected directly (pins #33,34 and 36,37 are assigned as control signals for each display):
SimVimX firmware is an original code developed from scratch, specifically for MAX7219 and TM1637, in accordance with their technical specifications. No display libraries are used to improve performance.
