MobiFlight Community Support

Hi guys

Just a quick question, Can mobiflight work with a Arduino Mega board running FMC/CDU controls?

I have a pcv board for a FMC, it was designed to use a 9x8 matrix keyboard but I've no idea how to program an Arduino chip for my own use, so I've now got a blank pcb (no connections just holes) to use as a placeholder and instead of using 17 pins to control how it should be, I'm just going to use 2 mega cards to run the 69 keys?

Yes. Currently MobiFlight doesn’t support a key matrix.
You would have to connect all buttons individually to a pin. But two cards would do.

Perfect thanks

And mobi Can access all the FMC buttons? Can it do the Exec Led?

Is there an output for the screen display or would this be better to adjust a panel to create a dragable screen?

The screen display would be typically connected via your graphics card or onboard hdmi/display port/vga.

What is a "blank" PCB without connections ?

If you realy got a blank one then it possible..... You just need to wire the 2 Pins of each Button in a correct way.
BUT If you mean you use the original PCB ( with the printed lines for the matrix logic) and you just like to ignore the 17 Matrix Output Pins then this will not work.....
Cause your switches then be connected via the wires you solder on it and SAME TIME by the printed Lines.
Whatever you not use the 17 Pins..... The internal lines already "bridge" the collumns and lines of the Matrix.... So i think this occure in short circuits finaly.

About Display.

As Sebastian said.....
Most users set a VGA Screen there and connect it as a additional Monitor.
In PMDG you simply "undock" the FMC Display as a free window and you move it over your desktop to the other screen.
BUT
Its also possible to read the Data directly via FSUIPC..... Then you need a own Programm that use this data. Basicly this can be done with a original FMC Display or also with a VGA Screen again...... But now you not need to move the PMDG FMC Window...... Now you can create those windows by a own programm. Usefull if you plan to build this on a client Computer to reduce GPU Power on main PC and save FPS.
Just Note..... This i difficult and advanced ! Thats why 99% of users simply move the window and be happy.

with a blank PCB ;-)

Hello Sebastian,

I tried to program as Event id instructed, but when I push for example 1 the result become double 11. The event id I put 70193 with 1 for push and the same 70193 with 0 for release. Please help me to solve the problem. Thanks lot in advance...

Hi Herly.

Like all other PMDG Events we got the typical PMDG Logics.

Latching Switches work with Parameter for Positions like "0" for Left, "1" for Mid "2" for Right ...... Or 0= OFF 1= ON
Momentary Switches NOT know Status Parameters.... They work with MOUSE ACTIONS

So you did 2 mistakes.

1. You use a on release Command..... Not needed for momentary buttons
2. You use wrong Parameter..... Left Single is correct here..... 536870912

Hallo Pizman,

Finally it works, thanks lot for your help..

Regards,
Herly
