This guide will show you how to use SimVimPlugin to show Xplane’s radio frequencies on 7-segment display to be used on homecockpit. For more information about plugin visit: www.simvim.com
Components needed:
- Arduino Mega
- 7-segment led display with Max7219 chip
- Wall wart to power led display
Software:
- Xplane 11.30 (Cessna 172 used)
- SIMVIM 0.9.33
- This guide was done with Ubuntu but it should work also in Windows
Wiring:
- Wall wart +5V to led display VCC
- Wall wart GND to led display GND and arduino GND
- Led display:
- DN to pin 28 on Arduino Mega
- CS to pin 27 on Arduino Mega
- CLK to assigned pin (pin 36 on this guide)
- USB connection between Arduino and PC
How to:
- Go to SIMVIM configurator page: http://simvim.com/config.html and first choose following selections:
- Parameter Table
- Number of engines 1
- COM/NAV
- Com/Nav Displays

- From Com/Nav Displays:
- Click Com1_Stby_6 and…
- …from opening windows select 7-segment display

- After 7-segment display selection, select proper pin (36 on this guide) from table on right side of www-page. Check that MAX7219 is selected and click Done

- Go to top off configurator page and click red save button. It downloads a data.cfg file for you.

- Copy data.cfg file from your downloads folder and replace old data.cfg file on Xplane’s SimVimCockpit plugin folder (…\X-Plane 11\Resources\plugins\SimVim).
- Switch to Xplane, and with a plane running, go to plugins and SimVimPlugin’s status window. Click reload if needed.
- Now try to change planes NAV1 radios standby frequency. Changes should be seen in 7-segment led display.
