A10 VHF COMM Display Sketches Request

[Kenpilot]

Building my A10 VHF Comm panels and I noticed for the frequency display and output for the Preselect Display, DCS Bios has you write your own code for the displays, and I'm clueless when it comes to this. Does anyone have a sketch I can "borrow" for these displays. For the Frequency display, I'm using an 8 digit 7 segmented LED display, (only 6 digits are visible in my panel) and 2 single digit 7 segmented displays for the preselect display. Thanks!!

If your chip is a Max7219 or so, you could use the ledcontrol library for your displays.

Thanks Vinc. The 4 digit 7 segment displays I have do have the max7219s attached I believe, so thank you for the suggeston for using this library. Unfortunately I still have no idea how the code should be written in the sketch as I know nothing about writing code. Up until now, I have just copied and pasted the appropriate code from BORT in to my arduino sketches. I was hoping someone that knows how to write code and has already written the code for these displays, wouldn't mind sharing it for those of us without coding knowledge and experience. If there's any kind of tutorial on writing code for these displays with regard to using them in DCS, please let me know, as I'd love to learn as well. Thanks!

@Kenpilot

not yet perfect but something you can play with and try your displays ...

One Max7219; displays 0 to 5 for the frequency and 6 and 7 for the presets

There's a "control reference" section of the DCS-BIOS files.

Thanks Vinc! I'll be trying this tonight or tomorrow. I'll PM you with any issues or further questions. Thanks so much for your help!!
