Someone else tried this about 18 months ago. I don't know why he abandoned it. I had a WiFi-connected ESP32/TFT running a CWP program, so it's VERY useful if it works well.

Shift registers, in this context, are a means of converting parallel data into serial. They take the parallel data in and "shift" it out one bit at a time, or take 1 bit in at a time and shift it to parallel. They usually have a way of linking between devices so you can make a chain for more parallel connections than one device can provide. The PISO variety take Parallel In and give Serial Out. You can use this to expand the number of inputs an Arduino can take OR you can use it to convey a large number of inputs through only a few wires - IIRC, this is how TM grips transfer their 20+ button data to the base using a 6 pin mini DIN connector.

The DCSBIOSBridge mentioned CAN do the job, but many people experience lag when using it. There's currently no dev for it, so it should really only be used for testing if all else fails. Rapti's response is the way to go for normal running.

You can see the hidden digits at the edges of the slot in that image. They'd use all 8s - custom 7s would cost too much.

From the addresses.h file: #define AH_64D_SEAT_POSITION 0x8750, 0x0100, 8 So if you weren't giving it all 3 of those numbers, it won't work.

Did you know this was a thing? I'm also going to look into creating a 2-seat version of the switch function.

Are you using blocking diodes in the matrix?

It's possible that's a legal liability thing.

The old version still works (I use it), but there won't be new modules added. DCS UFC X is a newer pay per module version.

Start a separate thread in this forum and we'll see what we can do.

What's your hardware setup?

It could be electrical noise. Try this: The resistors shown dotted aren't necessary - DCS-BIOS turns on those in the Arduino.

One problem you'll have is that the full rotation of the A-10 HSI is 0-65535, but the common data magnetic is 0-359. It looks like the code you have is designed to work with 0-65535 input. Try changing the value shown below. If that fails, try writing a stepper routine that takes a position number, and send it from a normal DCS-BIOS code block.

Build a stand...

As mentioned in Discord, which switches are they? It sounds like you were drawing too much current and were lucky not to blow the Arduino's regulator or I/O pins. The "bad burning smell" is the stage just before the smoke escapes!
