I may be too stupid with the electronics because I was struggling with the shift registers and matrixes, so I finally got the MCP 23017 as one of the options you recommended. Works fine now. I am usion one Arduino pro micro, 4 x MCP23017, and your sketch. (There is a slight error in the code with the buttons; 99 as a designation is not working with maximum of 86 buttons.) I am a "FUNCTION BEFORE STYLE" guy. So while printing, I ran out of filament multiple times. using two old IPADs with spacedesk, a custom Helios profile, an old 7-inch USB monitor, and one Thrustmaster MFD. It works with my setup, and I am happy; even switching between pilot and CPG works with the displays. TEDAC display is always on Cheers LGB Hey. I'm glad you liked it. Regarding the code, it's actually the last video on my YouTube series that I've been procrastinating to record for months now. If you build it using the sketch (you can build it with shift registers instead of port expanders, and in that case you can use MMjoy2 instead of an arduino sketch), you'll have to make some adjustments to it. The 99 is because when I wrote it, I wasn't using all the pins of the expanders, therefore I used 99 for the unused ones.

The 99 is because when I wrote it, I wasn't using all the pins of the expanders, therefore I used 99 for the unused ones. Because of my lack of knowledge of electronics, I really struggled with the shift registers, and therefore I just kept your Arduino sketch with the expanders. It is working perfectly once I change the 99 to 85. All good now. Just Plain Code, no mmjoy2 necessary. In Windows it is showing up as AH-64 TEDAC, so also no confusion. The next project is your Collective. I printed out the lower part only and modified the way the collective axis is working, added a tiny display, and wrote my own code. I used these potentiometers at the other end of the lever. Held in position with hot glue. Works very well.null null
