The grip communicates with the VPforce main board through SPI. It’s the same way TM and Virpil communicate. If you have a debolestis shift register for the buttons it should be plug and play (just wire the adapter correctly). If you don’t have a shift register internally, walmis can supply one with your kit for $10 extra and then you just need to put that board inside the grip or somewhere between the grip and the mainboard and wire the buttons to it. If you have axis on your custom grip like a thumb stick you can pair the shift register with an arduino nano to handle the SPI conversion and pass that through the shift register. I’ve got the code worked out for that but I just haven’t shared it yet since I am in the middle of building my gimbal right now so haven’t been able to test it fully.
