Thanks a lot.
I got it running. I used your code which I severely trimmed for just the case of one breadboarded rotary encoder and I was able to change values in the game.
I had to download the SDK although I’m not sure if that is necessary. I couldn’t get it to work at first and then I decided to unplug and replug the usb cable after uploading the sketch. Then I hit start on the BitsandDroids application and then I was able to change in game values using the rotary encoder.
Next Step is to check If I can receive data from MSFS 2020. So far I don’t seem to need the 10 uf capacitor in the Documentation. Hope that doesn’t change with serial reading.
I’m glad that I don’t have to DFU and reflash the firmware to get the sketch running (just unplug and replug the usb cable). I had to reflash the original firmware each time for my ATS button box because the USB hid firmware does not allow uploading a sketch.
Thanks again,
Chris
