when I make my steering wheel on the original library, the code works for me and when I calibrate the device everything is correct, but when I do it on this library, the code is also compiled but does not react to HID-device at the same time, if I make a welcome through the "println" com port, you can see that the signals there are also they are working if you do it without ffb on the library with ffb the story is the same when using the original library everything works correctly I don’t know if it’s my problem or it’s the library just like I already mentioned I’m a beginner
code with ffb on this library but of course it doesn’t work, I don’t know why the device also doesn’t react on the PC
17.02 I made a working code with ffb on a multi-turn potentiometer, initially there was an idea to do it on an encoder, but I have a bad usual one for 20 cycles, which, as I understand it, is not very suitable for this task because it does not read data very correctly. The only thing to do is to put the right values in myeffectparams. Now my question is what are the effects with what values you need to set and what specific gains that would be the maximum effects from the steering wheel with a minimum loss of fps. I used the Gyver Weel project as a code source: https://alexgyver.ru/gyverwheel/ . In the code, you can have a debug mode to see if the knobs and buttons work for you, as well as the calibration mode that you need to do it:
1.Set the potentiometers to the minimum position you need 2.Hold down the calibration button 3.Connect usb cable to arduino 4.Wait 5 seconds 5.Release the calibration button 6.Set the potentiometer to the maximum position you need 7.Click on the calibration button

Hello everyone, I'm new to arduino and I'm trying to write my own steering wheel with FFB, so far it's not very good. I can write code without FFB but I want to have it I have everything I need to create it motor and h-bridges the code I try to write gives me a lot of errors that I don't know how to fix. I would be very grateful if there is somewhere a code with ffb on this library, because while I understand a little. Also my experience in programming is low, all I did was read the book "a byte of python" I also know layout, but this has nothing to do with my question
