I can't get ExtremeJoystickTest to compile, I may not have placed
sub_desc, usb_desc.c, usb_joystick, usb_joystick.c in the correct W10 folder.

First, you have to select a Joystick entry from the Tools/USB type menu, not the Serial entry:

Second: Joystick.Xrotate and Joystick.Yrotate are not supported for "JOYSTICK_SIZE == 12" as far as I understand C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy3\usb_joystick.h.

Third: Joystick.slider only takes 1 argument, not 2 arguments.

BTW, here is your code using "CODE" tags:

Code:

Sorry for the long text, I tried to condense it to 2 sliders,only and as I am using the Trustmaster HOTAS (left/right JS), I only want to get 2 sliders working first.

I tried all the tool setup that contain joystick. failed each time.
I don't know where the "JOYSTICK_SIZE == 12" came from
on the 2 arguments, how do you differentiate the 12 sliders?

I reduced the sample code to this and it did not compile:

void setup() {
Joystick.useManualSend(true);
}

void loop() {
Joystick.slider(1, analogRead(A6));
Joystick.slider(2, analogRead(A7));
Joystick.send_now();
delay(10);
}

this did compile:

void setup() {
Joystick.useManualSend(true);
}

void loop() {
Joystick.slider(100);
Joystick.send_now();
delay(10);
}

how would you do 10 sliders?
am I using the correct LIB?
I am not deep C++ coder, so I get one of the Engineers and work to help me this the deep code issues.
Thanks for helping me.

Hi P,
Sorry, I won't be able to help you a lot since I never played with joysticks.
What I understand sofar is that the default setting is JOYSTICK = 12, set in usb_desc.h, line 699. That setting allows Joystick.slider() to take only 1 argument. And that's why your second piece of code does compile.
Probably best to study this thread for more info.

Regards,
Paul

PS: you may want to embed your code in CODE tags (using the '#' option) for better readability:
