USB HID Joystick together with CompositeSerial

[Joshy-2010]

Hello, I am trying to use the USBComposite Library built into this STM32 core.

I have succesfully programmed myself a HID joystick ontop of the "simplejoystick" example sketch:

USBHID HID;
HIDJoystick Joystick(HID);

void setup() {
   HID.begin(HID_JOYSTICK);
   while (!USBComposite);
}
......

And I also got "CompositeSerial" to work, both seperately. The next step is to combine both into a single programm: A joystick to which I can write serial commands to activate some LEDs and other small gimics. I saw the "keyboardwithleds" example sketch (which also worked perfectly) and thought I could just replace "HID_KEYBOARD" with "HID_JOYSTICK":

USBHID HID;
HIDJoystick Joystick(HID);
USBCompositeSerial USB_Serial;

void setup() {
  HID.begin(CompositeSerial, HID_JOYSTICK);
   while (!USBComposite);
 }
......

Unfortunately, my Pc says that it could not recognize the usb device anymore. Is joystick + serial not supported? Is there another way to send joystick data both from the STM32 to the Pc while also sending small commands back to the STM32? Do I have to call a few other commands to start everything up? I saw a few other functions like "plugin2.registerComponent();" but I dont really understand that they are doing differently.

Thanks in advance

I think I have figured it out. These are the predeclared variables:

const uint8_t reportDescription[] = { HID_JOYSTICK_REPORT_DESCRIPTOR(), }; USBCompositeSerial USB_Serial; USBHID HID; HIDJoystick Joystick(HID);

And this needs to go into "void setup": HID.begin(USB_Serial, reportDescription, sizeof(reportDescription)); while (!USBComposite);

Strangly, it still reports as a keyboard, mouse and game controller in windows, even though I have only specified game controller in the "reportDescription".

Thanks. Closing as resolved
