USBHIDGamepad::USBHIDGamepad

Description
Constructs a USBHIDGamepad object.

Syntax
USBHIDGamepad(void);

Parameters
NA

Returns
NA

Example Code
Example: USBHIDGamepad
(https://github.com/ambiot/ambd_arduino/blob/dev/Arduino_package/hardware/libraries/USB/examples/USBHIDGamepad/USBHIDGamepad.ino)

Notes and Warnings
By default, the USBHIDGamepad class assumes the HID report descriptor implements a gamepad device with 16 buttons, 6 axes with 16-bit resolution and an 8-direction hat switch. This class will not work if a different gamepad report descriptor is implemented. “USBHIDGamepad.h” must be included to use the class function.

USBHIDGamepad::setReportID

Description
Set HID report ID for the HID Gamepad.

Syntax
void setReportID(uint8_t reportID);

Parameters
reportID: The report ID for the gamepad device, corresponding to the HID report descriptor.

Returns
NA

Example Code
NA

Notes and Warnings
HID report ID should start at 1. Some systems may consider a report ID of 0 as invalid. “USBHIDGamepad.h” must be included to use the class function.
