Function Documentation

hid_device_register()

int hid_device_register	(	const struct device *	dev,
		const uint8_t *const	rdesc,
		const uint16_t	rsize,
		const struct hid_device_ops *const	ops )

#include <zephyr/usb/class/usbd_hid.h>

Register HID device report descriptor and user callbacks.

The device must register report descriptor and user callbacks before USB device support is initialized and enabled.

Parameters

[in]	dev	Pointer to HID device
[in]	rdesc	Pointer to HID report descriptor
[in]	rsize	Size of HID report descriptor
[in]	ops	Pointer to HID device callbacks

hid_device_submit_report()

int hid_device_submit_report	(	const struct device *	dev,
		const uint16_t	size,
		const uint8_t *const	report )

#include <zephyr/usb/class/usbd_hid.h>

Submit new input report.

Submit a new input report to be sent via the interrupt IN pipe. If sync is true, the functions will block until the report is sent. If the device does not provide input_report_done() callback, hid_device_submit_report() will be processed synchronously.

Parameters

[in]	dev	Pointer to HID device
[in]	size	Size of the input report
[in]	report	Input report buffer. Report buffer must be aligned.

Returns

0 on success, negative errno code on fail.
