This sample app demonstrates use of a USB Human Interface Device (HID) driverby the Zephyr project. This very simple driver enumerates a board with a buttoninto a “mouse” that only has a left-mouse button and can’t move.This sample can be found under samples/subsys/usb/hid-mouse in theZephyr project tree.

Requirements¶

Below, we are sharing the links to USB drivers for most of the popular Android device manufacturers like Samsung, LG, Sony, Google, HTC, Motorola, Dell, etc. These USB drivers are safe to use as they are from their respective manufacturers. All the links are valid and official. We recommend you to download the latest USB drivers. Note: This is applicable only for Windows Operating Systems (Windows 7 & above). Design Space is not supported on Windows XP & Vista operating systems. Step 1 – Download and extract driver file. Click here to download the Cricut Drivers.zip file. Locate the.zip file in your Downloads folder. Right-click on the file and choose Extract All.

This project requires an USB device driver, and there must has at least oneGPIO button in your board.

To use this sample, you will require a board that defines the user switch in itsheader file. The board.h must define the following variables:

• SW0_GPIO_NAME
• SW0_GPIO_PIN

Building and Running¶

This sample can be built for multiple boards, in this example we will build itfor the nucleo_f070rb board:

After you have built and flashed the sample app image to your board, plug theboard into a host device, for example, a PC running Linux.The board will be detected as shown by the Linux dmesg command:

You can also monitor mouse events by using the standard Linux evtest command(see the Ubuntu evtest man page for more information about this tool):

When you press the button on your board, it will act as if the leftmouse button was pressed, and this information will be displayedby evtest:

Watchdog Interface.

Watchdog Reset Behavior.

Reset behavior after timeout.

WDT_FLAG_RESET_NONE¶

No reset

WDT_FLAG_RESET_CPU_CORE¶

CPU core reset

WDT_FLAG_RESET_SOC¶

Global SoC reset

Defines

WDT_OPT_PAUSE_IN_SLEEP¶

Pause watchdog timer when CPU is in sleep state.

WDT_OPT_PAUSE_HALTED_BY_DBG¶

Pause watchdog timer when CPU is halted by the debugger.

WDT_FLAG_RESET_SHIFT¶

Watchdog reset flag bit field mask shift.

WDT_FLAG_RESET_MASK¶

Watchdog reset flag bit field mask.

Typedefs

typedef void (*wdt_callback_t)(structdevice *dev, int channel_id)¶

Watchdog callback.

typedef wdt_api_setup¶

Callback API for setting up watchdog instance. See wdt_setup() for argument descriptions.

typedef wdt_api_disable¶

Callback API for disabling watchdog instance. See wdt_disable() for argument descriptions.

typedef wdt_api_install_timeout¶

Callback API for installing new timeout. See wdt_install_timeout() for argument descriptions.

typedef wdt_api_feed¶

Callback API for feeding specified watchdog timeout. See (wdt_feed) for argument descriptions.

Functions

static int wdt_setup(structdevice *dev, u8_t options)¶

Set up watchdog instance.

This function is used for configuring global watchdog settings that affect all timeouts. It should be called after installing timeouts. After successful return, all installed timeouts are valid and must be serviced periodically by calling wdt_feed().

Parameters

• dev: Pointer to the device structure for the driver instance.
• options: Configuration options as defined by the WDT_OPT_* constants

Return Value

• 0: If successful.
• -ENOTSUP: If any of the set options is not supported.
• -EBUSY: If watchdog instance has been already setup.

static int wdt_disable(structdevice *dev)¶

Disable watchdog instance.

This function disables the watchdog instance and automatically uninstalls all timeouts. To set up a new watchdog, install timeouts and call wdt_setup() again. Not all watchdogs can be restarted after they are disabled.

Parameters

• dev: Pointer to the device structure for the driver instance.

Return Value

• 0: If successful.
• -EFAULT: If watchdog instance is not enabled.
• -EPERM: If watchdog can not be disabled directly by application code.

static int wdt_install_timeout(structdevice *dev, conststructwdt_timeout_cfg *cfg)¶

Install new timeout.

This function must be used before wdt_setup(). Changes applied here have no effects until wdt_setup() is called.

Parameters

• dev: Pointer to the device structure for the driver instance.
• cfg: Pointer to timeout configuration structure.

Return Value

• channel_id: If successful, a non-negative value indicating the index of the channel to which the timeout was assigned. This value is supposed to be used as the parameter in calls to wdt_feed().
• -EBUSY: If timeout can not be installed while watchdog has already been setup.
• -ENOMEM: If no more timeouts can be installed.
• -ENOTSUP: If any of the set flags is not supported.
• -EINVAL: If any of the window timeout value is out of possible range. This value is also returned if watchdog supports only one timeout value for all timeouts and the supplied timeout window differs from windows for alarms installed so far.

static int wdt_feed(structdevice *dev, int channel_id)¶

Feed specified watchdog timeout.

Parameters

• dev: Pointer to the device structure for the driver instance.
• channel_id: Index of the fed channel.

Return Value

• 0: If successful.
• -EINVAL: If there is no installed timeout for supplied channel.

struct wdt_window¶

#include <watchdog.h>

Watchdog timeout window.

Zephyr Usb Devices Driver Download For Windows Xp

Each installed timeout needs feeding within the specified time window, otherwise the watchdog will trigger. If the watchdog instance does not support window timeouts then min value must be equal to 0.

Note

If specified values can not be precisely set they are always rounded up.

Parameters

Zephyr Usb Devices Driver Download For Windows 10

• min: Lower limit of watchdog feed timeout in milliseconds.
• max: Upper limit of watchdog feed timeout in milliseconds.

struct wdt_timeout_cfg¶

#include <watchdog.h>

Watchdog timeout configuration struct.

Parameters

• window: Timing parameters of watchdog timeout.
• callback: Timeout callback. Passing NULL means that no callback will be run.
• next: Pointer to the next timeout configuration. This pointer is used for watchdogs with staged timeouts functionality. Value must be NULL for single stage timeout.
• flags: Bit field with following parts:
