config HIDKBD_RAWSCANCODES
	bool "Use Raw Scan Codes"
	default n
	---help---

	depends on !HIDKBD_RAWSCANCODES && LIB_KBDCODEC
	---help---
		Encode special key press events in the user buffer.  In this case,

		special keys include such things as up/down arrows, home and end
		keys, etc.  If this not defined, only 7-bit print-able and control

config USBHOST_HIDMOUSE
	bool "HID Mouse Class Support"
	default n
	depends on !INT_DISABLE
	select INPUT
	select MOUSE
	---help---
		Enable support for the mouse class driver.  This also depends on
		SCHED_WORKQUEUE && !DISABLE_SIGNALS

		NOTE:  This driver checks out on a Labtec and an AOpen mouse, but
		does not work correctly on a Microsoft mouse.  A little more work
		would be needed to support the Microsoft mouse.

if USBHOST_HIDMOUSE

config HIDMOUSE_TSCIF
	bool "Touchscreen Emulation"
	default n
	---help---
		Normally, the HID mouse driver uses the mouse report structure
		defined in include/nuttx/input/mouse.h.  The mouse driver can,
		however, be configured to use the touchscreen interface defined in
		include/nuttx/input/touchcreen.h.  If the touch screen interface is
		used, only support for the left button will be provided.

		NOTE:  Unlike touchscreen drivers, mouse drivers will report
		position data even when the "pen is up", i.e., when no buttons are
		pressed.  This behavior is necessary to provide the positional data
		would would be needed to drive a cursor.  Without a cursor of some
		kind, the mouse is not very useful.  So this option may not be useful.

config HIDMOUSE_DEFPRIO
	int "Polling Thread Priority"
	default 50
	---help---
		Priority of the polling thread.  Default: 50.

		If the poll() method is enabled, this defines the maximum number
		of threads that can be waiting for mouse events.  Default: 2.

config HIDMOUSE_SWAPXY
	bool "Swap X/Y"
	default n
	---help---
		Reverse the meaning of X and Y to handle different display orientations.
		NOTE:  All of the following settings apply AFTER X and Y have been swapped.

config HIDMOUSE_XMAX

	default 320
	range 0 32767
	---help---
		This is the maximum value of the X position that will be reported.

config HIDMOUSE_YMAX
	int "Maximum Y position"
	default 240
	range 0 32767

config HIDMOUSE_XSCALE
	hex "X scaling factor"
	default 0x00010000
	---help---
		Mouse positions are accumulated from X/Y displacements reported by
		the mouse device. This setting provides a scaling value for the X
		displacement.  This is a fixed precision floating point number with
		16 bits of fraction.  So a value of 0x00010000 is 1.0, 0x00018000
		is 1.5, 0x00024000 is 2.25, etc.

		NOTE that a negative value of HIDMOUSE_XSCALE such as 0xffff0000
		(-1.0) can be used to change the direction of movement.

		Default: 0x00010000 (1.0)

config HIDMOUSE_YSCALE
	hex "Y scaling factor"
	default 0x00010000
	---help---
		Mouse positions are accumulated from X/Y displacements reported by
		the mouse device. This setting provides a scaling value for the Y
		displacement.  This is a fixed precision floating point number with
		16 bits of fraction.  So a value of 0x00010000 is 1.0, 0x00018000

		NOTE that a negative value of HIDMOUSE_YSCALE such as 0xffff0000
		(-1.0) can be used to change the direction of movement.

		Default: 0x00010000 (1.0)

config HIDMOUSE_XTHRESH
	int "X threshold"
	default 12
	---help---
		New mouse positions will only be reported when the X or Y data changes by these
		thresholds. This tradeoff reduces data rate for some loss in dragging accuracy.
		Both X and Y axis thresholding can be disabled by setting this value to zero.

		Default: 12

config HIDMOUSE_THRESHY
	int "Y threshold"
	default 12
	---help---
		New touch positions will only be reported when the X or Y data changes by these
		thresholds. This tradeoff reduces data rate for some loss in dragging accuracy.
		Both X and Y axis thresholding can be disabled by setting this value to zero.

		Default: 12

		reported. Default: 320

config HIDMOUSE_WSCALE
	hex "Wheel scaling factor"
	default 0x00010000
	---help---
		Mouse wheel position are accumulated from wheel displacements
		reported by the mouse device. This setting provides a scaling
		value for the wheel displacement.  This is a fixed precision
		floating point number with 16 bits of fraction.  So a value of
		0x00010000 is 1.0, 0x00018000 is 1.5, 0x00024000 is 2.25, etc.

		NOTE that a negative value of HIDMOUSE_XSCALE such as 0xffff0000
		(-1.0) can be used to change the direction of wheel output.

		Default: 0x00010000 (1.0)

config HIDMOUSE_WTHRESH
	int "Wheel threshold"
	default 1
	---help---
		New wheel positions will only be reported when the wheel position
		changes by these thresholds. This tradeoff reduces data rate for some
		loss in wheel responsiveness.

	---help---
		Enable verbose trace output if supported by the platform.  The

		errors, warnings, and critical messages would be logged.  If
		USBHOST_TRACE_VERBOSE is defined, then general informative trace
		information would also be included.
