See also include/nuttx/usb/usbhost.h if USBHOST config USBHOST_NPREALLOC int "Number of pre-allocated class instances" default 4 ---help--- Number of pre-allocated class instances config USBHOST_BULK_DISABLE bool "Disable bulk endpoint support" default n ---help--- On some architectures, selecting this setting will reduce driver size by disabling bulk endpoint support config USBHOST_INT_DISABLE bool "Disable interrupt endpoint support" default n ---help--- On some architectures, selecting this setting will reduce driver size by disabling interrupt endpoint support config USBHOST_ISOC_DISABLE bool "Disable isochronous endpoint support" default n ---help--- On some architectures, selecting this setting will reduce driver size by disabling isochronous endpoint support config USBHOST_ASYNCH bool "Asynchronous transfer support" default n depends on USBHOST_HAVE_ASYNCH ---help--- Select if the host controller driver needs to support asynchronous I/O transfer. This may be required, for example, to receive infrequent, asynchronous input from an interrupt pipe. config USBHOST_HUB bool "USB Hub Support" default n depends on USBHOST_HAVE_ASYNCH && !USBHOST_INT_DISABLE select USBHOST_ASYNCH ---help--- Select this option to build in support for USB hubs. if USBHOST_HUB config USBHOST_HUB_POLLMSEC int "USB Hub Polling Interval (MSec)" default 400 ---help--- On higher end host controllers (OHCI and EHCI), the asynchronous, interrupt IN transfers will pend until data is available from the hub. On lower end host controllers (like STM32 and EFM32), the transfer will fail immediately when the device NAKs the first attempted interrupt IN transfer (with result == EGAIN) and the hub class driver will fall back to polling the hub. For the case of the higher end controllers, this polling interval is not critical since it would really only be used in the event of failures to communicate with the hub. But for the lower end host controllers, the asynchronous transfers are ineffective and this polling interval becomes a critical parameter that must be tuned to tradeoff CPU usage with responsiveness to hub-related events (It would, I suppose, be more efficient to use synchronous transfers with these lower end host controllers). endif # USBHOST_HUB config USBHOST_COMPOSITE bool "Composite device support" default n ---help--- Build in USB host support for connected composite devices config USBHOST_COMPOSITE_STRICT bool "Strict composite membership" default n depends on USBHOST_COMPOSITE ---help--- If selected, then the composite device will not be enumerated unless every member class in the composite is supported. If not selected then, for example, you could use the CDC/ACM interface of the device with no support for the other interfaces. config USBHOST_MSC bool "Mass Storage Class Support" default n depends on !BULK_DISABLE ---help--- Enable support for the mass storage class driver. config USBHOST_MSC_NOTIFIER bool "Support USB Mass Storage notifications" default n depends on USBHOST_MSC select WQUEUE_NOTIFIER ---help--- Enable building of USB MSC notifier logic that will execute a worker function on the low priority work queue when a mass storage device is connected or disconnected. config USBHOST_CDCACM bool "CDC/ACM support" default n depends on USBHOST_HAVE_ASYNCH && !USBHOST_BULK_DISABLE && !USBHOST_INT_DISABLE select USBHOST_ASYNCH select SERIAL_REMOVABLE ---help--- Select this option to build in host support for CDC/ACM serial devices. if USBHOST_CDCACM choice prompt "CDC/ACM Protocol" default USBHOST_CDCACM_COMPLIANT if SERIAL_OFLOWCONTROL && !USBHOST_INT_DISABLE default USBHOST_CDCACM_REDUCED if !SERIAL_OFLOWCONTROL || USBHOST_INT_DISABLE config USBHOST_CDCACM_COMPLIANT bool "CDC/ACM compliant" depends on SERIAL_OFLOWCONTROL && !USBHOST_INT_DISABLE ---help--- The device needs to implement the Abstract Control Model (ACM) subclass defined in the USB Communication Device Class (CDC) specification. This protocol requires two USB interfaces, a data interface which consists of two endpoints (bulk in + bulk out) and a control interface which consists of one interrupt in endpoint. Furthermore, on EP0 the device must implement the class-specific requests defined by the CDC specification. Because this USB protocol is compliant to the CDC/ACM standard on some other operating systems (e.g. Linux, MacOS) the device can work with in-box drivers. config USBHOST_CDCACM_REDUCED bool "CDC/ACM reduced" ---help--- This mode uses the CDC data interface (bulk in + bulk out endpoint) only. No control interface (interrupt in endpoint) is required. The device needs to implement the CDC class-specific requests, so that is still possible to support baud rate settings and serial control/ status lines. This mode is useful if the number of available endpoints is limited by hardware restrictions. If the CDC/ACM compliant protocol is selected, then the reduced protocol is supported for devices that provide not interrupt IN endpoint. This option is then most useful for testing purposes or if there are insufficient resources to support the compliant protocol. The interrupt IN control interface will not be used even if it is available in this case. config USBHOST_CDCACM_BULKONLY bool "Bulk only protocol" ---help--- The device implements only the data interface (bulk in + bulk out endpoint). The device does not provide an additional control interface and does not need to implement any class-specific requests on EP0. Because bulk transfer mode provides flow control, there is no need to support serial control/status lines. The advantage of the bulk-only protocol is that the implementation efforts on the device side are reduced to a minimum. By default, both the CDC/ACM compliant protocol and the reduced protocol are supported. This option is then most useful for testing purposes. The interrupt IN control interface will not be used even if it is available; nor will EP0 class requests. endchoice # CDC/ACM Protocol config USBHOST_CDCACM_NTDELAY int "CDC/ACM notification polling interval (MSec)" default 400 depends on USBHOST_CDCACM_COMPLIANT ---help--- On higher end host controllers (OHCI and EHCI), the asynchronous, interrupt IN transfers will pend until data is available from the hub. On lower end host controllers (like STM32 and EFM32), the transfer will fail immediately when the device NAKs the first attempted interrupt IN transfer (with result == EGAIN) and the hub class driver will fall back to polling the hub. For the case of the higher end controllers, this polling interval is not critical since it would really only be used in the event of failures to communicate with the hub. But for the lower end host controllers, the asynchronous transfers are ineffective and this polling interval becomes a critical parameter that must be tuned to tradeoff CPU usage with responsiveness to hub-related events (It would, I suppose, be more efficient to use synchronous transfers with these lower end host controllers). config USBHOST_CDCACM_RXDELAY int "RX poll delay (MSec)" default 200 ---help--- When the CDC/ACM device is inactive, the host must poll it at this rate in order to discover if it has serial data to send to us. config USBHOST_CDCACM_TXDELAY int "TX poll delay (MSec)" default 200 ---help--- When the appellation is inactive, the host must poll it at this rate in order to discover if it has serial data to send to the device. config USBHOST_CDCACM_NPREALLOC int "Preallocated state" default 0 ---help--- If this setting is zero, the CDC/ACM class driver will allocate memory as needed for CDC/ACM device state. If this value is non- zero, then it provides a number of preallocated CDC/ACM state structures. This increases the static size of the code image, but eliminates all, direct, run-time allocations by the driver. config USBHOST_CDCACM_BAUD int "Initialize CDC/ACM BAUD" default 115200 config USBHOST_CDCACM_PARITY int "Initialize CDC/ACM parity" default 0 range 0 2 ---help--- Initialize CDC/ACM parity. 0=None, 1=Odd, 2=Even.

Default: 64. config HIDKBD_NPOLLWAITERS int "Max Number of Waiters for Poll Event" default 2 ---help--- If the poll() method is enabled, this defines the maximum number of threads that can be waiting for keyboard events. Default: 2. config HIDKBD_RAWSCANCODES bool "Use Raw Scan Codes" default n ---help--- If set to y no conversions will be made on the raw keyboard scan codes. This option is useful during testing. Default: ASCII conversion. config HIDKBD_ENCODED bool "Encode Special Keys" default n depends on !HIDKBD_RAWSCANCODES && LIBC_KBDCODEC ---help--- Encode special key press events in the user buffer. In this case, the user end must decode the encoded special key values using the interfaces defined in include/nuttx/input/kbd_codec.h. These 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 ASCII characters will be provided to the user. config HIDKBD_ALLSCANCODES bool "Use All Scancodes" default n ---help--- If set to y all 231 possible scancodes will be converted to something. Default: 104 key US keyboard. config HIDKBD_NODEBOUNCE bool "Disable Debounce" default n ---help--- If set to y normal debouncing is disabled. Default: Debounce enabled (No repeat keys). endif config USBHOST_HIDMOUSE bool "HID Mouse Class Support" default n depends on !INT_DISABLE select INPUT select INPUT_MOUSE ---help--- Enable support for the mouse class driver. 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. config HIDMOUSE_STACKSIZE int "Polling thread stack size" default 1024 ---help--- Stack size for polling thread.

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

Default: 240 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.

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 if INPUT_MOUSE_WHEEL config HIDMOUSE_WMAX int "Maximum wheel position" default 320 range 0 32767 ---help--- This is the maximum value of the wheel position that will be 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.
