examples/composite
^^^^^^^^^^^^^^^^^^
This example test a USB composite device. The only supported composite is
CDC/ACM serial with a USB mass storage device.
Required overall configuration:
CONFIG_USBDEV - USB device support
CONFIG_USBDEV_COMPOSITE - USB composite device support
CONFIG_CDCACM - USB CDC/ACM serial device support
CONFIG_CDCACM_COMPOSITE - USB CDC/ACM serial composite device support
CONFIG_USBMSC - USB mass storage device support
CONFIG_USBMSC_COMPOSITE - USB mass storage composite device support
CONFIG_NSH_BUILTIN_APPS
This example can be built as two NSH "built-in" commands if this option
is selected: 'msconn' will connect the USB mass storage device; 'msdis'
will disconnect the USB storage device.
Configuration options unique to this example:
CONFIG_EXAMPLES_COMPOSITE_DEBUGMM
Enables some debug tests to check for memory usage and memory leaks.
CONFIG_EXAMPLES_COMPOSITE_NLUNS
Defines the number of logical units (LUNs) exported by the USB storage
driver. Each LUN corresponds to one exported block driver (or partition
of a block driver). May be 1, 2, or 3. Default is 1.
CONFIG_EXAMPLES_COMPOSITE_DEVMINOR1
The minor device number of the block driver for the first LUN. For
example, N in /dev/mmcsdN. Used for registering the block driver. Default
is zero.
CONFIG_EXAMPLES_COMPOSITE_DEVPATH1
The full path to the registered block driver. Default is "/dev/mmcsd0"
CONFIG_EXAMPLES_COMPOSITE_DEVMINOR2 and CONFIG_EXAMPLES_COMPOSITE_DEVPATH2
Similar parameters that would have to be provided if CONFIG_EXAMPLES_COMPOSITE_NLUNS
is 2 or 3. No defaults.
CONFIG_EXAMPLES_COMPOSITE_DEVMINOR3 and CONFIG_EXAMPLES_COMPOSITE_DEVPATH2
Similar parameters that would have to be provided if CONFIG_EXAMPLES_COMPOSITE_NLUNS
is 3. No defaults.
CONFIG_EXAMPLES_COMPOSITE_BUFLEN. Default 256.
CONFIG_EXAMPLES_COMPOSITE_TTYUSB - The minor number of the USB serial device.
Default is zero (corresponding to /dev/ttyUSB0. Default is zero.
CCONFIG_EXAMPLES_COMPOSITE_SERDEV - The string corresponding to
CONFIG_EXAMPLES_COMPOSITE_TTYUSB. The default is "/dev/ttyUSB0".
CONFIG_EXAMPLES_COMPOSITE_BUFSIZE - The size of the serial I/O buffer in
bytes. Default 256 byters.
If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
the example code will also manage the USB trace output. The amount of trace output
can be controlled using:
CONFIG_EXAMPLES_COMPOSITE_TRACEINIT
Show initialization events
CONFIG_EXAMPLES_COMPOSITE_TRACECLASS
Show class driver events
CONFIG_EXAMPLES_COMPOSITE_TRACETRANSFERS
Show data transfer events
CONFIG_EXAMPLES_COMPOSITE_TRACECONTROLLER
Show controller events
CONFIG_EXAMPLES_COMPOSITE_TRACEINTERRUPTS
Show interrupt-related events.
