user-space program. As a result, this example cannot be used if a
|

NuttX is built as a protected, supervisor kernel (CONFIG_NUTTX_KERNEL).
|

|
||||
examples/usbterm
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
This example implements a little USB terminal.. more of a USB "chat"
|
||||
edited lines are received from the remote host connected via USB
|
||||
serial and echoed out the target serial console. Edited lines from
|
||||
the local target serial console are received and forwarded to the
|
||||
remote host via USB serial.
|
||||
|
||||
Configuration options:
|
||||
|
||||
CONFIG_EXAMPLES_UBSTERM_BUILTIN - Build the usbterm example as an NSH
|
||||
built-in command. NOTE: This is not fully functional as of this
|
||||
writing.. It should work, but there is no mechanism in place yet
|
||||
to exit the USB terminal program and return to NSH.
|
||||
CONFIG_EXAMPLES_USBTERM_BUFLEN - The size of the input and output
|
||||
buffers used for receiving data. Default 256 bytes.
|
||||
|
||||
If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB, or
|
||||
CONFIG_USBDEV_TRACE), then the example code will also manage the USB trace
|
||||
output. The amount of trace output can be controlled using:
|
||||
|
||||
CONFIG_EXAMPLES_USBTERM_TRACEINIT
|
||||
Show initialization events
|
||||
CONFIG_EXAMPLES_USBTERM_TRACECLASS
|
||||
Show class driver events
|
||||
CONFIG_EXAMPLES_USBTERM_TRACETRANSFERS
|
||||
Show data transfer events
|
||||
CONFIG_EXAMPLES_USBTERM_TRACECONTROLLER
|
||||
Show controller events
|
||||
CONFIG_EXAMPLES_USBTERM_TRACEINTERRUPTS
|
||||
Show interrupt-related events.
|
||||
|
||||
Error results are always shown in the trace output
|
||||
|
||||
Other relevant configuration options: CONFIG_CDCSER selected by the
|
||||
Prolifics emulation (not defined) and the CDC serial implementation
|
||||
(when defined). CONFIG_USBDEV_TRACE_INITIALIDSET.
