examples
^^^^^^^^
The examples directory contains several sample applications that
can be linked with nuttx. The specific example is selected in the
configs/<board-name>/defconfig file via the CONFIG_EXAMPLE setting.
For example,
CONFIG_EXAMPLE=ostest
Selects the examples/ostest example.
examples/ostest
^^^^^^^^^^^^^^^
This is the NuttX 'qualification' suite. It attempts to exercise
a broad set of OS functionality. Its coverage is not very extensive
as of this writing, but it is used to qualify each NuttX release.
The behavior of the ostest can be modified with the following
settings in the configs/<board-name>/defconfig file:
* CONFIG_OSTEST_STACKSIZE
Used to create the ostest task. Default is 8192.
examples/nsh
^^^^^^^^^^^^
This directory containst the NuttShell (NSH). This is a primitive
shell-like application. With some additional development, NSH will
someday be a great NuttX application debugger.
The behavior of NSH can be modified with the following settings in
the configs/<board-name>/defconfig file:
* CONFIG_NSH_IOBUFFERSIZE
Size of a static I/O buffer used for file access (ignored if
there is no filesystem).
* CONFIG_EXAMPLES_NSH_TELNET
By default, NSH is configured to use the serial console.
If CONFIG_EXAMPLES_NSH_TELNET is set to 'y', then a TELENET
server front-end is selected. When this option is provided,
you must log into NuttX remotely using telnet in order to
access NSH.
If CONFIG_EXAMPLES_NSH_TELNET is selected, then there some other
configuration settings that apply:
* CONFIG_EXAMPLES_NSH_IOBUFFER_SIZE
Determines the size of the I/O buffer to use for sending/
receiving TELNET commands/reponses
* CONFIG_EXAMPLES_NSH_CMD_SIZE
The size of one parsed NSH command
* CONFIG_EXAMPLES_NSH_STACKSIZE
The stack size to use when spawning new threads as new TELNET
connections are established.
* CONFIG_EXAMPLES_NSH_DHCPC
Obtain the the IP address via DHCP.
* CONFIG_EXAMPLES_NSH_IPADDR
If CONFIG_EXAMPLES_NSH_DHCPC is NOT set, then the static IP
address must be provided.
* CONFIG_EXAMPLES_NSH_DRIPADDR
Default router IP address
* CONFIG_EXAMPLES_NSH_NETMASK
Network mask
* CONFIG_EXAMPLES_NSH_NOMAC
Set if your ethernet hardware has no built-in MAC address.
If set, a bogus MAC will be assigned.
examples/mount
^^^^^^^^^^^^^^
This contains a simple test of filesystem mountpoints.
examples/null
^^^^^^^^^^^^^
This is the do nothing application. It is only used for bringing
up new NuttX architectures.
examples/uip
^^^^^^^^^^^^
This is a port of uIP example application. It includes
conditionally compiled logic to exercise the uIP webserver,
webclient, telnet, smtp, dncpc, and resolver.
examples/netttest
^^^^^^^^^^^^^^^^^
This is a simple network test for verifying client- and server-
functionality in a TCP/IP connection.
examples/udp
^^^^^^^^^^^^
This is a simple network test for verifying client- and server-
functionality over UDP.
