Examples

Selecting Examples

The examples directory contains several sample applications that can be linked with NuttX. The specific example is selected in the boards/<arch-name>/<chip-name>/<board-name>/configs/<config>/defconfig file via the CONFIG_EXAMPLES_xyz setting where xyz is the name of the example. For example:

CONFIG_EXAMPLES_HELLO=y

Selects the examples/hello "Hello, World!" example.

Built-In Functions

Some of the examples may be built as built-in functions that can be executed at run time (rather than as NuttX main programs). These built-in examples can be also be executed from the NuttShell (NSH) command line. In order to configure these built-in NSH functions, you have to set up the following:

• CONFIG_NSH_BUILTIN_APPS – Enable support for external registered, named applications that can be executed from the NSH command line (see apps/README.md for more information).
