Application Folder
==================
This folder provides various applications found in sub-directories.
Application entry points with their requirements are gathered together in
in two files:
- exec_nuttapp_proto.h Entry points, prototype function
- exec_nuttapp_list.h Application specific information and requirements
Information is collected during the make .depend process.
To execute an application function:
exec_nuttapp() is defined in the include/nuttx/nuttapp.h
NuttShell provides transparent method of invoking the command, when the
following option is enabled:
CONFIG_EXAMPLES_NSH_BUILTIN_APPS=y
To select which application to be included in the build process set your
preferences in the nuttx/.config file as:
To include applications under the nuttx apps directory:
CONFIG_BUILTIN_APPS_NUTTX=y/n
where each application can be controlled as:
CONFIG_BUILTIN_APPS_<NAME>=y/n
When the user defines an option:
CONFIG_BUILTIN_APP_START=<application name>
that application shall be invoked immediately after system starts.
Note that application name must be provided in ".." as: "hello",
will call:
int hello_main(int argc, char *argv[])
Application skeleton can be found under the hello sub-directory,
which shows how an application can be added to the project. One must
define:
1. create sub-directory as: appname
2. provide entry point: appname_main()
3. set the requirements in the file: Makefile, specially the lines:
APPNAME = appname
PRIORITY = SCHED_PRIORITY_DEFAULT
STACKSIZE = 768
ASRCS = asm source file list as a.asm b.asm ...
CSRCS = C source file list as foo1.c foo2.c ..
4. add application in the apps/Makefile
