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
