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 nuttx/include/apps/apps.h NuttShell provides transparent method of invoking the command, when the following option is enabled: CONFIG_NSH_BUILTIN_APPS=y in the NuttX configuration. A special configuration file is used to configure which applications are to be included in the build. This file is configs/<board>/<configuration>/appconfig. The existence of the appconfig file in the board configuration directory is sufficient to enable building of applications. The appconfig file is copied into the apps/ directory as .config when NuttX is configured. .config is included in the toplevel apps/Makefile. As a minimum, this configuration file must define files to add to the CONFIGURED_APPS list like: CONFIGURED_APPS += hello/.built_always poweroff/.built_always jvm/.built_always The form of each entry is <dir>/<dependency> when: <dir> is the name of a subdirectory in the apps directory, and <dependency> is a make dependency. This will be "touch"-ed each time that the sub-directory is rebuilt. 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
