The build structure of the Espressif IoT Development Framework explained.
An ESP-IDF project can be seen as an almagation of a number of components.
For example, for a webserver that shows the current humidity, we would
have:
- The ESP32 base libraries (libc, rom bindings etc)
- The WiFi drivers
- A TCP/IP stack
- The FreeRTOS operating system
- A webserver
- A driver for an humidity sensor
- Main code tying it all together
ESP-IDF makes these components explicit and configurable. To do that, when a project
is compiled, the build environment will look up all the components in the
ESP-IDF directories, the project directories and optionally custom other component
directories. It then allows the user to configure compile-time options using
a friendly text-based menu system to customize the ESP-IDF as well as other components
to the requirements of the project. After the components are customized, the
build process will compile everything into an output file, which can then be uploaded
into a board in a way that can also be defined by components.
A project in this sense is defined as a directory under which all the files required
to build it live, excluding the ESP-IDF files and the toolchain. A simple project
tree looks like this:
- myProject/ - build/
- components/ - component1/ - Makefile
- Kconfig
- src1.c
- component2/ - Makefile
- Kconfig
- src1.c
- main/ - src1.c
- src2.c
- Makefile
As we can see, a project consists of a components/ subdirectory containing its
components as well as one or more directories containing the project-specific
sources; by default a single directory called 'main' is assumed. The project
directory will also have a Makefile where the projects name as well as optionally
other options are defined. After compilation, the project directory will contain
a 'build'-directory containing all of the objects, libraries and other generated
files as well as the final binary.
Components also have a Makefile containing various definititions influencing
the build process of the component as well as the project it's used in, as
well as a Kconfig file defining the compile-time options that are settable
by means of the menu system.
Project makefile variables that can be set by the programmer:
PROJECT_NAME: Mandatory. Name for the project
BUILD_DIR_BASE: Set the directory where all objects/libraries/binaries end up in.
Defaults to $(PROJECT_PATH)/build
COMPONENT_DIRS: Search path for components. Defaults to the component/ directories
in the ESP-IDF path and the project path.
COMPONENTS: A list of component names. Defaults to all the component found in the
COMPONENT_DIRS directory
EXTRA_COMPONENT_DIRS: Defaults to unset. Use this to add directories to the default
COMPONENT_DIRS.
SRCDIRS: Directories under the project dir containing project-specific sources.
Defaults to 'main'. These are treated as 'lite' components: they do not have
include directories that are passed to the compilation pass of all components and
they do not have a Kconfig option.
Component makefile variables that can be set by the programmer:
COMPONENT_ADD_INCLUDEDIRS: Relative path to include directories to be added to
the entire project
COMPONENT_PRIV_INCLUDEDIRS: Relative path to include directories that are only used
when compiling this specific component
COMPONENT_DEPENDS: Names of any components that need to be compiled before this component.
COMPONENT_ADD_LDFLAGS: Ld flags to add for this project. Defaults to -l$(COMPONENT_NAME).
Add libraries etc in the current directory as $(abspath libwhatever.a)
COMPONENT_EXTRA_INCLUDES: Any extra include paths. These will be prefixed with '-I' and
passed to the compiler; please put absolute paths here.
COMPONENT_SRCDIRS: Relative directories to look in for sources. Defaults to '.', the current
directory (the root of the component) only. Use this to specify any subdirectories. Note
that specifying this overwrites the default action of compiling everything in the
components root dir; to keep this behaviour please also add '.' as a directory in this
list.
COMPONENT_OBJS: Object files to compile. Defaults to the .o variants of all .c and .S files
that are found in COMPONENT_SRCDIRS.
COMPONENT_EXTRA_CLEAN: Files that are generated using rules in the components Makefile
that also need to be cleaned
COMPONENT_BUILDRECIPE: Recipe to build the component. Optional. Defaults to building all
COMPONENT_OBJS and linking them into lib(componentname).a
COMPONENT_CLEANRECIPE: Recipe to clean the component. Optional. Defaults to removing
all built objects and libraries.
COMPONENT_BUILD_DIR: Equals the cwd of the component build, which is the build dir
of the component (where all the .o etc files should be created).
These variables are already set early on in the Makefile and the values in it will
be usable in component or project Makefiles:
CC, LD, AR, OBJCOPY: Xtensa gcc tools
HOSTCC, HOSTLD etc: Host gcc tools
LDFLAGS, CFLAGS: Set to usable values as defined in ESP-IDF Makefile
PROJECT_NAME: Name of the project, as set in project makefile
PROJECT_PATH: Path to the root of the project folder
COMPONENTS: Name of the components to be included
CONFIG_*: Values set by 'make menuconfig' also have corresponding Makefile variables.
For components, there also are these defines:
COMPONENT_PATH: Absolute path to the root of the source tree of the component we're
compiling
COMPONENT_LIBRARY: The full path to the static library the components compilation pass
is supposed to generate
How this works:
The Make process is always invoked from the project directory by the
user; invoking it anywhere else gives an error. This is what happens if
we build a binary:
The Makefile first determines how it was included. It determines it was
included as a project file in this case and will continue to figure out
various paths as well as the components available to it. It will also
collect the ldflags and includes that the components specify they need.
It does this by running a dummy Make on the components with a target that
will output these values.
The Makefile will then create targets to build the lib*.a libraries of
all components and make the elf target depend on this. The targets
invoke Make on the makefiles of the components in a subshell: this way
the components have full freedom to do whatever is necessary to build
the library without influencing other components. By default, the
component includes the utility makefile $(IDF_PATH)/make/component.mk.
This provides default targets and configurations that will work
out-of-the-box for most projects.
For components that have parts that need to be run when building of the
project is done, you can create a file called Makefile.projbuild in the
component root directory. This file will be included in the main
Makefile. For the menu, there's an equivalent: if you want to include
options not in the 'components' submenu, create a Kconfig.projbuild and
it will be included in the main menu of menuconfig. Take good care when
(re)defining stuff here: because it's included with all the other
.projbuild files, it's possible to overwrite variables or re-declare
targets defined in the ESP-IDF makefile/Kconfig and other .projbuild files
WRITING COMPONENT MAKEFILES
A component consists of a directory which doubles as the name for the
component: a component named 'httpd' lives in a directory called 'httpd'
Because components usually live under the project directory (although
they can also reside in an other folder), the path to this may be
something like /home/myuser/projects/myprojects/components/httpd .
One of the things that most components will have is a Makefile,
containing instructions on how to build the component. Because the
build environment tries to set reasonable defaults that will work most
of the time, a component Makefile can be pretty small. At the absolute
minimum, it will just include the ESP-IDF component makefile, which adds
component functionality:
----8<----
include $(IDF_PATH)/make/component.mk
---->8----
This will take all the .c and .S files in the component root and compile
them into object files, finally linking them into a library.
Subdirectories are ignored; if your project has sources in subdirectories
instead of in the root of the component, you can tell that to the build
system by setting COMPONENT_SRCDIRS:
----8<----
COMPONENT_SRCDIRS := src1 src2
include $(IDF_PATH)/make/component.mk
---->8----
This will compile all source files in the src1/ and src2/ subdirectories
instead.
The standard component.mk logic adds all .S and .c files in the source
directories as sources to be compiled unconditionally. It is possible
to circumvent that logic and hardcode the objects to be compiled by
manually setting the COMPONENT_OBJS variable to the name of the
objects that need to be generated:
----8<----
COMPONENT_OBJS := file1.o file2.o thing/filea.o thing/fileb.o anotherthing/main.o
include $(IDF_PATH)/make/component.mk
---->8----
This can also be used in order to conditionally compile some files
dependent on the options selected in the Makefile:
Kconfig:
----8<----
config FOO_ENABLE_BAR
bool "Enable the BAR feature."
help
This enables the BAR feature of the FOO component.
---->8----
Makefile:
----8<----
COMPONENT_OBJS := foo_a.o foo_b.o $(if $(CONFIG_FOO_ENABLE_BAR),foo_bar.o foo_bar_interface.o)
include $(IDF_PATH)/make/component.mk
---->8----
Some components will have a situation where a source file isn't supplied
with the component itself but has to be generated from another file. Say
our component has a header file that consists of the converted binary
data of a BMP file, converted using a hypothetical tool called bmp2h. The
header file is then included in as C source file called graphics_lib.c.
----8<----
COMPONENT_EXTRA_CLEAN := logo.h
graphics_lib.o: logo.h
logo.h: $(COMPONENT_PATH)/logo.bmp
bmp2h -i $^ -o $@
include $(IDF_PATH)/make/component.mk
---->8----
In this example, graphics_lib.o and logo.h will be generated in the
current directory (the build directory) while logo.bmp comes with the
component and resides under the component path. Because logo.h is a
generated file, it needs to be cleaned when make clean is called which
why it is added to the COMPONENT_EXTRA_CLEAN variable.
This will work just fine, but there's one last cosmetic improvement that
can be done. The make system tries to make the make process somewhat
easier on the eyes by hiding the commands (unless you run make with the
V=1 switch) and this does not do that yet. Here's an improved version
that will output in the same style as the rest of the make process:
----8<----
COMPONENT_EXTRA_CLEAN := test_tjpgd_logo.h
graphics_lib.o: logo.h
logo.h: $(COMPONENT_PATH)/logo.bmp
$(vecho) BMP2H $@
$(Q) bmp2h -i $^ -o $@
include $(IDF_PATH)/make/component.mk
---->8----
Obviously, there are cases where all these recipes are insufficient for a
certain component, for example when the component is basically a wrapper
around another third-party component not originally intended to be
compiled under this build system. In that case, it's possible to forego
the build system entirely by setting COMPONENT_OWNBUILDTARGET and
possibly COMPONENT_OWNCLEANTARGET and defining your own build- and clean
target. The build target can do anything as long as it creates
$(COMPONENT_LIBRARY) for the main file to link into the project binary,
and even that is not necessary: if the COMPONENT_ADD_LDFLAGS variable
is set, the component can instruct the linker to do anything else as well.

Expat, Release 2.2.0
This is Expat, a C library for parsing XML, written by James Clark.
Expat is a stream-oriented XML parser. This means that you register
handlers with the parser before starting the parse. These handlers
are called when the parser discovers the associated structures in the
document being parsed. A start tag is an example of the kind of
structures for which you may register handlers.
Windows users should use the expat_win32bin package, which includes
both precompiled libraries and executables, and source code for
developers.
Expat is free software. You may copy, distribute, and modify it under
the terms of the License contained in the file COPYING distributed
with this package. This license is the same as the MIT/X Consortium
license.
Versions of Expat that have an odd minor version (the middle number in
the release above), are development releases and should be considered
as beta software. Releases with even minor version numbers are
intended to be production grade software.
If you are building Expat from a check-out from the CVS repository,
you need to run a script that generates the configure script using the
GNU autoconf and libtool tools. To do this, you need to have
autoconf 2.58 or newer. Run the script like this:
./buildconf.sh
Once this has been done, follow the same instructions as for building
from a source distribution.
To build Expat from a source distribution, you first run the
configuration shell script in the top level distribution directory:
./configure
There are many options which you may provide to configure (which you
can discover by running configure with the --help option). But the
one of most interest is the one that sets the installation directory.
By default, the configure script will set things up to install
libexpat into /usr/local/lib, expat.h into /usr/local/include, and
xmlwf into /usr/local/bin. If, for example, you'd prefer to install
into /home/me/mystuff/lib, /home/me/mystuff/include, and
/home/me/mystuff/bin, you can tell configure about that with:
./configure --prefix=/home/me/mystuff
Another interesting option is to enable 64-bit integer support for
line and column numbers and the over-all byte index:
./configure CPPFLAGS=-DXML_LARGE_SIZE
However, such a modification would be a breaking change to the ABI
and is therefore not recommended for general use - e.g. as part of
a Linux distribution - but rather for builds with special requirements.
After running the configure script, the "make" command will build
things and "make install" will install things into their proper
location. Have a look at the "Makefile" to learn about additional
"make" options. Note that you need to have write permission into
the directories into which things will be installed.
If you are interested in building Expat to provide document
information in UTF-16 encoding rather than the default UTF-8, follow
these instructions (after having run "make distclean"):
1. For UTF-16 output as unsigned short (and version/error
strings as char), run:
./configure CPPFLAGS=-DXML_UNICODE
For UTF-16 output as wchar_t (incl. version/error strings),
run:
./configure CFLAGS="-g -O2 -fshort-wchar" \
CPPFLAGS=-DXML_UNICODE_WCHAR_T
2. Edit the MakeFile, changing:
LIBRARY = libexpat.la
to:
LIBRARY = libexpatw.la
(Note the additional "w" in the library name.)
3. Run "make buildlib" (which builds the library only).
Or, to save step 2, run "make buildlib LIBRARY=libexpatw.la".
4. Run "make installlib" (which installs the library only).
Or, if step 2 was omitted, run "make installlib LIBRARY=libexpatw.la".
Using DESTDIR or INSTALL_ROOT is enabled, with INSTALL_ROOT being the default
value for DESTDIR, and the rest of the make file using only DESTDIR.
It works as follows:
$ make install DESTDIR=/path/to/image
overrides the in-makefile set DESTDIR, while both
$ INSTALL_ROOT=/path/to/image make install
$ make install INSTALL_ROOT=/path/to/image
use DESTDIR=$(INSTALL_ROOT), even if DESTDIR eventually is defined in the
environment, because variable-setting priority is
1) commandline
2) in-makefile
3) environment
Note: This only applies to the Expat library itself, building UTF-16 versions
of xmlwf and the tests is currently not supported.
Note for Solaris users: The "ar" command is usually located in
"/usr/ccs/bin", which is not in the default PATH. You will need to
add this to your path for the "make" command, and probably also switch
to GNU make (the "make" found in /usr/ccs/bin does not seem to work
properly -- apparently it does not understand .PHONY directives). If
you're using ksh or bash, use this command to build:
PATH=/usr/ccs/bin:$PATH make
When using Expat with a project using autoconf for configuration, you
can use the probing macro in conftools/expat.m4 to determine how to
include Expat. See the comments at the top of that file for more
information.
A reference manual is available in the file doc/reference.html in this
distribution.
The homepage for this project is http://www.libexpat.org/. There
are links there to connect you to the bug reports page. If you need
to report a bug when you don't have access to a browser, you may also
send a bug report by email to expat-bugs@mail.libexpat.org.
Discussion related to the direction of future expat development takes
place on expat-discuss@mail.libexpat.org. Archives of this list and
other Expat-related lists may be found at:

"library boundary." This will default to cdecl, and
try really hard to tell the compiler that's what we
want.
XMLIMPORT - Whatever magic is needed to note that a function is
to be imported from a dynamically loaded library
(.dll, .so, or .sl, depending on your platform).
The XMLCALL macro was added in Expat 1.95.7. The only one which is
expected to be directly useful in client code is XMLCALL.
Note that on at least some Unix versions, the Expat library must be
compiled with the cdecl calling convention as the default since

Internal definitions used by Expat. This is not needed to compile

The following calling convention macros are defined for frequently
called functions:
FASTCALL - Used for those internal functions that have a simple
body and a low number of arguments and local variables.
PTRCALL - Used for functions called though function pointers.
PTRFASTCALL - Like PTRCALL, but for low number of arguments.
inline - Used for selected internal functions for which inlining
may improve performance on some platforms.
Note: Use of these macros is based on judgement, not hard rules,

Welcome to cJSON.
cJSON aims to be the dumbest possible parser that you can get your job done with.
It's a single file of C, and a single header file.
JSON is described best here: http://www.json.org/
It's like XML, but fat-free. You use it to move data around, store things, or just
generally represent your program's state.
First up, how do I build?
Add cJSON.c to your project, and put cJSON.h somewhere in the header search path.
For example, to build the test app:
gcc cJSON.c test.c -o test -lm
./test
As a library, cJSON exists to take away as much legwork as it can, but not get in your way.
As a point of pragmatism (i.e. ignoring the truth), I'm going to say that you can use it
in one of two modes: Auto and Manual. Let's have a quick run-through.
I lifted some JSON from this page: http://www.json.org/fatfree.html
That page inspired me to write cJSON, which is a parser that tries to share the same
philosophy as JSON itself. Simple, dumb, out of the way.
Some JSON:
{
"name": "Jack (\"Bee\") Nimble",
"format": {
"type": "rect",
"width": 1920,
"height": 1080,
"interlace": false,
"frame rate": 24
}
}
Assume that you got this from a file, a webserver, or magic JSON elves, whatever,
you have a char * to it. Everything is a cJSON struct.
Get it parsed:
cJSON *root = cJSON_Parse(my_json_string);
This is an object. We're in C. We don't have objects. But we do have structs.
What's the framerate?
cJSON *format = cJSON_GetObjectItem(root,"format");
int framerate = cJSON_GetObjectItem(format,"frame rate")->valueint;
Want to change the framerate?
cJSON_GetObjectItem(format,"frame rate")->valueint=25;
Back to disk?
char *rendered=cJSON_Print(root);
Finished? Delete the root (this takes care of everything else).
cJSON_Delete(root);
That's AUTO mode. If you're going to use Auto mode, you really ought to check pointers
before you dereference them. If you want to see how you'd build this struct in code?
cJSON *root,*fmt;
root=cJSON_CreateObject();
cJSON_AddItemToObject(root, "name", cJSON_CreateString("Jack (\"Bee\") Nimble"));
cJSON_AddItemToObject(root, "format", fmt=cJSON_CreateObject());
cJSON_AddStringToObject(fmt,"type", "rect");
cJSON_AddNumberToObject(fmt,"width", 1920);
cJSON_AddNumberToObject(fmt,"height", 1080);
cJSON_AddFalseToObject (fmt,"interlace");
cJSON_AddNumberToObject(fmt,"frame rate", 24);
Hopefully we can agree that's not a lot of code? There's no overhead, no unnecessary setup.
Look at test.c for a bunch of nice examples, mostly all ripped off the json.org site, and
a few from elsewhere.
What about manual mode? First up you need some detail.
Let's cover how the cJSON objects represent the JSON data.
cJSON doesn't distinguish arrays from objects in handling; just type.
Each cJSON has, potentially, a child, siblings, value, a name.
The root object has: Object Type and a Child
The Child has name "name", with value "Jack ("Bee") Nimble", and a sibling:
Sibling has type Object, name "format", and a child.
That child has type String, name "type", value "rect", and a sibling:
Sibling has type Number, name "width", value 1920, and a sibling:
Sibling has type Number, name "height", value 1080, and a sibling:
Sibling has type False, name "interlace", and a sibling:
Sibling has type Number, name "frame rate", value 24
Here's the structure:
typedef struct cJSON {
struct cJSON *next,*prev;
struct cJSON *child;
int type;
char *valuestring;
int valueint;
double valuedouble;
char *string;
} cJSON;
By default all values are 0 unless set by virtue of being meaningful.
next/prev is a doubly linked list of siblings. next takes you to your sibling,
prev takes you back from your sibling to you.
Only objects and arrays have a "child", and it's the head of the doubly linked list.
A "child" entry will have prev==0, but next potentially points on. The last sibling has next=0.
The type expresses Null/True/False/Number/String/Array/Object, all of which are #defined in
cJSON.h
A Number has valueint and valuedouble. If you're expecting an int, read valueint, if not read
valuedouble.
Any entry which is in the linked list which is the child of an object will have a "string"
which is the "name" of the entry. When I said "name" in the above example, that's "string".
"string" is the JSON name for the 'variable name' if you will.
Now you can trivially walk the lists, recursively, and parse as you please.
You can invoke cJSON_Parse to get cJSON to parse for you, and then you can take
the root object, and traverse the structure (which is, formally, an N-tree),
and tokenise as you please. If you wanted to build a callback style parser, this is how
you'd do it (just an example, since these things are very specific):
void parse_and_callback(cJSON *item,const char *prefix)
{
while (item)
{
char *newprefix=malloc(strlen(prefix)+strlen(item->name)+2);
sprintf(newprefix,"%s/%s",prefix,item->name);
int dorecurse=callback(newprefix, item->type, item);
if (item->child && dorecurse) parse_and_callback(item->child,newprefix);
item=item->next;
free(newprefix);
}
}
The prefix process will build you a separated list, to simplify your callback handling.
The 'dorecurse' flag would let the callback decide to handle sub-arrays on it's own, or
let you invoke it per-item. For the item above, your callback might look like this:
int callback(const char *name,int type,cJSON *item)
{
if (!strcmp(name,"name")) { /* populate name */ }
else if (!strcmp(name,"format/type") { /* handle "rect" */ }
else if (!strcmp(name,"format/width") { /* 800 */ }
else if (!strcmp(name,"format/height") { /* 600 */ }
else if (!strcmp(name,"format/interlace") { /* false */ }
else if (!strcmp(name,"format/frame rate") { /* 24 */ }
return 1;
}
Alternatively, you might like to parse iteratively.
You'd use:
void parse_object(cJSON *item)
{
int i; for (i=0;i<cJSON_GetArraySize(item);i++)
{
cJSON *subitem=cJSON_GetArrayItem(item,i);
// handle subitem.
}
}
Or, for PROPER manual mode:
void parse_object(cJSON *item)
{
cJSON *subitem=item->child;
while (subitem)
{
// handle subitem
if (subitem->child) parse_object(subitem->child);
subitem=subitem->next;
}
}
Of course, this should look familiar, since this is just a stripped-down version
of the callback-parser.
This should cover most uses you'll find for parsing. The rest should be possible
to infer.. and if in doubt, read the source! There's not a lot of it! ;)
In terms of constructing JSON data, the example code above is the right way to do it.
You can, of course, hand your sub-objects to other functions to populate.
Also, if you find a use for it, you can manually build the objects.
For instance, suppose you wanted to build an array of objects?
cJSON *objects[24];
cJSON *Create_array_of_anything(cJSON **items,int num)
{
int i;cJSON *prev, *root=cJSON_CreateArray();
for (i=0;i<24;i++)
{
if (!i) root->child=objects[i];
else prev->next=objects[i], objects[i]->prev=prev;
prev=objects[i];
}
return root;
}
and simply: Create_array_of_anything(objects,24);
cJSON doesn't make any assumptions about what order you create things in.
You can attach the objects, as above, and later add children to each
of those objects.
As soon as you call cJSON_Print, it renders the structure to text.
The test.c code shows how to handle a bunch of typical cases. If you uncomment
the code, it'll load, parse and print a bunch of test files, also from json.org,
which are more complex than I'd care to try and stash into a const char array[].
Enjoy cJSON!
