-Nanopb example "simple" using CMake
-=======================
-
-This example is the same as the simple nanopb example but built using CMake.
-
-Example usage
--------------
-
-On Linux, create a build directory and then call cmake:
-
- nanopb/examples/cmake_simple$ mkdir build
- nanopb/examples/cmake_simple$ cd build/
- nanopb/examples/cmake_simple/build$ cmake ..
- nanopb/examples/cmake_simple/build$ make
-
-After that, you can run it with the command: ./simple
-
-On other platforms supported by CMake, refer to CMake instructions.

-Nanopb example "network_server"
-===============================
-
-This example demonstrates the use of nanopb to communicate over network
-connections. It consists of a server that sends file listings, and of
-a client that requests the file list from the server.
-
-Example usage

-Details of implementation
--------------------------
-fileproto.proto contains the portable Google Protocol Buffers protocol definition.
-It could be used as-is to implement a server or a client in any other language, for
-example Python or Java.
-
-fileproto.options contains the nanopb-specific options for the protocol file. This
-sets the amount of space allocated for file names when decoding messages.
-
-common.c/h contains functions that allow nanopb to read and write directly from
-network socket. This way there is no need to allocate a separate buffer to store
-the message.
-
-server.c contains the code to open a listening socket, to respond to clients and
-to list directory contents.
-
-client.c contains the code to connect to a server, to send a request and to print
-the response message.
-
-The code is implemented using the POSIX socket api, but it should be easy enough
-to port into any other socket api, such as lwip.

-Nanopb example "simple"
-=======================
-
-This example demonstrates the very basic use of nanopb. It encodes and
-decodes a simple message.
-
-The code uses four different API functions:
-
- * pb_ostream_from_buffer() to declare the output buffer that is to be used
- * pb_encode() to encode a message
- * pb_istream_from_buffer() to declare the input buffer that is to be used
- * pb_decode() to decode a message
-
-Example usage
--------------
-
-On Linux, simply type "make" to build the example. After that, you can
-run it with the command: ./simple
-
-On other platforms, you first have to compile the protocol definition using
-the following command::
-
- ../../generator-bin/protoc --nanopb_out=. simple.proto
-
-After that, add the following four files to your project and compile:
-
- simple.c simple.pb.c pb_encode.c pb_decode.c
-

-Nanopb example "using_double_on_avr"
-====================================
-
-Some processors/compilers, such as AVR-GCC, do not support the double
-datatype. Instead, they have sizeof(double) == 4. Because protocol
-binary format uses the double encoding directly, this causes trouble
-if the protocol in .proto requires double fields.
-
-This directory contains a solution to this problem. It uses uint64_t
-to store the raw wire values, because its size is correct on all
-platforms. The file double_conversion.c provides functions that
-convert these values to/from floats, without relying on compiler
-support.
-
-To use this method, you need to make some modifications to your code:
-
-1) Change all 'double' fields into 'fixed64' in the .proto.
-
-2) Whenever writing to a 'double' field, use float_to_double().
-
-3) Whenever reading a 'double' field, use double_to_float().
-
-The conversion routines are as accurate as the float datatype can
-be. Furthermore, they should handle all special values (NaN, inf, denormalized
-numbers) correctly. There are testcases in test_conversions.c.

-Nanopb example "using_union_messages"
-=====================================
-
-Union messages is a common technique in Google Protocol Buffers used to
-represent a group of messages, only one of which is passed at a time.
-It is described in Google's documentation:
-https://developers.google.com/protocol-buffers/docs/techniques#union
-
-This directory contains an example on how to encode and decode union messages
-with minimal memory usage. Usually, nanopb would allocate space to store
-all of the possible messages at the same time, even though at most one of
-them will be used at a time.
-
-By using some of the lower level nanopb APIs, we can manually generate the
-top level message, so that we only need to allocate the one submessage that
-we actually want. Similarly when decoding, we can manually read the tag of
-the top level message, and only then allocate the memory for the submessage
-after we already know its type.
-
-
-Example usage
--------------
-
-Type `make` to run the example. It will build it and run commands like
-following:
-
-./encode 1 | ./decode
-Got MsgType1: 42
-./encode 2 | ./decode
-Got MsgType2: true
-./encode 3 | ./decode
-Got MsgType3: 3 1415
-
-This simply demonstrates that the "decode" program has correctly identified
-the type of the received message, and managed to decode it.
-
-
-Details of implementation
--------------------------
-
-unionproto.proto contains the protocol used in the example. It consists of
-three messages: MsgType1, MsgType2 and MsgType3, which are collected together
-into UnionMessage.
-
-encode.c takes one command line argument, which should be a number 1-3. It
-then fills in and encodes the corresponding message, and writes it to stdout.
-
-decode.c reads a UnionMessage from stdin. Then it calls the function
-decode_unionmessage_type() to determine the type of the message. After that,
-the corresponding message is decoded and the contents of it printed to the
-screen.
