# Getting started
## Use of CAN config generator
### Build requirements
* CMake version 3.0 or later
-* G++, Clang++ or any C++11 complient compiler.
-* Boost
- * filesystem
- * program\_options
- * system
-
-You can install any of these using your package manager. For instance, inside the iotbzh's docker image, you must enter this command :
-
-```bash
-$ sudo apt-get update
-$ sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-program-options-dev
-```
-
-You may want to install `libboost-all-dev` to get all boost components even if it's not required.
+* G++, Clang++ or any C++11 compliant compiler.
### Compile
```bash
$ export PATH=$PATH:/xdt/sdk/sysroots/x86_64-aglsdk-linux/usr/bin
-$ git clone https://github.com/iotbzh/can-config-generator.git
-$ cd can-config-generator
-$ mkdir build
+$ export WD=$(pwd)
+$ git clone https://github.com/iotbzh/CAN_signaling
+$ export GENERATOR=${WD}/CAN-signaling/CAN-config-generator
+$ mkdir -p build
$ cd build
$ cmake -G "Unix Makefiles" ..
$ make

+### Available decoder
+
+You can use some basic decoder provided by default by the binding which are:
+
+* decoder_t::noopDecoder : Default decoder if not specified, return raw value from signal's bitfield.
+* decoder_t::booleanDecoder : Coerces a numerical value to a boolean.
+* decoder_t::stateDecoder : Find and return the corresponding string state for a CAN signal's raw integer value.

### Generating JSON from Vector CANoe Database
-> **CAUTION** This chapter has not been tested since we haven't necessary automotive tools for that.

-If you use Canoe to store your `gold standard` CAN signal definitions, you may be able to use the OpenXC `xml_to_json.py` script to make your JSON for you. First, export the Canoe .dbc file as XML - you can do this with Vector CANdb++. Next, create a JSON file according to the format defined above, but only define:

```
-If you omit the `-o` option, then code is generated on the stdout.
-You also can specify a header and a footer file.
-These files must be valid C++ fragment as long as they will be inserted as is.

Use the `-h` option to display help.
> **CAUTION:** Each `diagnostic_message` must define the same `bus` as the binding will use only one bus.
### Supported OpenXC items
-About now, compliance with OpenXC reference is in progress, can-config-generator and CAN\_signaling will implement them soon.
+About now, compliance with OpenXC reference is in progress, can-config-generator and CAN\_signaling will implement them soon.
`initializers`, `loopers`, `commands` and `handlers` nodes are ignored for now.
This generator will follow OpenXC support status of the low level CAN signaling binding.
> **NOTE**: The `buses` item will not be supported by this generator because the binding use another way to declare and configure buses. Please refer to the binding's documentation.
## Compile and install the binding
+Clone the binding repository, copy the generated file and updated the git submodules.
-With an AGL SDK environment correctly configured and **sourced**, I suggest you to set the TARGET variable in the root CMakeLists.txt file if you have an AGL target already running in your network.
+Execute the following commands from this repository:
-Then you can directly build and install the binding and source directory on your target system.
+```bash
+$ cd $WD/CAN_signaling/CAN-binder
+$ cp ${GENERATOR}/build/configuration-generated.cpp ../low-can-binding/binding
+```
-Execute these commands to get your binding compile :
+### Installation
```bash
$ mkdir build
$ cd build
$ cmake ..
$ make
+$ make widget
```
-And if you have set TARGET variable, you can install it on your AGL system :
-
-```bash
-$ make install
-[ 16%] Built target bitfield
-[ 27%] Built target isotp
-[ 40%] Built target openxc
-[ 48%] Built target uds
-[ 97%] Built target low-can-binding
-[100%] Built target widget
-Install the project...
--- Install configuration: ""
-true
-{ "added": "low-can-binding@0.1" }
-```
-
-It's possible that you'll see the following message :
-
-```bash
-Error org.freedesktop.DBus.Error.Failed: "system error"
-```
-
-It's because installation remove the binding before installing it.
-
-If it is the first time that you make the installation then you'll have this message in place of _**true**_.
-
To install it manually, you need to copy the _low-can-binding.wgt_ file on your target, then from it execute the following commands :
On your host, to copy over the network :
```bash
-$ scp low-can-binding.wgt root@<target_IP>:~
+$ scp low-can-project.wgt root@<target_IP>:~
```
-On the target, assuming _**wgt**_ file is in the root home directory :
+On the target, assuming _**wgt**_ file is in the root home directory:
```bash
-~# afm-util install low-can-binding.wgt
-{ "added": "low-can-binding@0.1" }
+# afm-util install low-can-binding.wgt
+{ "added": "low-can-project@0.1" }
