# Installation on Windows10
|
|
|
|
1. Install python (windows automatically launches the installer if you type „python“ into the search field of the task bar)
|
|
2. Install Wireshark, this includes the pcap driver, which is necessary for low-level-network-interaction
|
|
3. Install git (recommended, but not necessary if you get the sources from git on an other way, e.g. via zip download)
|
|
4. Install mingw32 (if not included in the git installation)
|
|
|
|
5. Install python libraries
|
|
Attention: There are (at least) three different python-libs available for pcap:
|
|
- Libpcap
|
|
- Pylibpcap (But: only Python2)
|
|
- Pypcap (recommented on https://stackoverflow.com/questions/63941109/pcap-open-live-issue)
|
|
- Pcap-ct (https://pypi.org/project/pcap-ct/)
|
|
We use the last one.
|
|
python -m pip install --upgrade pcap-ct
|
|
This is fighting against the Libpcap-installation, so we need to deinstall the second:
|
|
python -m pip uninstall libpcap
|
|
Then again install pcap-ct, and finally add in the libpcap\_platform\__init__py the missing is_osx = False. (Is in the meanwhile fixed in the github repository.)
|
|
|
|
6. Clone the two github repositories, and compile the OpenV2Gx EXI decoder/encoder:
|
|
Create or use a folder, where you want to store the tools, e.g. C:\myprogs\ and open a command prompt there.
|
|
```
|
|
git clone http://github.com/uhi22/pyPlc
|
|
git clone http://github.com/uhi22/OpenV2Gx
|
|
cd OpenV2Gx\Release
|
|
mingw32-make all
|
|
```
|
|
|
|
(this may take some minutes)
|
|
|
|
Test the EXI decoder/encoder
|
|
```
|
|
cd myprogs\OpenV2Gx\Release
|
|
OpenV2G.exe DD809a0010d0400000c800410c8000
|
|
OpenV2G.exe EDB_5555aaaa5555aaaa
|
|
```
|
|
This should run without error and show the decoded/encoded data in the command window.
|
|
|
|
Now we go to the python part.
|
|
```
|
|
cd $home/myprogs/pyPlc
|
|
```
|
|
|
|
Check python version
|
|
|
|
`python --version`
|
|
reports e.g. 3.9.2.
|
|
|
|
7. Edit the configuration file
|
|
The file pyPlc.ini can be changed in a way to fit the needs. E.g. the default behavior (PevMode or EvseMode) can be configured,
|
|
for the case that the pyPlc script is called without command line arguments.
|
|
|
|
8. Edit the MAC of the network interface
|
|
(Not clear, whether this is still needed. Todo: optimize code and description...)
|
|
Find out the MAC address of the laptops ethernet interface, by running `ipconfig -all` in the command line.
|
|
Edit the file addressManager.py and write your MAC into the MAC_LAPTOP variable.
|
|
|
|
9. Perform a simulated charging session
|
|
Open two command line windows.
|
|
In one command line, start the charger (EVSE) in simulation mode: `python pyPlc.py E S`.
|
|
In the other window, start a car (PEV) in simulation mode: `python pyPlc.py P S`.
|
|
Each of it should show a window where we can see how the charging works.
|
|
|
|
10. Perform a real charging session
|
|
If you have set the intended mode in the pyPlc.ini, simply call `python pyPlc.py`.

## Driver for the USB-to-Serial brigde
|
|
|
|
(This is optional and only necessary, if devices like Dieter or display is planned to be used on a USB-to-serial converter.)
|
|
For the USB-to-Serial bridge, which is sold as CP2102, the Windows 10 tries to install the driver when plugged-in. But
|
|
the device did not work together with the driver which windows found automatically. A root cause may be, that the
|
|
device is not an original CP2102, but a clone. Finally found a driver on https://www.pololu.com/docs/0J7/all, which works.
