   cd ..
   git clone https://github.com/commaai/c-capnproto.git
   cd c-capnproto
   git submodule update --init --recursive
   autoreconf -f -i -s
   CFLAGS="-fPIC" ./configure --prefix=/usr/local
   make -j4
   sudo make install

3. Clone openpilot if you haven't already

   git clone https://github.com/commaai/openpilot.git
   cd openpilot

   For Mac users

   Recompile longitudinal_mpc for mac

   Navigate to:

   cd selfdrive/controls/lib/longitudinal_mpc
   make clean
   make

4. Clone tools within openpilot, and install dependencies

   git clone https://github.com/commaai/openpilot-tools.git tools
   cd tools
   # sudo pip install if not using a venv
   pip install -r requirements.txt
   pip install -r ../requirements_openpilot.txt

5. Add openpilot to your PYTHONPATH.

   For bash users:

   echo 'export PYTHONPATH="$PYTHONPATH:<path-to-openpilot>"' >> ~/.bashrc
   source ~/.bashrc

6. Add some folders to root

   sudo mkdir /data
   sudo mkdir /data/params
   sudo chown $USER /data/params

7. Try out some tools!

Hardware needed: none

unlogger.py replays data collected with chffrplus or openpilot.

You'll need to download log and camera files into a local directory. Download these from the footer of the comma explorer or SCP from your device.

Usage:

python replay/unlogger.py <route-name> <path-to-data-directory>

#Example:

#python replay/unlogger.py '99c94dc769b5d96e|2018-11-14--13-31-42' /home/batman/unlogger_data

#Within /home/batman/unlogger_data:
#  99c94dc769b5d96e|2018-11-14--13-31-42--0--fcamera.hevc
#  99c94dc769b5d96e|2018-11-14--13-31-42--0--rlog.bz2
#  ...

# In another terminal you can run a debug visualizer:
python replay/ui.py   # Define the environmental variable HORIZONTAL is the ui layout is too tall

Hardware needed: panda, giraffe, joystick

Use the panda's OBD-II port to connect with your car and a usb cable to connect the panda to your pc. Also, connect a joystick to your pc.

joystickd.py runs a deamon that reads inputs from a joystick and publishes them over zmq. boardd.py sends the CAN messages from your pc to the panda. debug_controls is a mocked version of controlsd.py and uses input from a joystick to send controls to your car.

Usage:

python carcontrols/joystickd.py

# In another terminal:
selfdrive/boardd/boardd.py # Make sure the safety setting is hardcoded to ALL_OUTPUT

# In another terminal:
python carcontrols/debug_controls.py

Hardware needed: 2 x panda, debug board, EON.

It is possible to replay CAN messages as they were recorded and forward them to a EON.  Connect 2 pandas to the debug board. A panda connects to the PC, the other panda connects to the EON.

Usage:

# With MOCK=1 boardd will read logged can messages from a replay and send them to the panda.
MOCK=1 tools/replay/boardd.py

# In another terminal:
python replay/unlogger.py <route-name> <path-to-data-directory>

Hardware needed: EON, comma Smays.

You can connect your EON to your pc using the Ethernet cable provided with the comma Smays and you'll be able to stream data from your EON, in real time, with low latency. A useful application is being able to stream the raw video frames at 20fps, as captured by the EON's camera.

Usage:

# ssh into the eon and run loggerd with the flag "--stream". In ../selfdrive/manager.py you can change:
# ...
# "loggerd": ("selfdrive/loggerd", ["./loggerd"]),
# ...
# with:
# ...
# "loggerd": ("selfdrive/loggerd", ["./loggerd", "--stream"]),
# ...

# On the PC:
# To receive frames from the EON and re-publish them. Set PYGAME env variable if you want to display the video stream
python streamer/streamerd.py

• Documentation: code comments, better tutorials, etc..
• Support for other platforms other than Ubuntu 16.04.
• Performance improvements: the tools have been developed on high-performance workstations (12+ logical cores with 32+ GB of RAM), so they are not optimized for running efficiently. For example, ui.py might not be able to run real-time on most PCs.
• More tools: anything that you think might be helpful to others.
