Welcome to panda
panda is the nicest universal car interface ever.
It supports 3x CAN, 2x LIN, and 1x GMLAN. It also charges a phone. On the computer side, it has both USB and Wi-Fi.
It uses an STM32F413 for low level stuff and an ESP8266 for Wi-Fi. They are connected over high speed SPI, so the panda is actually capable of dumping the full contents of the busses over Wi-Fi, unlike every other dongle on amazon. ELM327 is weak, panda is strong.
It is 2nd gen hardware, reusing code and parts from the NEO interface board.
To install the library:
# pip install pandacan
See this class for how to interact with the panda.
For example, to receive CAN messages:
>>> from panda import Panda >>> panda = Panda() >>> panda.can_recv()
And to send one on bus 0:
>>> panda.can_send(0x1aa, "message", 0)

Software interface support
As a universal car interface, it should support every reasonable software interface.
- board -- Code that runs on the STM32
- boardesp -- Code that runs on the ESP8266
- drivers -- Drivers (not needed for use with python)
- python -- Python userspace library for interfacing with the panda
- tests -- Tests and helper programs for panda
Programming (over USB)
To print out the serial console from the STM32, run tests/debug_console.py
To print out the serial console from the ESP8266, run PORT=1 tests/debug_console.py
When a panda powers up, by default it's in "SAFETY_NOOUTPUT" mode. While in no output mode, the buses are also forced to be silent. In order to send messages, you have to select a safety mode. Currently, setting safety modes is only supported over USB.
Safety modes can also optionally support "controls_allowed", which allows or blocks a subset of messages based on a piece of state in the board.
