CANopener

An ESP32-based project for interfacing with the automotive CAN bus protocol.

Why use this library?

ESP-IDF based, built for speed and extensibility - uses the built-in CAN conntroller of the ESP32
Arduino Core and Library support
Compatibility: v3.3.2 of the ESP-IDF is used to ensure compatibility between all major ESP32 frameworks (IDF, ADF, MDF, DSP, Arduino)

Installation

Make sure you are using a Python2 environment in your terminal. See Python Installation section for details on how to do this.
Install ESP-IDF at the v3.3.2 release (if you have not already)
1. Check you current version git describe --always --tags --dirty
2. If in doubt, delete your ESP-IDF folder and fresh install
  git clone -b v3.3.2 --recursive https://github.com/espressif/esp-idf.git
Download this repository git clone --recursive https://github.com/oliverjc/CANopener.git
make menuconfig to configure the project
make -j17 to build (change the number to however many cores your computer has +1)

Install home-brew
Install Anaconda brew cask install anaconda
Add Anaconda path to your bash profile. Just insert this line anywhere in your .zshrc or .bashprofile file within your user directory export PATH=“/usr/local/anaconda3/bin:$PATH”
Initialise Anaconda for whatever shell you are using. conda init <SHELL_NAME> You're probably using either bash or zsh e.g. conda init zsh
Install CCACHE brew install cache
Create a Python 2 Environment conda create -—name py2 python=2.7
Activate that environment conda activate py2
Add Alias to make activating our environment a lot easier. Add this line to your .zshrc or .bashprofile file. alias pyinit="conda deactivate && conda activate py2” Now whenever we want to activate our python2 environment we simply have to call pyinit To revert to our default environment, just use conda deactivate
