Megasquirt Node Logger

This project is intended to be a serial data logger reimplementation for megasquirt based projects. My plan is to install this on a raspberry pi running a wpe buildroot (fast boot time a handful of seconds) The buildroot contains a webkit browser and can display a gauge cluster built in react.

Features

• Parses megasquirt ini files (reasonably well) to enable customized field logging
• Pluggable architecture enabling single input multiple output of megasquirt data. Current outputs:
  • Log to file (msl format - works with MegalogViewer)
  • Websocket streaming (for another project i'm working on for react based gauge cluster)

TODO

• Automatically start new log file on disconnect/reconnect
• Consider doing a better job at parsing the insanity that is the MS ini files (maybe)
• Better/more error handling

Installation

If you don't have yarn you can use npm I guess

• yarn install

Configuration (optional)

• Requires: cpp to parse the macros in the MS ini files
• Copy your ini file to the config directory
• cd config
• Run ./preprocess_config.sh <config_file_name> mainController.ini
• This will enable celsius mode, edit preprocess_config.sh if you don't want this, it's a very basic script

Usage

• Basic: yarn start -s <serial_port>
• With websocket server on port 8088: yarn start -s <serial_port>

yarn start --help

Usage: index [options]
