Cycle_analyst_logger

Log the streaming data log output of a Grin Cycle Analyst V3 and optionally a Phaserunner and GPS

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

• Ruby ~2.4 or ~2.5
• Bundler

Bundler / Gemspec automatically pulls in all the dependencies

The usual Ruby install from github

git clone git@github.com:rberger/phaserunner.git
cd phaserunner
bundle install

• Delegates all Phaserunner operations to rberger/phaserunner phaserunner ruby gem
• Only tested with Navspark-BD GPS
• Now applies scaling factors to the Phaserunner data
• Log output file is CSV with CA, Phaserunner and GPS Data per line
• Also outputs the raw NMEA GPS file so that it can be read into Grin Trip Analyzer
• The to_ca_file command converts the default log output file to a CALog file suitable for inputing to Grin Trip Analyzer
• Sometimes the Trip Analyzer barfs on the NMEA file

Transform logs to CA format

NAME

SYNOPSIS
    cycle_analyst_logger [global options] to_ca_file log_filename

Deploy as usual. If you are not doing it from a git clone just want to install from Rubygems:

gem install phaserunner

A sample udev rules file is in resources/99-cycle_analyst.rules. It is based on the information from Persistent names for usb-serial devices

This one assumes we have the TTL to USB Cable based on the FTDI chipset like the USB Cables from Grin Tech We have one for the Cycle Analyst (CA) and one for the Phaserunner. If you always use the same cable with the CA and the other cable always for the Phaserunner (Label them). Then you can get away with using the serial numbers that the UDEV system sees to automatically link whatever USB port the cable is plugged into to the right /dev name.

The Navspark-BD GPS I used has a built in PL2303 chipset and doesn't seem to have a serial number like the FTDI chipsets does. So the setup assumes there is only one PL2303 USB and its the GPS.

There is a working systemd service unit file resources/cycle_analyst_logger.service. You can copy it into /lib/systemd/system and do a

systemctl daemon-reload to load it into systemd

• If you want it to start when the system is booted say:

  systemctl enable cycle_analyst_logger.service

• To disable:

  systemctl disable cycle_analyst_logger.service

• To start it manually (have to do this also the first time you do an enable and want it to run then):

  systemctl start cycle_analyst_logger.service

• You can check the status:

  systemctl status cycle_analyst_logger.service

• To see the logs:

  journalctl -u cycle_analyst_logger.service

This file assumed that rvm was installed in my home directory and an rvm wrapper was created so it the service unit file could just exec it. I am currently using Ruby 2.4.1.

The command used to create the wrapper was run as my normal user:

rvm alias create cycle_analyst_logger 2.4.1
