Arduino CAN bus logger

<mark>This is not longer being developed. The hardware issues were too difficult for my skill level to overcome.</mark>

Using an Arduino and a CAN shield connected to a vehicle, save as much information as possible to a SD card for processing later.

Usage

You can control serial output and the ability to have the Arduino record the time between messages. Setting SERIAL_ON to 1 enables serial output and doesn't take up extra memory thanks to the F() function. Setting TIMING_ON to 1 enables the processing and display of time between messages. Currently this uses 18 bytes when enabled.

Known issues

<mark>The log files in the repository are not valid, the code used to generate them was very flawed.</mark>

Currently using the Arduino Leonardo, I have a Mega and a Due on the way to play with.

Writing information to SD card takes time. - I need the ability to review the data later, it can't slow down my day job.

My code is horrible - I'm working on that. I have limited programming expierence and even less using GitHub or Arduino.
