This is for the Longan Labs ObD-II CAN bus GPS dev kit, V2.0.
I had to do some reverse engineering of the board because the power control pin and chip select pins are not documented and the examples from Longam Labs are incorrect.
This is a work in progress.
feature goals are:
- record GPS and CAN frames to a SavvyCAN conpatible CSV file
- automatically delete old logs to free up room for new ones
