// main.cpp
//To Do:
// * USB device detect
// * Enable file timestamps
// * Audible friction brake feedback
// * User-configurable watchpoint
// * Add 50% charge option
// * Tire Pressure Sensor display
// * Fix bug in playback while connected to canbus (hangs)
// * Force regen display to zero when in neutral
// * Add coasting regen to regen/braking display
// * Change semilog efficiency graph to linear with 10 minute values
// * Add Trip meter (kWh and efficiency for current trip)
// * Make unique sound when log file write fails and logging disabled
// * Make display updates interruptable for log writes
// * Add additional 79b bank readouts
// * Ignore the missing 4th pemperature sensor on 2013 models
// * Add ability to transfer settings config file to/from USB
// * Add once-on-powerup/powerdown log
// * Move log dump to ISR (but CAN RX at higher priority)
