TickTock 4:8d7759f4fe7a 3 //To Do:
TickTock 33:a277743ebdeb 4 // * USB device detect
TickTock 33:a277743ebdeb 5 // * Ability to update binary from the thumb-drive (requires file timestamp)
TickTock 33:a277743ebdeb 6 // * Audible friction brake feedback
TickTock 33:a277743ebdeb 7 // * User-configurable watchpoint
TickTock 33:a277743ebdeb 8 // * Better graphical DTE display with historic efficiency information considered and displayed
TickTock 33:a277743ebdeb 9 // * Add 50% charge option
TickTock 33:a277743ebdeb 10 // * Tire Pressure Sensor display
