// main.cpp // //To Do: // * USB device detect // * 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 additional 79b bank readouts // * Add ability to transfer settings config file to/from USB // * Move log dump to ISR (but CAN RX at higher priority) #include "mbed.h" #include "CAN.h" #include "beep.h" #include "ff.h" #include "PowerControl.h" #include "EthernetPowerControl.h" #include "utility.h" #include "displayModes.h" #include "TOUCH_TFTx2.h" char revStr[7] = "111";
