* Only turn on wifi if not eon * Dont disable ESP in early * Allow CAN to be turned off - CAN is turned off via timeout - CAN is turned on when either try to transmit or can is received - If only transmit is asleep, all messages should send okay - If receive is alseep, will miss first message while waking up - Sometimes will report error on second message while CAN perif wakes up - Saves 130mW! * Power Saver Mode - Gray Panda power consumption 650mw -> 325mW - Turns off CAN, GMLAN, LIN, GPS when no activity for 10s - No acitvity is no CAN send, CAN Recv, Write to GPS * Fix power_saving to better turn off can - On some cars when the can is turned off, it triggers a wakeup. Delaying the automatic wakeup seems to fix this * Don't save power in pedal * Cleanup power saving
