Design:
- One FSM for power management
- One FSM per each power transition (off → on, off→ battery)
To-do:
- Don't know how the precharge method happens in terms of the car:
- ask Micah Black
- Look up MS12
- ask the ms12 people
- Need to bring in charging into the equation.
- Add a watchdog timer for precharge.
CAN Messages:
| Destination | Purpose | Message ID |
|---|---|---|
| Front Power Distribution | Turn on Driver Display during power on (to possibly show error messages) | |
| Rear Power Distribution | Turn on BMS Carrier | |
| Get Aux Status | Simple message, acked with OK if the aux battery level is enough. | |
| Get DCDC Status | Simple message, acked with OK if DCDC has switched. | |
| Begin Pre-Charge | How do we pre-charge? for now, assuming a simple message with ack. | |
| Pre-Charge Complete | Sent with Ack after precharge is complete. |

- Will only be triggered if pedal is pressedturn on if pressed,
- Press button
- Controller board sends signal through CAN
