Design Notes

• Main initializes killswitch, current_sense, battery_heartbeat, cell_sense, and fan_control. 
• Killswitch, current_sense, and cell_sense need direct access to battery_heartbeat in order to quickly raise or clear faults.

...

• Initializes other modules, initializes CAN and other modules
• Stores the most updated measurements
• Current
• Cell voltages
• Cell temps
• Relay state
• Fan speed

Data_tx

• periodically transmits over CAN the current, cell voltages, cell temps, and relay states
• Note: may be switched to an alternate form of communication, pending raspberry pi integration

Killswitch

• Initializes a debounced GPIO pin to handle killswitch presses
• Exposes init
