...

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

Killswitch

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

Battery_heartbeat

• Periodically transmits battery status and receives acks
• Exposes ability to raise and clear faults based on a bitset, and init
• Opens relays in case of fault and updates relay state

Relay_control

• Statically sets relay state, updates stored state, and returns whether the relay state set was successful.
• Exposes set_relay_state
• Note: may need to have a delay when setting relay states to avoid drawing too much current at once

Current_sense

• Registers an interrupt to update the stored current value based on ADC reading
• If the updated current value is above a threshold, raise overcurrent fault
• If the overcurrent fault bit is set and the updated current value is below the threshold, drop the fault bit
• Exposes init

Ads_1259

• Driver for the ADS1259 24 bit ADC
• Exposes ltc_adc_register_callback

Cell_sense

• To be ported from MSXII firmware.
• Raises / lowers faults similar to current_sense, including overcharge, over temperature, over current, under charge

Fan_control

• Periodically updates the fan speed based on the temperature
• Uses an offset linear fan control curve based on the desired operating temperature of the battery (refer to datasheet)
• Exposes init
