General Notes

These are my best guesses at the “types” of data

• Boolean (8-bit)

  • for example, ACK, lights_state

  • working/not working, on/off, etc

  • ack = acknowledgement, basically seeing if the thing is working/on

  • state = on/off

• Key-value pairs 

  • for example, module_id (key) & temperature for that module (value)

  • Keys are 8 or 16 bit depending on the number of keys

  • Values are 16 or 32 bit

  • For each value, it’d be nice to have units (ie V, mA...)

• Values (16 or 32 bit)

  • ie aggregate battery pack voltage, current

  • For each value, it’d be nice to have units (ie V, mA...)

• State/Fault number (16-bits) (each value corresponds to a drive state or fault)

  • Would like to have list of driver states, and faults names 

  • ie Driver States, State Transition Faults, Solar faults
