void ChargeCheck

(

void

)

Todo:

Whenever you move 2X the capacity, either into or out of the pack, you are supposed to increment the CycleCount variable. You do NOT have to have hit both FULL and EMPTY limits.

Todo:

Re-enable the Wdog for your final code. It is disabled here to allow debugging to take place without interference.

void MasterSMBusCheck

(

ResetTimer

)

Todo:

Only a very basic charge control algorithm has been implemented. It uses the charge state to decide. It is up to the designer to implement a more sophisticated charging algorithm.

Todo:

The following Cell temperature checking is disabled since it is left to the user to choose a specific Thermistor.
