CUER / Mbed 2 deprecated charger_code

Code to run on the charger board (used to charge the car from the mains).

Dependencies:   mbed CUER_CAN

CANParserCharger.cpp@1:0c77e20b4d4c, 2017-07-06 (annotated)

Revision:
1:0c77e20b4d4c
Child:
3:a7626dffb64a
Code majorly changed:; ; Structure changed significantly; All of the CAN-related functions, structures etc. added (but not yet tested); Still need to add some of the main program logic in terms of deciding when/when not to charge etc

Who changed what in which revision?
