|
* Twizy Virtual BMS Example: Template
|
|
* ==========================================================================
|
|
*
|
|
* - You can register some callbacks with the Virtual BMS, this
|
|
* template contains prototypes for all of them as well as the
|
|
* basic initialization and integration.
|
|
*
|
|
* Note: if you don't need a callback, you don't need to define and attach it.
