◆ BMS_STATEMACHINE_TASK_CYCLE_CONTEXT_MS

#define BMS_STATEMACHINE_TASK_CYCLE_CONTEXT_MS   (10u)

TODO.

This define MUST represent the cycle time of the task in which context the functions run, e.g., if the BMS_Trigger() is running in the 10 ms task then the define must be set to 10. This sets the minimum time between two subsequent executed states/substates. Define is only used for compile-time assertion, it has no programatic influence on the actual code.
