Defines
#define	EXPORT
#define	SUM_COUNT   20U
	This value defines the array size of mg_au16Data and thus the span of time used to calculate the motor current sum.
#define	AVG_COUNT   8U
	This value defines the array size of mg_au16AvgData and thus the span of time used to calculate the average motor current.
Functions
void	current_Init (void)
	Init function of module current.c.
void	current_Update (void)
	Reads the motor current load.
void	current_UpdateSum (void)
	Updates the motor current load sum.
void	current_UpdateAvg (void)
	Updates the average motor current.
UINT16	current_GetAvg (void)
	Returns the average motor current value.
UINT16	current_GetValue (void)
	Returns the latest value for motor current.
UINT16	current_GetSum (void)
	Returns the latest value for motor current sum.
Variables
static UINT16	mg_u16Value = 0U
	UINT16 variable to store the latest current ADC value.
static UINT16	mg_au16Data [SUM_COUNT]
	UINT16 variable to store the ADC values of motor current for accumulation.
static UINT16	mg_au16AvgData [AVG_COUNT]
	UINT16 variable to store the ADC values of motor current for averaging.
static UINT16	mg_u16Sum = 0U
	UINT16 variable to store the current sum.
static UINT8	mg_u8SumIdx = 0U
	UINT8 index variable for array mg_au16Data.
