Function Documentation

uint8_t TM_CPULOAD_GoToSleepMode	(	TM_CPULOAD_t *	CPU_Load,
		TM_LOWPOWERMODE_t	PowerMode
	)

Goes to low power mode and measures sleeping time and working time using DWT cycle counter.

Note

You need wake up source, otherwise you might stay forever inside low power mode

Parameters

*CPU_Load	Pointer to TM_CPULOAD_t structure
PowerMode	Select power mode you want to use for measure CPU load. Valid parameters are: TM_LOWPOWERMODE_SleepUntilInterrupt: Go to sleep mode with __WFI() instruction TM_LOWPOWERMODE_SleepUntilEvent: Go to sleep mode with __WFE() instruction

Return values

CPU	load value updated status. 0: CPU load value is not updated, still old results > 0: CPU load value is updated

uint8_t TM_CPULOAD_Init

(

TM_CPULOAD_t *

CPU_Load

)

Initializes DWT functionality for sleep counter and prepares everything for CPU LOAD measurement.

Parameters

*CPU_Load

Pointer to empty TM_CPULOAD_t structure

Return values

Returns

DWT counter status: 0: DWT counter has not started, measurement will fail > 0: DWT counter has started, everything OK
