Example:

TS_TemperatureType* pStrTemperature;

/* Get the Hysteresis temperature structure pointer forcing a STLM75

pStrTemperature = pObjTempSensor->GetTempHysteresis

(pObjTempSensor, TS_TRUE);

TempSensor:: SetTempOverLimit API function

Table 18 describes the SetTempOverLimit function of the TempSensor structure.

Behavior description

Return the Hysteresis temperature structure pointer.

Input parameter {x}

pThis - Object pointer;

bForceRegisterRead - if TS_TRUE reads the value from the register

otherwise the last read value returns

Output parameter {x}

None

Return value

Hysteresis temperature pointer if successful, TS_NULL_PTR otherwise

Required preconditions

NewTempSensorObj, TempSensor:: Init functions must have been called

before.

Called functions

HAL function:

TS_ErrStatus TS_SetPointerRegister(…);

TS_ErrStatus TS_FillDataFromRegister (…);
