Example:

TS_TemperatureType strTestTemperature;

...

/* Write the following value for Over-Limit register: +75.5° C

strTestTemperature.TS_Sign

= TS_PLUS_SIGN;

strTestTemperature.TS_IntegerValue = 75;

strTestTemperature.TS_DecimalValue = 5;

/* 0 or 5 only */

pObjTempSensor->SetTempOverLimit (pObjTempSensor,

&strTestTemperature);

TempSensor:: GetTempOverLimit API function

Table 19 describes the GetTempOverLimit function of the TempSensor structure.

Example:

TS_TemperatureType* pStrTemperature;

/* Get the Over-Limit temperature structure pointer forcing a STLM75

pStrTemperature = pObjTempSensor->GetTempOverLimit (pObjTempSensor,

TS_TRUE);

Table 19.

Behavior description

Return the Over-limit 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

Over-limit 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 (…);
