Example:

TS_I2C_SettingsType TempSensorI2C_Settings;

/* Enable I2C2 clock */

RCC_APB1PeriphClockCmd(RCC_APB1Periph_I2C2, ENABLE);

/* I2C Peripheral settings initialization */

TempSensorI2C_Settings.TS_I2C_Ptr

= I2C2;

TempSensorI2C_Settings.TS_I2C_Clock

= 0x90;

TempSensorI2C_Settings.TS_I2C_Address = 400000;

pObjTempSensor->SetI2C_Settings(pObjTempSensor,

&TempSensorI2C_Settings);

TempSensor:: SetSignals API function

Table 9 describes the SetSignals function of the TempSensor structure.

This function is called by the TempSensor:Init function during the initialization phase,

therefore it’s not necessary to directly call it. The final application can specifically call this

function in order to change the microcontroller signal (port, pin, mode) settings after

initialization.
