ToCoNet_u16RcCalib()

Explanation

Calibrate the RC timer.

• Performing a calibration

• Getting calibration values

• Setting the calibration values

You can also use ToCoNet_u16GetRcCalib() to get the calibration values.

Use of external oscillator at 32768Hz

No calibration is required and a fixed value of 9766 (32000/32768) counts is specified. Use cbAppColdStart() as shown in the following example.

// Only valid for TWENET library 1.2.0 and later
void cbAppColdStart(bool_t bAfterAhiInit)
{
	if (!bAfterAhiInit) {
		ToCoNet_REG_MOD_ALL();
	} else {
		ToCoNet_Event_Register_State_Machine(vProcessEvCore);
		...
		// Omit calibration at system start-up
		sToCoNet_AppContext.bSkipBootCalib = TRUE;
		// Setting fixed values (v1.2 and later)
		ToCoNet_u16RcCalib(9766);
	}
}

void vProcessEvCore(
        tsEvent *pEv,
        teEvent eEvent,
        uint32 u32evarg) {
        
     if (eEvent == E_EVENT_START_UP) { //At system start-up
     	// Setting of fixed values
 	ToCoNet_u16RcCalib(9766);
     }
 }

Argument

Type	Name	Value	Remark
​uint16	​u16val	0	Calibration is carried out. Calibration takes less than 1 ms, but some time is required.
		5000-15000	Sets the calibration value.
		0xFFFF	Retrieves the set value.

Returns

Type	Remark
​uint16	If the argument u16val == 0xFFFF, the current setting value is returned. Otherwise undefined.​
