Hi,
With respect to the MSP430 Captivate design, the Users Guide
don't have details of some parameters like Delta.
Could you please let us know how if there is any equation to find out delta.
Can we use below equation from previous Capacitive guide?
delta = base - measurement
The config.c has definition for sensorpad as shown below,
but we couldn't understand how the Delta and Base values are calculated
in this function.
u
// Sensor: keypadSensor, Element: E00
uint16_t keypadSensor_E00_RawCnts[CAPT_SELF_FREQ_CNT];
tCaptivateElementTuning keypadSensor_E00_Tuning[CAPT_SELF_FREQ_CNT];
tElement keypadSensor_E00 =
{
.ui8RxPin = 0,
.ui8RxBlock = 0,
.ui8TouchThreshold = 10,
.pRawCount = keypadSensor_E00_RawCnts,
.pTuning = keypadSensor_E00_Tuning,
};
Please let us know if there is more details on Delta and Base calculations.
Best Regards
Kummi
