Hello
They are using CY8CKIT-041-40XX at 5V(SW6 POS3), and I’m checking the raw data with CSX.
However, “Sensor Signal” does not change at all for two sensors out of the four.
When IDAC of the above sensor is confirmed with CapSense-Tuner, the IDAC value is “0”.(Enabel
IDAC auto-calibration is ON.)
Q1)
Could you please tell me the reason why the IDAC value was “0”? Is it due to sensor Pattern?Is it possible
to explain the cause from the calculation formula?
As a supplement;
Regarding the other two sensors which can be confirmed the “Sensor Signal”, these IDAC value are “127”.
Even if they change the value of “Tx clock” and “Number of sub-conversions”, “Sensor Signal” does not change( Keeping flat).
Best Regards
Arai
