你好
他们使用CY8CKIT-041-40XX在5V(SW6 POS3),并且我用CSX检查原始数据。
然而,对于四个传感器中的两个传感器来说,“传感器信号”根本不会改变。
当用CapSense Tuner确定上述传感器的IDAC时,IDAC值为“0”(EnabelIDAC自动校准)。
Q1)
你能告诉我IDAC值是“0”的原因吗?是由于传感器模式造成的吗?从计算公式中解释原因是可能的吗?
作为补充;
对于其他两个可以确认为“传感器信号”的传感器,这些IDAC值为“127”。
即使它们改变了“TX时钟”和“子转换数”的值,“传感器信号”也不会改变(保持平坦)。
最好的问候

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).
