The same question is written in English and Japanese.

・English

I think the horizontal axis of CapSense _ Tuner is the number of samples.
I would like to sample as soon as possible. Which parameter should I change?

・Japanese
CapSense_Tunerの横軸はサンプリング回数かと思います。
なるべく早くサンプリングしたいのですが、どのパラメータを変更すればいいですか?

Regards

The sampling rate would be affected by scanning frequency and I2C speed.

And scanning frequency is defined by scanning resolution and modulator clock.

However, please note that modulator clock influences capsense performance.

So you have to tune capsense based on your system requirement.

Hello RyYo_1406951

You can increase the number of samples by changing the "number of samples" field in the Tuner GUI.pastedImage_0.png
