CAPTIVATE-FR2676: CAPTIVATE-METAL about measurement time adjustment

Hello Cash Hao,

How exactly do I change the measurement resolution and conversion frequency in ccstudio?

Currently, we are measuring at the fastest setting of 0.145msec, but we would like to quadruple it to 0.58msec.

Hello Cash Hao,

I would like to set the measurement time for one button to about 200us, and measure one button three times in a row to set the measurement time to about 600us.

Could you please explain the following two points?
1. Measurement time for one button is about 200us
2. 3 consecutive measurements with one button

Ryuto

Hi,

The current measurement time for one button is 0.145ms = 145us. Do you want to increase the time to 200us? 

3 consecutive measurements with one button. It could be possible. Let me check with the experts and give you feedbacks. 

Best regards,

Cash Hao

Hello Cash Hao,

>Do you want to increase the time to 200us?
Yes

Ryuto

Hi,

Double check one more thing, you want to increase the time exactly at 200us or roughly around 200us?

Hi,

I get some feedbacks from the Captivate expert. 

1. We can not make the measurement time at exactly 200us. Because the count value is going to change when the button is under press. The measurement time will change due to the change of count value.

2. You can measurement time for one button is about 200us and then 3 consecutive measurements with one button. You need to change the code to do that. You can generate code in the Design center for a total of 4 touch IO. And then change the 3rd and 4th touch IO as the 2nd touch IO in the software.

ConversionCount=250 on the left

ConversionCount=500 on the right

The measurement time has been changed, but is it impossible to set it to 200us?

Can I get specific instructions on how to do this?

Hi,

1. You can set to 200us. However, when you touch that button, the measurement time is going to change. 

2. Let me check with the experts and check if we can provide a demo for your application. 

Best regards,

Cash Hao

Hello Cash Hao,

1. I understand.Thank you!

2. Thank you for providing the demo.
