Hi,

We would like to confirm for Capsense of PSoC4L

We understood that PSoC4L has dual Capsese.

Maximum lements of one linear slider is 32.

Of course, you can set a 32 elements slider on a single CapSense component.

However, Use two CapSense components,
If you set the 32 element slider to each CapSense, it will be a Build error.

Build error will not occur if 16 elements are set.

Do you have any information on the number of CapSense elements?

The following is for reference,

One CapSense : 32 elements slider x2 : NG

One CapSense : Bottun x32 and 32 elements one slider : NG

One CapSense : Bottun x16 and 32 elements one slider : OK

One CapSense : 16 elements slider and 32 elements slider : NG

Dual CapSense : Each 16 elements slider and 32 elements slider : OK

Dual CapSense : Each 32 elements slider and 32 elements slider : NG

Regards,

Hi MaMi_1205306​-san,

The issue is suspected to be because of buffer overflows in the PSoC Creator build. We have not been able to identify the exact root cause yet but we have a workaround for this issue. Reducing the length of the slider name helped resolve the issue in our side. Could you please use a shorter variable name for the sliders (around 5 characters) and check if the project builds successfully?

Regards,
