PSoC 4

Hi Everyone,

I am using the CY8C4125LQI-S432 for my project, and I am trying to use CapSense Tuner to fine tune my CapSense response.

But whenever I start the CapSens Tuner, the tuner seems to keep resetting the sensors.

This is the graph when I just put my finger on the button and hold.

But my project setting didn't enable Sensor Auto-Reset in the CapSense

Setup:

CapSense V5.20

CapSense Tuner V5.20

PSoC Creator  4.2 (4.2.0.641)

Using this code to send CapSense data through UART.

Did I set it up wrongly? Or is there a way to disable the auto reset in the CapSense Tuner?

Hi benny,

It seems not a CapSense sensor auto-reset feature.

I think this problem might come from CapSense IDAC auto-calibration function or CapSense start function call in FW side. Or IC(PSoC) reset condition (XRES, POR, etc.) in HW side.

To verify this problem, please attach the project file.

Thanks,

Brandon

Hi Szin,

Oh I always thought it was the auto-reset.

Now I notice the code has no watch dog reset inside the for loop.

This solves my problem right away, thanks for your help
