Hello,

PSoC Creator component datasheet (PSoC4 CapSense) have been updated from v7.0 to 7.0a, 7.0b and 7.1.
However I can't find any difference in the Generated library code(.c and .h) and binary(.hex).

What is the difference between version 7.0 and 7.1?
Are there any functional differences?

MPN CY8C4025LQI-S411

- Using linear slider
- CSD-mode in use
- Detects finger position well but raw count values(vertical bars in widget view) are mirrored.
When finger is not present -> raw count are high values(bars are up).
when finger is present on slider -> raw counts values decreased and got to zero.

So it's kind of working. Finger position in slider work correctly. Raw count are inverted. Is there possible to invert raw count values? Any kind of help is appreciated

I designed a board with a CY8CMBR3002 version with only one button used in GPO mode ( no I2C)

We made 2 batches that worked perfectly.

On the third one , capacitive key does not work.

Nothing in design has been changed since first PCB.

We exchanged the suspected 3002 with an old version and defective board works again.

The issue was reported on the initialy working board.

Same with whole  boards where we could exchage this component.

So I think something has changed in this component.

Here are the markings :

* Works : CY8CMBR3002-SX 0197468

*Fails : CY8CMBR3002-SX 035715

We are stucked for deliveries with no solution.

Any idea ?

Hi~ 

I'd like to know whole booting sequence for the CYAT81658

But I've just found a sequence for XRES without VDDD and othres.

Please refer to the attahced image file

If you know the whole booting sequence waveform, please let me know

Thanks alot

I want to design a touch buttons that will work underwater, but the pcb size isn't too big. I'm thinking of using W1,W2,W3 buttons as protection pin, is that correct? How should I design the shield electrode?

Hello community,

currently we are developing a proximity button with the CY8CMBR3102-SX1I chip. But we have EMC problems with wired RF test (0,15-80mhz) and wireless RF test (10V/m 80-3000 mhz).  All of the software filters in EZ-Click are activated and the pcb is designed as in the design guide recommended. The circular antenna has a diameter of 30mm and a ground ring around it.

Has anyone experience with emc issues and the CAPSENSE technology?

best regards
