How to start CapSense tuning with CY8CKIT-149 kit

[Teijok]

Hello, 

I need some help how to start tuning with CY8CKIT-149 kit. I need to get demo working to put slider and buttons to glass overlay of 2mm thickness.

- Should i start with Auto-tuning or manual tuning? could you recommended documentation how to do tuning?

- Slider is placed to glass surface. Should i remove Acrylic overlay from slider(from dev kit)?

Best regards

Teijo

Hi,

[Ans]

First, the initial parameters are determined by auto-tuning.

See Section "5. CapSense Performance tuning".

[Ans]

After removing the slider overlay, you can either glue the glass overlay or assign the GPIO of CY8CKIT-149 to other pins and hardwire the original board.

What kind of development environment(IDE) are you planning to use?

If you are thinking of using "Modus Toolbox", I think the below URL and attached file will be helpful.

Because the CapSense of PSoC6 and PS and PSoC4 are almost the same.
