PSoC 4 MCU

Hi!

I am now using PSoC4 4100S Prototyping Kit and trying to figure out on how slider works.

It's a bit technical though.

1. How does the slider decide its position?

I know it is related to the difference between each sensor's raw counts but I need a further and detailed explanation.

Here I show the graph I took from CapSense Tuner.

I set the maximum position of slider to 200 and took graph while slowly slide my finger from SLD0 to SLD5.

2. On CapSense Tuner, what is the difference between Asynchronized and Synchronized in Communication mode?

Thank you very much,

Afif

Hi Afif,

1) The slider design section 7.4.3 of https://www.cypress.com/file/46081/download provides details regarding the centroid algorithm provided by the CapSense component.

You could refer to that.

2) Please refer to Graph Setup Pane -> Communication mode of CapSense component datasheet for information on synchronized and asynchronized mode.

(CapSense V6.0 - pg 129 of https://www.cypress.com/file/442046/download)

Thanks,
