CAPSENSE™ & MagSense Forum Discussions
I want to use a two layers FPC to design a slide with CY8CMBR3106S.But I'm not sure if the soldermask(usually use PI material) will affect the sensitivity or not?Should I expose the slide segment pad?Show Less
Hi, I’m a beginner of dev-board CY8CKIT-149.
My goal is getting the capacitance value and displaying it in some way.
Could you tell me how to do it ?
Is there any dedicated software provided by Cypress, or do I have to build the firmware myself?
Thank you.Show Less
As I know, Smart Sense (Full auto Tune) can solve most of cap sense turning problem.
But I feel a little curious about Smart Sense (Manual Tune) now.
What's kind situation you will select Smart Sense (Manual Tune) ?!
It's hard for me to image SNR < 5, if I select Smart Sense (Full auto Tune) already.
Because I feel Smart Sense (Full auto Tune) will always get SNR > 5. Auto-tune should be smarter than manual tune.
Base on above,,,
Could you please give me some actual examples that SNR can't reach 5 even I select Smart Sense (Full auto Tune) ?!
I would like to learn how do estimate what case I should use Smart Sense (Full auto Tune) and what case maybe I need to use Smart Sense (Manual Tune).
Thank you so much.Show Less
We released a board that uses the CY8C4147AZI-S475 controller to measure capacitance readings from 5 sensors. We look at the actual count value for our application and a problem has come up when we started to produce more boards. basically certain boards read far lower count values for certain sensors than others when reading the same capacitance. So far we've only seen cases where one or two sensors out of the five are reading lower. For example, a "good" board will read 960 counts, and if I apply the same capacitance to the "bad" board will give me 580 counts.
Any ideas on why it would be so inconsistent? Could it be manufacturing issues or something like that? I wouldn't think the PSOC controller itself would have that kind of variation chip to chip.Show Less
I use different demo kit and import following project to "design creator 4.4".
1. KIT: CY8CKIT-042, import project : CapSense_CSD_P4_Design,
I found the name of capsense block is called "CapSense CSD v2.6" (Attached file 2)
2. KIT: CY8CKIT-041, import project : CapSense_CSD_P4_One_Button,
In this project I can' find capsense block "CapSense CSD v2.6" (Attached file 1)
But I get a new capsense block which is called "CapSense v7.0"
I found the setting inside the "CapSense CSD v2.6" and "CapSense v7.0" are very different.
I feel a little confuse why different kit has different CapSense block ?!
Does different types of PSoC has different version of CapSense block ?!
How can I know which version of PSoC and its corresponding CapSense block ?!
Thank you so much.
We try use the EZ-Click V2.0 for CY8CMBR3102-SX1L, after click Apply current config the file cannot apply in it. please kindly check the attached file.
After study capsense "Tuner" software, I have a conclusion in the following...
No matter we select ...
1. Smart sense (Full auto turning)
2. Smart sense (Hardware parameters only)
3. Manual turning
The final purpose of above turning method is to make SNR > 5.
If SNR > 5 , this means this button is a good button basically. It's a basic ok threshold value.
If SNR < 5, please re-turn. this means this button must have a bad behavior in real application case.
For the turning software point of view, SNR > 5 is our final purpose.
If SNR > 5 is our final purpose, to select Smart sense (Full auto turning) will be the easiest way.
Is my concept above correct ?! If anything I lost, could you please kindly remind me ?!
Besides, if SNR > 5 is the best way, why manual turning still exists ?!
What kinds of situation manual turning must be used ?!
Thank you so much.
CY8CMBR3xxx Registers has three registers.
Configuration Registers: 0x00-0x7E
Command Registers: 0x80-0x87
Status Registers: 0x88-0xFB
What range is included in the Hex file generated by EZ-Click?
For example, what if the user wants to generate a Hex file with the value written to 0x92: DEVICE_REV?

I just want to know what i can measure. I dont understand the evaluation from the count/graph . Which unit is displayed? How i can get the code of ez click ?
Here the rise of a Button is shown! But wich unit was measured? Is it pF? or what concretely?
Please help me , thanks.
I'm learning cap sense by using CY8CKIT-044 kit. First, I found my SNR test is failed so I would like to re-tune figure capacitance according to user manual. But I can't find figure capacitance item in my tuner software. (Please refer to the attached file 1.)
Could anyone know why ?
Besides, when I found SNR test fail, to adjust figure capacitance to a smaller value is the effective way to let SNR test pass ?!
Do you have any guidance for me to know how to let SNR test pass ?!
Thank you so much.Show Less
