CAPSENSE™ & MagSense Forum Discussions
Hello,
I'm working on a project were I need to measure or detect the waterlevel in an adjacent case where water is flowing. The intention is to create a pcb with a Capsense pattern and place is to wall of this case and use one of the Cypress MCU to do the algorithm. But I have no experience with this and don't know which MCU is best for this application.
We have a prototype that works with a STM32 MCU, but the accuracy is not good enough. That is why we want to switch to one of Cypress MCU.
My questions:
- Which Cypress MCU is best for my project?
- What kind of pattern for the Capsense sensor is best for my application?
If needed I can provide the Capsense sensor design pattern we use at the moment.
Thank you.
Kind regards,

I'm using Capsense. I want to tune my sensors. When I'm using smartsense then after touching the sensor I'm getting touch condition/switch on status for Capsense but when I go to manual tuning then in that case when I'm bringing my hand close to sensor and then touching it, Switch On status of capsense is not coming. Why is that? Why it's not happening in manual tuning but it is happening in smart tuning?
Show LessHi,
I'm using CapSense. I've implemented the EZI2C as well for sending CapSense data to CapSense tuner. After opening tuner When I touch my CapSense sensor it's showing very less rawcounts and Sometimes Rawcounts are not coming at all. Why it's happening? Can anyone please help me here?
Thank You for your help

I'm looking to use new capsense technology. Can I use it with kit-044? Can anyone please guide me about new capsense technology? How to use it psoc creator? I am not getting the option to change the technology.
thanks
Show LessHi Infineon Team,
I am using cy8mbr3108 capsense. I am using linux platform and using i2cdetect utility for detecting the touch sensor over I2C. I found that sometime it is able to detect the sensor and sometimes not. If I detect it too fast, then it is able to detect, otherwise not. I learned from datasheet that it is in deep sleep mode by default. It sends NACK before going it to ACTIVE state. So, need to perform address match again!! Any way of moving device out of deep sleep mode? How to avoid polling?
Another secondary question is , lets say the device is detected once and then going to write I2C register, at that time it might not be able to write as it will be in deep sleep right?

Show Lessit seems like I'll be getting an Infineon based TSDZ2.
Has anyone managed to use a J-Link to flash/program/configure the stock firmware to support 52V?
If so, how? Are there any resources I'm not aware of? I can't seem to find anything.
Any insight is massively appreciated.
Show LessHi all,
We are planning to use CY8CMBR3108 Capsense for our Linux product. I came to know that we can do the configurations from the modus tool. However, for communication with application I would need to have Linux driver which will communicate with Capsense and fetch the data. This driver then provide the data to user application. I looked into it , but I didn't found any Linux driver support. Can anyone help me with whether we have such linux driver for Capsense or not?

Show LessHello,
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

Show LessI want to tune the CapSense sensors, So for software parameters are there any prescribed values from where we need to start tuning or We have to select tuning parameters randomly(in a hit and trial manner) and then we have to further change those parameters to get the best result? Basically, How to start the tuning process of the sensor. Also please share some document to know the details about these paramters and what they signify?
Thanks
Show LessHi,
I wanted to make a sample project of CapSense and I got to know that we have to take care of the parasitic Capacitance value. I wanted to calculate the parasitic capacitance value of the sensor and I am using GetSensorCapacitance() function to print the value but PSoC creator is throwing undefined reference to GetSensorCapacitance error in PSoC Creator. Can you tell why it is happening? How to solve the error? Also, Is there a range of Parasitic Capacitance upto which CapSense can support?
