CAPSENSE™ & MagSense Forum Discussions
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?
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)?
・Sense clock frequency
・VDD(Design wide Resourceのsystem上)
Capsenseのdesign guideのManually tuning hardware parameters、Sense clock frequencyに下記記載がございます。
Equation 25 shows that it is best to use the maximum clock frequency to have a good gain; however, you
should ensure that the sensor capacitor fully charges and discharges as shown in Figure 39.
このthe sensor capacitor fully charges and dischargesはどのように確認を行えばよろしいでしょうか？
I 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?
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?

I want to use a PSoC 4 device to continuously measure the raw capacitance of a two terminal capacitive sensor. The examples I found seem to detect changes in capacitance beyond a certain threshold, rather than measuring and outputting the raw capacitance value across two terminals. How would I do this? Are there any examples to follow?
Who can I contact to get Cypress CapSense support?
None of the original links in the datasheets seem work and I can't find the information to get started.
Also, where is the roadmap?
We are Australia based.
We are trying to use serial debug data from CY8CMBR2044. In the datasheet, a 41-byte packet is specified, however the chip is sending 71-byte data packets. Where can we find the specification for 71-byte packets? A 71-byte packet example:
0D 0A 00 03 0D EC 0D A9 0D A1 00 00 00 01 02 01 01 01 01 BB 36 34 34 11 08 08 0D EC 0D A9 0D A1
