CAPSENSE™ & MagSense Forum Discussions
I would like to make buttons that can detect a conductive object put on the overlay.
I was thinking about using the CY8CMBR3110 and self capacitance measurement but I don't know what configuration would be best as the object won't be connected to ground.
- Configuration 1 : Sensors with a fishbone pattern (Rx = capsense signal and Tx = ground) with hatched ground plane connected to Tx (but won't my parasitic capacitance be too high ?)
- Configuration 2 : Sensors with a fishbone pattern (Rx = capsense signal and Tx = ground) with hatched ground plane but clearance between Tx and ground plane
- Configuration 3 : Round sensors with hatched ground (normal button configuration if you want to detect touch event)
- Or something different ?
Also is it possible to use several buttons at the same time ?
Lastly, if we disabled the auto reset, how long the sensor can stay in the ON position ? Can we let an object on the sensor for several hours and the presence will still be recognized ?
Thanks in advance,

I am using a CY8CMBR3110 Capacitive Touch chip set. I am trying to trigger the buzzer using the host controller over I2C. I was planning to trigger a beep every second for an alarm function. I cannot see anything in the documentation that would enable me to do so. If there is no way to do this, might railing the sensitivity of the proximity sensor high and low to force a proximity event potentially work for this case?

We are facing problems with availability of CY8CMBR3108-LQXIT on the market. The current design construction was based on this chip. Are there any "similar" chip-products available in your portfolio which has better availability and after some redesign works can be utilized in cicuit ?
Thank you for support in advance !Show Less

At Snehix we are making a solution based on paper tablet, tablets with E-Ink EPD Screen, for usage in school. Our solution will help increase teachers productivity, student engagement and most importantly will save lot of trees from being cut to make paper. A demo of our product is here https://www.youtube.com/watch?v=MRjV_yRRQvk&t=5s .
We are designing our hardware based on imx7dsabre evaluation board. We are using CYTMA448 touch sensor which I understand is Generation 5 touchscreen. I could see the driver of generation 4 in the repository I downloaded. Please provide me the driver source for the gen 5 touch screen. Some more supporting documents, test code will be really helpful.
Thanks and Best Regards,
