Hello, we use the example CE210291, but not for a button, but for a TouchPad (~ 25x25mm), 3x3 buttons. The buttons have a Diamond pattern. This on a 0.55mm glass back and front with Indium Thin Oxid (see attached image).
With the AutoTune setting, the Touch does not work well, no matter what sensitivity is set (some area are not detected correctly).

Is the design not correct, or does something need to be changed in the software setup?

Many thanks

I have a CY8CKIT-044 and would like to supply external power. It works when I apply power as shown on page 46 of the kit guide but it draws over 100 mA. I have tried applying the 5 volts to the Vin pin and Gnd without success.

What is the proper way to apply external power to this board?

Hello everyone, 

I am facing this issue with the CapSense tuner that I cannot seem to troubleshoot. 

I am using CYBLE-222005-EVAL  Connected to CY8CKIT-042-BLE Pioneer dev board and MiniProg 3

I have a simple capacitive sensor connected to the dev board. I am trying to use the Capsense Tuner to tune the sensor output

I am using the example from PSoC creator "PSoC4 CapSense Low Power-One Button"

Once I try to establish the connection to the tuner, I get this error "There was an error reading data from the device "

s

I added screenshots  below of the configuration parameters for both the Tuner and EZI2C

I would like to ask if someone faced this issue before, and how to resolve it,

Your help is very much appreciated. 

Thanks in advance 

Hello, 

I have noticed that 9 single capacitive keys require about half as much power compared to a touchpad with 3x rows, 3x columns and set to self capacitance. Is that correct?

Thanks

Hello there,

I'm trying to create an electrocardiogram on psoc 4, using a TCRT5000 Reflective Optical Sensor. But when I analyze the data in a graph, a strange thing appears, because I think that when I put my finger on the sensor, the signals should go up and when I take them out, the signals should decrease, but the opposite happens, as in the image:

Someone can help me?

My circuit:

Hi All,
