Hello!
I'm trying to use project CapSense_Tuner_EZI2C02 on my CY8CKIT-062-BLE to tune the board's proximity sensor.
I've tried the following
- Add the proximity sensor to the project on CapSense's configuration on TopDesign.cysch;
- Set proximity sensor pin to P8.0;
- Build the project;
- Flash the board;
- Start CapSense Tuner by right clicking CapSense on TopDesign.cysch, and then clicking "Launch Tuner";
- On CapSense Tuner, configure I2C as following:
- I2C address: 8;
- Sub-address: 2-Bytes;
- 3.3 Volts;
- ON;
- I2C Speed: 400kHz.
- Hit "Connect".
However, I get the following error message: "Checksum mismatch for the data stored in the device and the data loaded to the Tuner (expected: 0xC3C2, obtained: 0xA7DC). Make sure the chip is programmed with the correct hex file and communication channel configuration is correct."
It is important to note that everything works perfectly when I don't change anything (proximity sensor not added).
Solved! Go to Solution.

I was able to to make it work by creating a new CapSense_Tuner_EZI2C project in a new workspace.
Apparently, something happened in the other project/workspace that prevented me from using the proximity sensor.

You can try to re-program the chip again, and check whether the error has disappear.
And what the I2C data rate in your tuner tool configure?
You can attached your project, I can try to test it.
