PSoC 4 CapSense Tuner - "There was an error writing data from the device "

[MbK]

Hello everyone, 

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

Is there any solution for this issue.

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

Hi @MbK ,

Can you please confirm if there's any other instance of tuner is opened?

Also, Can you please try programming again and open tuner from the same project:
Right Click on the Project > ModusToolbox > CapSense Tuner

Thanks

Kind Regards

Hi @MbK ,

I'd recommend you to import existing PSoC 4100S MAX CE and see if you're able to open CapSense tuner or not? If yes, then I believe there is some issue with the EZI2C. Can you compare your code with the CE's EZI2C implementation and see if you missed something there?

Also, I'd recommend you to go through https://community.infineon.com/t5/PSoC-4/PSoC-4-CapSense-Tuner-There-was-an-error-reading-data-from-... this thread.

On top of that, Please make sure you have configured the I2C lines correctly and The same SCB block is not being used anywhere else.

Hope this helps! Let me know if you have any other issues.

Thanks!
Kind regards
