I2C error in 6.9.14

Postby VincenzoV » Thu Sep 11, 2014 8:30 pm

I have updated software for 3205A to Picoscope R 6.9.14.
Now I can't decode I2C, data seem random... I have attached an image with the latest relese and an old one.
I2C bus is working fine.

Hi VincenzoV,

Could you please post a PicoScope 6 psdata file here or e-mail it to support@picotech.com

There have been some recent fixes for I2C decoding which will be due out in a PicoScope 6 Beta release soon. This will enable us to check the data here.

Thanks,
Hitesh

Hi Vincenzo,

Thank you for the file.

I have passed it on to the Development Team via our Bug reporting system for further investigation. Please use the older version of the PicoScope 6 for now.

If you do have the data file corresponding to the screenshots on Windows, please e-mail it to support@picotech.com

Regards,

Hi Vincenzo,

Just a quick update - a new version of PicoScope 6.10 Beta is due for release soon.

In the Advanced Decoder Settings dialog, please try setting the value of Threshold 2 for both channels to 2V.
