Picoscope software cannot decode I2C data

Postby Darren.dgy » Thu Jun 25, 2015 3:19 am

Hi,
My PicoScope model is 5000 series, and I use the this scope to measure the I2C signal and decoding. The system host can receive the I2C data correctly, and scope can measure the I2C signal as well but cannot decode it. The attachment is I2C waveform. Why cannot decoding the I2C signal?

Hi Darren.dgy,

Have you tried the I2C decoding using the new PicoScope 6.11 Beta?

If not, please download it from:

https://www.picotech.com/downloads

This Serial Decoding feature has undergone some improvement work.

PicoScope software still cannot decode I2C data?
I am using PicoScope version 6.11.10.1540 installed 26. january this year.

Running on Windows 7 with new PicoScope 5444B, I2C vaveforms display nicely on channel A and D,
but I2C decoding give nothing.
Have used I2C decoding in earlier versions of PicoScope software,
Is there any trick workaround,
or how far back in earlier versions do I have to go?

Regards,
Mysil

Can you post a psdata file for the image in the original post, or something similar, just saving a single waveform buffer, it will keep the file size down, but has all the information needed. We can then load it here and check through all your settings. Alternatively send the file directly to support@picotech.com
