LA5034 to analyze I2C bus

Kha · Post time 2017-8-22 03:21:16

The hardware of the logic analyzer is working. But the software version 4.0.1.10 is not working correctly.
In particular, when analyzing (decoding) the I2C bus, only the first byte is correctly decoded. The remaining bytes are decoded incorrectly.
This can be seen in the video: https://yadi.sk/i/pyP-ohwa3MByEH

Thanks for the link.
I installed a new version (4.0.2.1), but with her this problem remained.

In the photo you will see the old version (4.0.2.1), but with the new version (4.0.2.1) it also does not work.

Hello, Amy!
Have you tested the progamma on the I2C bus? Do you confirm incorrect work?
When will your company correct the error?

Hello, Amy!
I checked the operation of the LA5034 analyzer on the I2C bus. Now it works correctly. Thank you!
The start state and stop state are well distinguished on the oscillogram.
But it would be desirable, that bits W / R (write / read) and A / NAC (acknowledge / not acknowledge) also somehow stood out. For example, each with its own letter, and also with a different color.
