i2c decoding high sample rates fails

Post by bennog » Fri Aug 23, 2019 8:42 am

I am working on an application that uses i2s at 3Mhz and i2c at 100kHz.
With normal settings the 3403D samples at 250MS/sec.

For the i2s decoding this is not a problem.
The i2c decoding fails on the decoding in this case.
The data send in all samples was exactly the same. 0x10 0x00 0x01

When reducing max samples per capture to a value of 100kS / capture (eg 41.6 MS/sec)
The i2c decoding starts working normaly.
