The i2c serial decoding doest not seem to use the pre-trigger data, meaning if I try trigger on a falling SDA, the start condition isnt detected, even if the data is grabbed and showed on screen. Please ask the developers to include all captured data in serial decoding.

Now, I should elaborate why I didnt think 200ms/div would sample my signal. When I choose 100ms/div, the sample interval=163.8us, rate=6.104 kS/s and no.samples=6109, my signal looks like sawtooth indicating the samplerate is too low. When I select 200ms/div the samplingrate drastically increases (a...

Wow, I didnt realize the 200ms/div actually could grab at 1Msps. That solved my biggest problem
I will post some files with the decoder problems.

Thanks!

First, Im using: PicoScope® 6 - PC Oscilloscope software version: 6.6.13.15 Model: PicoScope 2204 Hardware Version: 16 Driver Version: 2.0.8.101 Im afraid that 200ms/div doesnt give me the samplerate I need to analyze my i2c stream. Ideally I'd like a lossless analyser that could grab data continuou...

There seems to be a bug in the serial (i2c) decoder tool. See the image: picoscope6.6.13.15-i2cdec-bug.PNG Note the start condition at ~430us. It is not grabbed, and reported as a byte write instead of a new read. (All thresholds are at 2.6v) I would also ask if you could add options to add start an...

Ive bought a 2204 to try out the i2c decoding feature and it gives me some headaces. 1. The sampling rate at 2ms/div is fine. At 5ms/div it gets too low. Is it possible to try a custom x axis at say 3 or 4ms/div? 2. The holdoff time is very large. Isnt it possible to get uninterrupted sampling at th...
