I really don't know why you find basic I2C decoding difficult. ![Confused :-//](https://www.eevblog.com/forum/Smileys/default/confused0024.gif.pagespeed.ce.5xOqKkq0Co.gif)
New SDS2104X Plus.....didn't even set edge to falling and only added 2ms trigger Holdoff.
Select Decode and check it is set to I2C then assign channels and then adjust Thresholds.
It took longer to boot than make these decode settings....
So what am I doing wrong here in this picture? I'm trying to hack a DVD player's VFD display, and I'm looking at the I2C pins off the EEPROM, between the main IC, and the VFD MCU.
The Green trace is the SCL line, and blue is data. I didn't see any decoding happening, so I copied most of your settings, I'm on 10bit mode but I think I have the same trigger settings. It let's me choose which CH is SCL or SDA. I've tried serial triggering, and didn't get that to do much either. I've tired rising and falling edge triggers.
In 2 pic's I was triggering off SDA to get a better pic of SDA.
In the Utility settings, it still says I have 30 free uses of I2C left. So what am I missing here ? I've had I2C work on my sds1204X-E, I can try that too, I've had that work before.
But this is the 2nd time I tried I2C on the SDS2204Xplus, and not seem to get any thing. Do I have some other setting wrong or not activated ? All clues to me say that these really are the I2C pins, and not SPI, etc. I only have parts of the DVD player, so IDK what the IC is really sending, but it repeats, until it goes back to sleep or whatever.
