My new Nano has options to save BMP, CSV, and other formats. The BMP works and looks like the screen, but of course resolution is limited. I hoped to get more detail from a CSV file. I was able to write one to the internal memory and view it on my computer.
The problem is that the file is just a single column of 4094 integer values ranging from 128 to 130.
I am looking at an I2C SCL signal, so there is a lot of time at 5V with brief drops to 0V in bursts. That is what I am trying to capture, and I can’t even tell if the CSV is related to the data.
Any suggestions? Maybe I’m making a beginner error, or maybe there’s a whole different approach I should be using.
By the way, the V3 I have does not have an SD slot as is often mentioned here. It stores to internal memory. Does that matter?
