I have just spotted something wrong.
although the process I detailed before allows the dso to save a waveform, it is not necessarily saving it into the files that I thought it was. In fact i cant find where in the sd card it is saving at all.
Regardless of which file I try to open, I get the last saved waveform. Looking at the files on the sd card the only one with any info in it at all appears to be called _disk_ID.pod
I think we need a bit of guidance from the Seeed team on how this is supposed to work…
