Not sure whether this has been discussed before: How does the scope handle SPI decoding (SCL, MISO, MOSI, CS) with just two inputs?
i would assume scl + miso (or mosi) + timeout
unless in the meantime they added the third digital channel
That might work, but they explicitly list all four signals, including chip select. If you want to use that in the decoding, it seems that you can't get away with just two channels.
And the manual (page 86 ff.) bluntly explains how to set up all four signals, one after the other. Does this section refer to a different scope?
Setup for SPI Signals
Setting the SPI (Serial Peripheral Interface) signal includes two steps: connecting the
CLK, MISO, MOSI and CS signals to oscilloscope; specifying the parameters of each
input signal.
