AD9361 SPI configuration logging in IIO Oscilloscope

garethdickin on Jan 24, 2022

Is there a way to log the SPI writes to the 9361 from the IIO Oscope GUI? I see the debug tab can look at individual registers, I'm interested in setting up a full config and recording the entire sequence of SPI writes used to set the configuration.

Thanks!

Using AD9361 this way is not really supported since having a single set of registers can result in unstable configurations. Primarily from calibrations that are unique to temperature and device.

If you really…

No this is not possible with IIO-Scope.

What is your end goal here? Are you trying to go towards a fully fabric-only system (No micro)?

If you really want to do this, I would look at the No-OS driver. Logging of the AD9361 SPI interface is trivial to add.
