Is there a reference or guide to building code for the on-chip microcontroller? There is little information in the LMS datasheet specifying it’s usage and I can’t seem to find any other material in the other manuals. Is there a users guide for this piece? I do recall seeing the Python VNA software (pyLMS7002M) loading a custom .hex file onto the chip, but nothing beyond that.
Furthermore, it looks like it’s only capable of interacting with the SPI port. Does this imply that it can’t access any of the actual samples beyond the configuration registers?
