I have some trouble with understanding the following IC and its SSC interface:


It is stated in the datasheet, that the SSC interface is SPI compatible, exactly what I need. Now first of all, how should I connect this SSC interface to an SPI interface? Can I do it as follows:




DATA -> MOSI/MISO shorted together

Second, I'm not even sure if I can read out the absolute angular position of this sensor over the SSC interface alone, also I cannot find any list with all the available registers I can read/write to. I think this normally should be included in the datasheet. On the website of Infenion are no more datasheets available, that specifies this SSC registers. Anyone an Idea where this could be hidden?

  • \$\begingroup\$ You can find the register and protocol info in their user guide (sections 5 and 6). Note that the SPI interface is a bit tricky in that it's half-duplex. \$\endgroup\$

Register and SPI communication protocol details are in the User's Manual, not the datasheet.

  • \$\begingroup\$ Thank you very much. What's about the SPI to SSC connection, am I right with my assumption? Half duplex should be configurable for an STM32F410CBU6. \$\endgroup\$ Commented Oct 21, 2018 at 16:04
  • \$\begingroup\$ The connections look right to me. \$\endgroup\$
