Use I2C interface on either the Click or Syzygy connectors

rknollman

I would like to use the I2C interface available on either the Click or Syzygy connectors.

I have followed the Xilinx Embedded Design tutorial available at https://github.com/Xilinx/Embedded-Design-Tutorials/tree/master/docs/Introduction/ZynqMPSoC-EDT  (particularly  "3-system-configuration.rst") to create the basic hardware config.  I selected the Avnet ZUBoard.   I then followed the tutorial "4-build-sw-for-ps-subsystems.rst" to build the "Helloworld" software project as a STANDALONE application.

I assume the I2C interfaces available on the Click or Syzygy connectors must be supported by PL logic.

My questions are:

       - Is the I2C logic to support the interfaces on the Click and Syzygy connectors already included in the ZUBoard support added when I selected the ZUBoard in Vivado when creating the system?

       - Where can I find example software source code (for use as with a STANDALONE software project) to utilize these I2C interfaces in the PL?

Thanks in advance

    Hi  :

       I don't have ZUBoard. However, I am in the middle of reviewing Pathway, Xilinx Embedded Design tutorial, recently. I might be able to find time this week to run I2C standalone application on my Zynq MPSoC platform. If you find answers before my experiment is done, it will be great. 

    Here is my answers for yours after I checked ZUBoard Doc from Avnet:

           - Is the I2C logic to support the interfaces on the Click and Syzygy connectors already included in the ZUBoard support added when I selected the ZUBoard in Vivado when creating the system?

      Answer: I think Click and Syzygy should work with I2C on ZUBoard. You need to populate I2C IP core either at PS configuration or add I2C IP core at PL. Using PS I2C IP would be easier as a start point.

     - Where can I find example software source code (for use as with a STANDALONE software project) to utilize these I2C interfaces in the PL?

    Answer: Xilinx IP driver does have examples for I2C:

    If you are not familiar with Vitis SW flow, I might need to create a blog for this topic this month.

    Good luck.
