A year ago we introduced the Pmod IP cores, IP blocks for easy drag and drop use in MicroBlaze designs. With ready to use IP cores, adding Pmods to your FPGA or Zynq board can go from hours of additional work down to minutes, especially if you are following our Using Pmod IP’s tutorial.
Since the time of introduction, more Pmods have been added and the tutorial has been updated to handle unique cases like using interrupts. The below tables are now included to help you stay up to date on which Pmods and system boards are currently supported, as well as help you navigate through some of the implementation details.
