===== Peripherals =====

  * The USB104 A7 is compatible with [[zmod:start|Digilent Zmods]], as well as other modules that conform to Opal Kelly's [[https://syzygyfpga.io|SYZYGY Standard Specification]]. Example projects for the Zmod DAC and Zmod ADC can be found in the [[#example_projects|Example Projects]] section, below.

  * The USB104 A7 is compatible with modules that conform to Digilent's Pmod™ Specification, including Digilent's line of [[pmod:start|Pmods]]. Digilent provides IP cores and hierarchical blocks to support the use of many Digilent Pmods. Guides and documentation on the use of these systems can be found below.

    * Walks through installing Vivado and Vitis, the development environments used to create hardware and software applications targeting Digilent FPGA development boards.
  * [[programmable-logic:guides:getting-started-with-ipi]]
    * Walks through using Vivado and Vitis to create a design in hardware and software that uses a processor to control buttons and LEDs.
  * [[programmable-logic:guides:getting-started-with-vivado]]
    * Walks through using Vivado to create a simple design that blinks a single LED.
  * [[learn/programmable-logic/tutorials/pmod-ips/start]]
    * Digilent Pmod IPs can be used to control connected Pmods from baremetal software.
    * It should be noted that not all Pmods are supported and that Pmod IPs are only supported in versions of Vivado 2019.1 and older.
