The Nexys A7 board is a complete, ready-to-use digital circuit development platform based on the latest Artix-7™ Field Programmable Gate Array (FPGA) from Xilinx®. With its large, high-capacity FPGA, generous external memories, and collection of USB, Ethernet, and other ports, the Nexys A7 can host designs ranging from introductory combinational circuits to powerful embedded processors. Several built-in peripherals, including an accelerometer, temperature sensor, MEMs digital microphone, a speaker amplifier, and several I/O devices allow the Nexys A7 to be used for a wide range of designs without needing any other components.

- Walks through installing Vivado and Vitis, the development environments used to create hardware and software applications targeting Digilent FPGA development boards.
-
- Walks through using Vivado and Vitis to create a design in hardware and software that uses a processor to control buttons and LEDs.
-
- Walks through using Vivado to create a simple design that blinks a single LED.
-
- 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.
