FPGA Graphics

Welcome to Exploring FPGA Graphics. In this series, we explore graphics at the hardware level and get a feel for the power of FPGAs. We’ll learn how displays work, race the beam with Pong, animate starfields and sprites, paint Michelangelo’s David, simulate life with bitmaps, draw lines and shapes, and finally render simple 3D models. Along the way, you’ll experience a Smörgåsbord of designs and techniques, from BRAM and finite state machines to crossing clock domains and translating C algorithms into Verilog. Read more

Hello Arty - Part 2

Welcome back to our three-part FPGA tutorial with SystemVerilog and the Digilent Arty A7. In part two, we’re going to learn about clocks and counting. Along the way, we’ll cover maintaining state with flip-flops, timing things with clock dividers, creating our first Verilog module, and controlling LEDs with pulse width modulation. You might be surprised how far counting takes you: by the end of this tutorial, you’ll be creating RGB lighting effects worthy of a cheesy gaming PC. Read more

Hello Arty - Part 1

This three-part tutorial provides a quick introduction to FPGA development with SystemVerilog and the Digilent Arty A7 board. No prior experience of FPGA development is required, but basic knowledge of programming concepts is assumed. If you can write a simple program in Arduino, Python, or JavaScript, then you shouldn’t have any trouble. I find working with FPGAs gives me a sense of delight so often lacking in modern software development. There’s something profoundly satisfying about designing at the hardware level, be it drawing graphics on a screen, producing sound from a speaker, or even implementing your own arcade game from scratch.
