Over the past few days I’ve been working on a fun FPGA project: getting a sprite (my little ship) to move around the screen on a Nexys A7 board, complete with a starfield background, rotation, and even thruster sounds when…
Over the last few weeks I’ve been implementing a minimalist 8-bit SAP-1 (Simple As Possible) computer on an FPGA. This post captures the architecture, the SystemVerilog snippets that make it tick, the VGA output I just added, and the little…
Programming music directly into an FPGA can feel like a grind—especially if you’re hand-coding note tables and timing values. When working with the Digilent Nexys A7 (100 MHz), I wanted a more direct way to take melodies I’d written and…
I have been working with my FPGA boards to attempt to display a test pattern on a VGA monitor. For my experiments, I bought a small VGA monitor*. It has a VGA input, as well as a HDMI input, so…
In a previous post, I covered the wiring diagrams, finite state machines, and LED segment encoding for the MAX7219 display module wired up to the Mojo FPGA. In this post, I will cover the Lucid HDL code used to implement…
I recently ordered a few LED display modules based on the MAX7219 chip. When they arrived, I immediately began putting together projects to use them. The first project was to wire one up to my Raspberry Pi and use C…
