Personal Projects Advent Calendar 2018

Markus | Thursday, December 27th 2018, 00:00

-- 27 Days of Projects

Figure 1. Thank you for 2018!
2018 is coming to an end, and so it's time to tend to things that didn't get done over the year. For me, I've been wanting to talk about many of my old projects for quite a while now, but never got around to it.

So this December (or tbh, many were shot during November), I pulled together and made videos for 25 of my projects. They date from very recent (November 2018) back to my school days (2007), so there's quite some variation to the style and type of project. I hope that you will enjoy (at least some of) them.

Lattice MachXO2 Based FPGA Development Board

-- Tiny and cheap, but versatile

Figure 1. A rendered 3D-image of the Tiny-XO2 board

Introduction

The Tiny-XO2 is a small, versatile and cost-effective development platform for Lattice MachXO2 field-programmable gate arrays (FPGAs). It is built around a MachXO2-1200HC FPGA which features 1280 LUTs, 64 kbits of EBR SRAM and one PLL besides various other features[1]. The development board extends the functionality by providing a USB-to-serial converter and a crystal to allow quick and easy prototyping. All I/O pins are available on the .1 inch headers and labelled directly on the board. Figure 2 provides an overview of all the board's functions.

This video demonstrates a little program I wrote to emulate vcom/vsim using GHDL. It enables Sigasi to check syntax and to simulate using GHDL/GtkWave.
