Learn FGPA

I think the best way to understand something is to try and build something interesting with it. This is a repository of hardware projects using FPGAs.

Project Index

This is a summary of projects you will find in this repository.

ULX3S based on Lattice ECP5

These projects use the ULX3S board from Radiona labs:

https://github.com/mkvenkit/learn_fpga/tree/main/ecp5_ulx3s

Latice iCE40HX1k

These projects use the Lattice iCE40HX1k and the icestorm open source FPGA toolchain.

  • led_chaser - a "hello world" for FPGA
  • led_breathe - LEDs and PWM

Latice iCE40UP5k

These projects use the Lattice iCE40HX1k and the icestorm open source FPGA toolchain.

  • ultrasonic - talking to ultrasonic sensor HC-SR04 and displaying distance on a 4-digit 7-segment display

  • picosoc_gpio - simpe RISC-V based Picosoc demo that shows how to enable interrupts.

  • spram_test - demonstrates SPRAM block usage by displaying colour bars on VGA.

Migen Examples

  • blinky - a simple blinky in Migen/Python

Xilinx Zynq

These projects use the Xilinx Zynq SoCs which combine FPGA (PL) with ARM cores (PS).

  • blinky - this project (video, text, no source) shows you how to create a blinky on the PL of Xilinx XC7Z007S using the clock from the PS, using Vivado 2018.3.

  • simple_vga - a simple VGA project with a red grid and a yellow moving square.

  • video_ip_test - using Xilinx video IPs to show test patterns via VGA.

  • thermal_vga - displaying thermal sensor data via VGA
