Very few know how Powerful this FPGA combination can be – Here is how to Control it

Monday, August 8th, 2016

Greetings inhabitants of the FPGA world! Today’s post is about a project that can be a huge part of a number of other different projects that use FPGA as their core. Be it a claw machine or a drone or a navigator robot, interfacing Joysticks with FPGA will be a fundamental part of many of your future work. This article will help you control any device on a two dimensional platform with the code for movement in the XY plane. Moving in 3D (flight in the case of drones) can be easily achieved by using two joysticks in place of one.

The Author has wrapped up her project in a set of 5 steps to keep things short and sweet. The hardware needed for this project is simply a FPGA board, a system with Xilinx Vivado installed, Digilent PmodJSTK and a USB A to B micro cable. A general idea regarding the project is given in Step 2. The Joystick uses the SPI interface to receive and transmit data from and to the FPGA board.

The code for this project has been readily supplied in step 3 as a zip file. The contents can be sorted into a number of modules which have been coded in Vivado 2015.4. So using a different version of the software will mean you need to copy paste the codes into a new project file in your system.

The code can then be converted to bit stream to programme the board. You can also programme 2 joysticks (for Drones or RC Cars) since only the top bank of the PMOD Header in the FPGA board (you may need to adapt this to your own board) has been used for 1 joystick.

Flying high with Zynq

Tuesday, December 22nd, 2015

Open source enthusiast? Drone enthusiast as well? FPGA fan? Rejoice! The first Unmanned Air Vehicule combining all those technologies has recently been announced. It’s powered by a Xilinx Zynq processor running ArduPilot, and its source code is planned to be released. The team behind the project used a DJI F550 airframe and plans to test on more hardware. One of team founders says that using the FPGA part of the Zynq allows an easier real time processing, especially computationally intensive tasks. Before we see a video of the flight, we’re happy to learn that the Zynq board runs on Linux!
