Corona Time

So with the Coronavirus, the markets have been seeing increased volatility, and all the high frequency traders are making a lot of money, or losing a lot of money… I scrolled through the list of repositories on the fpganow github org and found a relevant project that deals with the parsing of market data only … Read more

What Hardware Am I Using?

I received an email from a reader asking me what controller I am using, so I figure I would make a new post with this information: (All links open in a new tab) PXIe-8105 Embedded Controller https://www.ni.com/en-us/support/model.pxie-8105.html PXIe-1062Q https://www.ni.com/en-us/support/model.pxie-1062q.html PXIe-6592R https://www.ni.com/en-us/support/model.pxie-6592.html And a picture (why not?):  

More Details About TCP

So first off, I have merged my code to master, see it here: https://github.com/fpganow/MicroBlaze_lwIP And while I work on updating the README.md file, here are 2 slides for you to look at: So, if you have the appropriate NI hardware, you can clone down this repository and run 1 TCP and 1 UDP session to … Read more

TCP is Now Working as Well!

As I was traversing my mental decision tree using a depth-first search model of digger deeper and deeper in to the lwip TCP/IP source code, I thought to myself that I should go back up the decision tree and take a deeper look at the tcpdump output. It turns out I was setting the source … Read more

Milestone Reached! UDP end to end

What I have working right now: A UDP packet enters the FPGA via the 10 Gigabit PHY that is connected to the FPGA. The 10 Gigabit Ethernet MAC running on the FPGA consumes the Ethernet Frame and passes it in to a c++ application running inside the MicroBlaze Processor. The MicroBlaze Processor is running a … Read more

Install Xilinx Vivado Tools on Fedora 27

The National Instruments “LabVIEW 2018 FPGA Module Xilinx Compilation Tool for Vivado 2017.2 – Linux” is only officially supported on Red Hat Enterprise Linux and CentOS. CentOS is basically a clone of Red Hat Enterprise Linux, also known as RHEL. I like to joke and call it R-HELL. The reason is valid, Red Hat Enterprise … Read more

Update

So it appears to me that Monero/CryptoNote mining has gained a lot of popularity lately, and this has led many people to this website.  Let me note that LabVIEW FPGA is a proprietary tool that comes with a 30-day Evaluation.  After that, you have to spin up a new virtual machine and reinstall LabVIEW to … Read more

LabVIEW FPGA, MicroBlaze, and UART – Full Guide

Working from scratch, I created a LabVIEW FPGA project that imports a MicroBlaze design that communicates with LabVIEW via a UART, and has the ability to change the elf file in a much shorter time frame than before. I did this by adding the MicroBlaze to the project after it had been exported to Vivado, … Read more

I Need Uart

Before I go any further and start wiring up my code to use the lwIP on the embedded MicroBlaze, I will need some sort of better method of debugging.  All code that I have implemented that uses a MicroBlaze processor via the Xilinx tools makes use of the UART to send and receive standard input … Read more
