ESP8266 Is Alive!

Posted by: Dave Vandenbout in Blog Post 4 years, 8 months ago

In my last blog post, I listed a bunch of online resources for the low-cost ESP8266 Wifi module. Now I'll go over how I got the module up and running in my own lab. <<more...>>


ESP8266 Resources

Posted by: Dave Vandenbout in Blog Post 4 years, 8 months ago

I received two ESP8266 Wifi modules in the mail yesterday. They cost a grand total of $10 and promise to make wireless interconnectivity cheap and easy with a simple serial interface. These guys got connectivity to a run-of-the-mill Wifi router at 366 meters using only the ESP8266's PCB antenna, so the performance looks good. <<more...>>

Building the ZPUino

Posted by: Dave Vandenbout in Blog Post 4 years, 11 months ago

In my last post, I introduced Alvaro Lopes' ZPUino port for the XuLA2. As I pointed out, the bitstream file he provides only works on the XuLA2-LX9, so now I'll show you how to rebuild the ZPUino from source. <<more...>>


I've never bought an Arduino, but now I have 1,000 of them.

My confession: I've never owned an Arduino; I've never used an Arduino. There, I said it.

It's not that I dislike the Arduino. Some people disparage it as a "toy", but anything that helps you get your project done quicker is fine by me. I just haven't worked on anything that would benefit from it.

So it surprised me when I found out I actually had an Arduino. In fact, I had thousands of them! Let me explain. <<more...>>


Schematics? Really!?

Posted by: Dave Vandenbout in Blog Post 5 years ago

Hearing talk about using schematics for FPGA design makes me feel like I'm standing at the top of a steep hill next to a toddler on a trike with loose wheel nuts. Some advice may be in order, to wit:

Get the hell off that bike! ARE YOU CRAZY!

Here's some ancient history: We used schematics back in the '80s for FPGA designs. We stuck with them through the '90s as FPGAs kept getting bigger, designs kept getting more complicated, and hardware description language (HDL) synthesizers got better and cheaper (and free!). Eventually, schematics got clubbed like a baby seal. Nobody uses 'em for anything serious, now. <<more...>>
