MKR 4000 VIDOR Hands-On Video | AddOhms Live

Arduino MKR VIDOR 4000 Hands-On | AddOhms Live #11

As promised, the Arduino team shipped the MKR 4000 VIDOR by the end of July. The graphical editor is still missing in action, but you can check out the board now. I received mine. In this AddOhms Live Stream, I turned it on and checked it out.

This video is a “working” live stream. Generally, I try to set up some demos and run through some canned actions. Not this time. I used the board once, on another computer. You get to watch how I attack a new board…live! Warts and all.

Key things I check out:

  • How do you program the FPGA? (what does that even mean for the VIDOR.)
  • The VidorTestSketch (communicate between the SAMD21 and the Cyclone FPGA)
  • LogoDraw (the VIDOR draws the Arduino logo over HDMI)
  • The include files for each of the VIDOR libraries

I’m writing up my experience so far, along with what I’ve learned. Until then, click below to see the 1-hour live stream.

Standalone Arduino Turn-On and Debug

This AddOhms episode is part 3 of the “design your own Arduino” series. In this one I populate a bare PCB, reflow solder it, debug a few issues, and load the Uno bootloader. Originally, I designed 2 versions of the board. One version contained an error that I planned to fix in the episode. Well, turns out, the “correct” board had two issues which were more interesting.

Check out the #27 show notes for links to a bunch of stuff in the episode, including the design files.

Creating an AddOhms Animations – Behind The Scenes

Pretty often I am asked about how I create the AddOhms animations. Currently, I’m working on the final part of the DIY Arduino Series. In the first part, I showed the elements of an Arduino schematic. The second part showed an overview of the PCB design. Finally, I will take the finished board and explain how to turn it on the for the first time. Lucky for me, there was a “mistake” on the board. This error gives some context for the episode.

I needed to explain how the Arduino Uno’s (and Mega’s) “auto-reset” circuit works. I did a live stream showing how I created the animation sequence for this explanation. Well, I started to explain. After almost three hours of streaming, I was only about half-way through the one-minute explanation.

While long, I think the stream helps to illustrate the kind of work I put into my videos. Speaking of which, I need to get back to finishing this one.
