The Synergetic Advancement of USB-IF Specifications and the Promira Serial Platform for Cable Testing

Last week we wrapped up another USB-IF Compliance Workshop – “Plugfest” – in Portland. This was the 100th event, quite a huge milestone. The first event I attended was in the year 2000 or so in Milpitas, technology goals have certainly advanced since then!

Even compared to a year ago, the USB world is in a much different place. Type-C/Po...

I2C vs SPI Protocol Analyzers: Differences and Similarities

What do you choose for I2C and SPI protocol analyzers? Let's take a look at their differences and similarities.

About the I2C

I2C (Inter-Integrated Circuit) is an on-board communication protocol, which is ideal for short distances and low bandwidth. It has a master-slave architecture in which all slaves are connected to the master via two wires:...

How Do I Emulate Multiple I2C Slave Devices with a Single Aardvark I2C/SPI Host Adapter?

Question from the Customer:

I am using my Aardvark I2C/SPI Host Adapter as an I2C slave. Currently, I am able to set a single required response in the message window for a request from the Master.

Can I set up my Aardvark adapter to emulate multiple I2C slave devices each with separate slave addresses?  My setup is simple:

  • I need to send the ...

The Power of a Review in Electronics

As engineers, we all want the best product, but this often comes at a price. When you implement a new platform or device, there’s always a chance that it won’t work, that it won’t be quite what you expected, or, at the very least, that it just won’t do the job well enough. However, sometimes things can turn out worse than just a product ...
