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...
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:...
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:
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 ...
You have spent the last few years perfecting the craft of electrical engineering. Now is the time to finally put all of all your hard-earned knowledge to good. Let your knowledge shine at your first electrical engineering job interview. You already have all of the puzzle pieces that you need to nail the interview and now it’s time to put them ...
Leading the industry to improve data transactions with less power and lower cost, Intel is defining the eSPI standard, which many manufacturers – at the chip, board and system levels – are integrating in their products.
The eSPI (enhanced serial peripheral interface) is a serial bus that is based on SPI. The features include a four-wire inte...
Every person is faced with challenges and dilemmas, but the dilemmas engineers face are particularly daunting. The job of an engineer requires skill, grace, and careful navigation through social, scientific and political situations. Some of the most pressing life dilemmas engineers face involve the struggle between personal ethics and private go...
USB Type-C is still relatively new, but even as we get used to what it means for data and video use-cases, additional exciting new uses are being developed, such as USB Type-C as the main interface for headphones. Many industry leaders are touting the move from the 3.5mm jack to the USB Type-C port. It will be interesting to see how this move tu...
