I am using the Beagle USB 480 Protocol Analyzer. Normally I have no problem, but I don’t understand the readings with this setup, which includes a 7-port USB hub as shown below.

I am designing a system that will use 12 Aardvark I2C/SPI Host Adapters. Are there any specifications or limits of how many Aardvark adapters to utilize in one system?

One of my favorite Christmas traditions is reading 'Twas the night before Christmas on Christmas Eve.  I look forward to hearing the melodic verses and envisioning the heartwarming story play out in my mind. Like Christmas carols that stick in your head, Twas the night before Christmas starts playing in my head shortly after Thanksgiving.

We have been using the Cheetah SPI Host Adapter with the Flash Center Software to program a Flash device in a Flash SOIC-8 Socket Board. The Flash SPI device has 3.3V voltage level signals.  As we now have 1.8V devices to work with, we are considering the Level Shifter Board (TP240610) so that 1.8V devices can be programmed in the socket. Is this the best solution, or are there other devices that could be easier to use for working with various SPI Flash devices that have 3.3V and 1.8V logical voltage level signals?

It’s an exciting time to be at the forefront of technology. For the USB world, the new USB Type-C connector and Power Delivery protocol sparked great interest and created a lot of energy at the recent USB-IF Plug Fest and Developer Days in Taipei, Taiwan. I was lucky enough to represent Total Phase with our CEO Gil Ben-Dov at both events. During the week of the USB-IF Plug Fest, the Total Phase testing suite had non-stop activities – the room was filled with people who are working with the newest power delivery specs from 8am to 6pm everyday. It was fascinating to learn about the newest USB technology and see how Total Phase’s USB Power Delivery Analyzer provides insights into people’s USB projects.

I am planning to buy your Beagle I2C/SPI Protocol Analyzer. In the Beagle Protocol Analyzer User Manual, the input high voltage signal level is noted as 3.3V with +/-10% tolerance. However, on the target board, the high signal level is limited to +2.7V (the MCU is powered with 2.7V). How can the Beagle I2C/SPI Protocol Analyzer accept +2.7V voltage signals as high logic level signals?

I have been using the Aardvark I2C/SPI Host Adapter for many projects. Right now, I have a new project where I’ll be using the Aardvark adapter in SPI master mode. As I understand it, the slowest clock rate I can use in master mode is 125 kHz. However, for this project, I need a much slower bitrate, about 50 kHz. Is where a way I can slow down the Aardvark adapter (or another adapter) to communicate with slower SPI devices?

“The USB Type-C Connector: USB will never be the same”, Embedded Computing Design (Sept 17, 2015), written by Dr. Jerry Krasner, Ph. D., Vice President of Embedded Market Forecasters, tells us about the rapidly growing development and implementation of the Type-C USB connector (USB-C).
