What is the Fastest Way I Can Switch from an I2C Master I2C to I2C Slave using the Aardvark I2C/SPI Host Adapter when Testing I2C Devices?

Question from the Customer:

I am using Aardvark I2C/SPI Host Adapter, and I’ve come to a stage in the project where I could use your help.  I’m testing SMBus/I2C devices running at 400 kbps. This test includes logging the following steps (which are repeated):

  1. As an I2C Master, I need the Aardvark adapter to transmit an I2C sequential writ...

Which Beagle USB Protocol Analyzer Should I Choose to Capture the Data of High Volume Transactions at an Airport?

Beagle 480 for high-speed transactions

 Question from the Customer:

My consulting firm just got a large contract. We’ll be testing and verifying a setup for high volume sales for airport stakeholders.  The system consists of a cash register, a tablet, and printer, and connectivity to the server farm. To better monitor transactions and provide real-time information, this project...

Can I Really Automate Jobs with My Aardvark I2C/SPI Host Adapter and XML Batch Scripts?

Question from the Customer:

I just started using the Aardvark I2C/SPI Host Adapter and I heard that batch scripting is supported. Can you show me examples of how to do this?  I’ll be working with I2C devices.

Response from Technical Support:

Thanks for your question! The Control Center Serial Software supports XML-based batch scripts, which...

What is the Easiest Way to Verify a Setup Before Testing SPI Devices?

Question from the Customer:

I have a new team running tests with the Aardvark I2C/SPI Host Adapter. I would like a way for them to easily verify the set up is correct before loading in our SPI devices and running extensive tests.  I’m looking for a really simple procedure.  What do you suggest?

Response from Technical Support:

Thanks for you...

How Do I Disable the Aardvark I2C/SPI Host Adapter Pull-Up Resistors when Testing a Specific I2C Flash Device?

Question from the Customer:

I’m using the Aardvark I2C/SPI Host Adapter to test an I2C Flash Device. Normally the low-current pull-up resistors built into the Aardvark adapter work just fine with my SPI and I2C chips, but this time it interferes with the I2C device I’m working on. Is there a way to disable the pull-ups on the SDA and SCL li...

How Do I Create New Test Profiles to Test Type-C Cables with the Advanced Cable Tester?

Question from the Customer:

I am new to the Advanced Cable Tester and have used some of the default profiles. I have some custom cables that I would also like to test. How can I set up profiles for these new cables?

Response from Technical Support:

Thanks for your question! Standard test profiles are for common, known cable types – these prof...

How Do I Monitor UART Data Over the RS232 Bus with a USB Protocol Analyzer?

Question from the Customer:
Our project is to monitor UART data for several hours. We want to integrate that feature in a software product. For that we need an API (C/C++). We have the Beagle USB 480 Protocol Analyzer – and would like to use it to monitor the RS232 bus and capture the UART data. Is there any way we can do that?

How Can SPI Devices Use Dummy Bytes for Reading Data of Nonstandard Word Lengths over an SPI Bus?

Question from the Customer:

I plan to use the Cheetah SPI Host Adapter to generate traffic on a 4-wire Mode 0 SPI bus at 8 MHz. The communication pattern is specialized. The protocol being used is not a full duplex. The master sends 3 bytes on the MOSI and then reads 3 returned bytes on the MISO. It looks like the Cheetah only returns the bytes ...
