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 wr...

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 pro...

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, w...

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 y...

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 ...

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?
