Support Question of the Week: How do I use the Beagle Protocol Analyzers as a Single Data Logger for Multiple I2C buses?

I am trying to find a data logger solution that is capable of logging multiple I2C buses in parallel. The buses are separate; they are not eight slaves on a single I2C bus. Of course, we will need to store the data from all eight I2C buses to a single drive. Which product(s) do you recommend?

Thanks for your question! For your logging application...

Support Question of the Week: How does the Aardvark I2C/SPI Host Adapter indicate ACK and NACK in I2C mode?

I am using the Aardvark^TM I2C/SPI Host Adapter. I am trying to understand the symbols in a captured trace:

Support Question of the Week: Which Software Tools Work Best with the Beagle USB Protocol Analyzer for Analyzing Raw Data Packets?

Q: I am troubleshooting a microcontroller USB host device, which is supposed to check two endpoints one at a time, one after the other. I am analyzing the data with the Beagle^TM USB 12 Protocol Analyzer.

The IN-NAK records shown by the Data Center^TM Software are collapsed as follows:

100 IN-NAK for the first endpoint
176000 IN-NAK for the secon...

Support Question of the Week: Which is the Right Host Adapter for In-Circuit Programming of SPI Flash Memory with (or without) GPIO?

I am starting a new project that will use SPI flash memory. Which is the better choice for in-circuit programming, the Aardvark^TM I2C/SPI Host Adapter or the Cheetah^TM SPI Host Adapter? I used the Aardvark adapter previously for the I2C bus, but not for in-circuit programming.

Also, do you have a document that describes the hardware setup for SP...

Support Question of the Week: What Software Should I use with the Cheetah SPI Host Adapter Software to Program Large Files to SPI Flash Memory?

Q: How can I use the Cheetah GUI Software with the Cheetah^TM SPI Host Adapter to program a SPI Flash memory with a large file? I have large FPGA image files to load to different addresses within the SPI Flash memory.

Thanks for your question! For your programming need, we recommend using the Flash Center^TM Software, which is the most suitable ...

Support Question of the Week: Using the Cheetah SPI Host Adapter Software to Insert Delays in SPI Traffic

Q: We are developing a system to log SPI data transfers with an embedded system. We are using the Cheetah^TM SPI Host Adapter to generate SPI traffic. So far, it works with single data transfers. The system requirements:

The length of each data package is 128 bytes.
We need a 0.1 millisecond pause before sending the next package.
During the p...
