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 AardvarkTM I2C/SPI Host Adapter.  I am trying to understand the symbols in a captured trace from the I2C Monitor :

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 BeagleTM USB 12 Protocol Analyzer.

The IN-NAK records shown by the Data CenterTM 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 AardvarkTM I2C/SPI Host Adapter or the CheetahTM 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 CheetahTM 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 CenterTM 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 CheetahTM 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...
