How to capture continuous data streams using the Beagle I2C/SPI Protocol Analyzer

Question from the Customer:

I’m using the Beagle I2C/SPI Protocol Analyzer and need to save long message logs for analysis, a minimum of 24 hours. The buffer receives 12.5MB of data per minute. To log 24 hours nonstop, I would be storing 22.5GB of previous data in volatile RAM.  I would prefer to store the data logs on internal hard drive or...

How can I change SPI modes between sample and setup phases?

Question from the Customer:
I’m working with an SPI device where I need to change modes between sample and setup. I’m using the Aardvark I2C/SPI Host Adapter. How do I change the clock polarity (CPOL) and clock phase and CPHA?

Response from Technical Support:

Thanks for your question! You can easily change the clock polarity with the Contro...

Is it possible to multi-task the Aardvark I2C/SPI Host Adapter as multiple I2C slaves with separate slave addresses?

Question from the Customer:

I will be using my Aardvark I2C/SPI Host Adapter as an I2C slave to send a response to the request sent from the Master.  My question is can I use my Aardvark adapter as multiple I2C Slaves with different slave addresses? Some requirements:

  • I need to send my slave data to master every 0.25 Seconds.
  • My bus speed is ...

How do I set up the Komodo CAN Solo Interface to send or receive RTR frames with a device on the CAN bus?

Question from the Customer:

Can we use the Komodo CAN Solo Interface to send Remote Transmission Request (RTR) to another CAN device?  My colleagues have been trying with a CAN interface on their processor connected to the Komodo interface, but so far, there has been no response. How can we set it up so it works

There are Two Ways for a Beagle USB Protocol Analyzer to Export Data to WireShark - See What Works Best for You

Question from the Customer:

In the past, I have had great success using the Beagle USB 480 Protocol Analyzer with Data Center Software to collect Ethernet Frames over a USB 2.0 link. Now I am starting a new project where I’m adding Wireshark to the mix. How can I export the data captured in Data Center to Wireshark? Wireshark uses packet capt...

When monitoring data on the USB bus, how do I tell which data is from the host computer and which is from the device under test?

Question from the Customer:
I’m using the Beagle USB 480 Power Protocol Analyzer - Standard Edition to monitor data between devices and the host computer. Looking at the data transactions in the block view of the Data Center Software, I see “IN” and “OUT” transaction types – does that tell me the direction of the data flow?

How do I adjust the timing between slave select and the first clock for SPI frames?

Question from the Customer:

I am using the Promira Serial Platform to communicate on my SPI bus. I want to send SPI frames at 10 MHz and I would like to play with the time between the slave select (SS) line and the first clock (CLK) slope. For example, I want to send the same SPI frame with various SS to CLK times.

Is that possible? How would I...
