Data Center Software Series: Understanding the Bus Pane

The Data Center Software is Total Phase’s free bus monitoring software that is used in conjunction with the line of Beagle Protocol Analyzers, Komodo CAN Duo Interface, USB Power Delivery Analyzer, and Promira Serial Platform with the eSPI Analysis Application. This software provides an interface that is used to capture, monito...

How Do You View a Waveform and Interpret the Details of Captured Data from a Protocol Analyzer?

Question from the Customer:

I am using the  Beagle I2C/SPI Protocol Analyzer with a PKSA for probing a temperature sensor. I have two questions about viewing and interpreting the captured data.

Question 1 - Scope Capture

Here is a temperature reading and an ID read from the PKSA and the decoded results using the Beagle I2C/SPI...

Can I send an SPI response of more than 256 bytes with the Promira Serial Platform?

Question from the Customer:

Our Promira Serial Platform is configured as a slave and is connected to a processor which acts as the master. The master sends 3 bytes of data on the MOSI and later reads 3 bytes and multiple dummy data bytes. The slave must then respond with the 3 bytes and the multiple dummy data bytes. The total...

How Do I Batch API Commands for High-Speed SPI Devices?

Question from the Customer:

Can you help me use Cheetah Software API commands correctly? I am using the Cheetah SPI Host Adapter running SPI at 1 MHz. I am trying to repeatedly send the target device four bytes of data (4, 41, 0, 0), as shown in the command sequence below.

However, after adding two repeats to the queue and the fina...

Data Center Software Series: LiveFilter

The Data Center Software is Total Phase’s free bus monitoring software that is used in conjunction with our protocol analyzers and offers a variety of ways to monitor and debug data in real time. One of the most useful features of the Data Center Software is the LiveFilter feature, which allows users to refine large stre...

When Do I Need to Add Pullup Resistors to Improve I2C Bus Tolerance?

Question from the Customer:

For my setup, the internal pull-ups of the Aardvark I2C/SPI Host Adapter will be disabled and 2.2k pull-ups will be connected from the SCL and SDA lines to a 2.7V voltage source. Here is a diagram:

Diagram of 2.2k ohm resistors : SCK and SDA lines to 2.7V .

My question – will this setup work? I am working on a system where signal voltage levels could v...
