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:

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

What is PMBus?

PMBus, or Power Management Bus, is two-wire interface that defines the management of power subsystems. This bus is an extension of the SMBus protocol, so PMBus and SMBus hold many similarities. In this article, we’ll provide a high-level overview of the background of PMBus, how PMBus operates, where it’s used, and ways to debug ...

How Can I Filter Data to Only Grab the Data that Is Delivered to a Specific Endpoint?

Question from the Customer:

I am using the Beagle USB 12 Protocol Analyzer with Beagle Software API (python) to grab data. My device outputs data very quickly through Endpoint 1. However, I only need the IN data that is output by Endpoint 3, which delivers far less data.

The API example I started with is written very well, but I hav...
