Eye Diagram Basics and Embedded Systems

With each passing day, embedded system designs are becoming more complex as they require increasing data transfer rates, shorter cycle times, and other requirements.

Embedded systems engineers are required to sort out signal integrity issues quickly to speed up the development life cycle. You might already be aware that modern serial data links...

What is a Packet Sniffer?

The term packet sniffer might sound a little fishy and suspicious, but it isn’t anything like that. In network management, packet sniffing plays a very crucial role. Network managers and technicians use packet sniffers to diagnose underlying problems in their networks. So, a packet sniffer is essentially a tool that aids in monitoring network...

How Do I Sequence the Komodo CAN Duo Interface API Commands to Properly De-initialize a Device on the CAN Bus so that I Can Easily Re-initialize it Later?

Question from the Customer:

I have a Komodo CAN Duo Interface and I could use your help. I have a function that does de-initialization. I see km_close() returns 1 instead of KM_OK. Is this expected? What does the return value of 1 tell me?

Also, I’m trying to figure out what the proper sequence for de-initializing everything -- open, acquire, ...

Protocol Analyzers vs. Oscilloscopes vs. BERT Analyzers: Compare and Contrast

Features like interoperability and simple connectivity have led to the widespread use of USB protocol in embedded systems of almost all types. Despite the advantages, USB protocol in itself is quite complex. Quite naturally, detecting and isolating the source of a problem within the system might be a daunting task for an embedded systems enginee...

How Do I Use One CAN Interface to Communicate and Monitor Two Independent CAN Buses?

Question from the Customer:

I have one Komodo CAN Duo Interface. How do I use it to monitor two independent CAN buses?

Response from Technical Support:

Thanks for your question!  This is easy to do with the Komodo CAN Duo Interface.  You can use two instances of the Komodo GUI Software or the Data Center Software (or one of each) with channel ...

How compatible is the Aardvark I2C/SPI Host Adapter in SPI Mode with a Microwire device – can we program a Microwire EEPROM?

Question from the Customer:

I am working on a new product that uses a Cypress GX3 USB to Gigabit Ethernet and a Microwire EEPROM. The setup looks like this:

 Setup for Microwire EEPROM with Aardvark I2C/SPI Host Adapter

Can the Aardvark I2C/SPI Host Adapter program this EEPROM? DI and DO on the EEPROM are connected together (like a half-duplex SPI) - is that a problem?
