What does I2C have to do with GPS data and how much more can GPS navigate on planet Earth?

satcomViewGPS data has been system integrated with UART for some time, an asynchronous system. With navigation becoming more prevalent in commercial products, as well as mobile robotic devices and the coming of self-driving vehicles, I2C is now being integrated with GPS signals.

These interfaces appear similar, both having two signal lines. Beyond that, t...

When is the Promira Serial Platform push-pull and when is it open collector?

Question from the Customer

I have some hardware questions about the Promira Serial Platform.  I am using two of the GPIO (pins 14 and 15) as DO (data output). Are they both open-collector pins?  Will I need to add pull-up resistors to my test board?

Response from Technical Support:

Thanks for your question!  The pins are dual function and ca...

How Embedded Systems have Transformed the Healthcare Industry With Biomedical Applications

Think about living in the 1950s. Color television was introduced. The auto industry was experimenting with their new concept of “the sports car.” And the medical industry was making its biggest strides to date. The antibiotic erythromycin was launched commercially by Eli Lilly; Jonas Salk announced his polio vaccine, the first open-heart sur...

Keeping Cool: Different Thermal Management Systems In Embedded Systems

While any computer is running, it creates thermal energy which heats up the system. When it comes to creating efficient computers and embedded systems, every engineer can explain the importance of ensuring that the devices operate at the correct temperature. When embedded systems become too hot, electrical signals may become corrupted, the hardw...

How flexible and accurate is the Advanced Cable Tester with polarity inversion for USB 3.1? Can I swap the differential signals and still continue the SS and SS+ eye tests?

Question from the Customer:

I have a question about using the Advanced Cable Tester.

Advanced Cable Tester

The USB 3.1 specification includes handling lane bit inversion. For example, the “+” and “-“ lines in a SuperSpeed or SuperSpeed+ differential pair can be swapped.

Can you confirm that the Advanced Cable Tester will properly execute the SS and S...

How Do I Control the Number Of Bytes For Single Bit Write and Dual Bit Write?

Question from the Customer:Question from the Customer:

I am using the Promira Serial Platform to communicate on my SPI bus.  I’m using the SPI Active - Level 2 Application. I need to perform an SPI dual bit mode write at 20MHz as a master. The specifications show I can do this – I’d like to find out more about the flexibility and program...

How do I 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...
