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...

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 ...
