How Do I Accelerate LabVIEW Write and Read Timing for I2C Devices?

Question from the Customer:

I’m testing an LED Driver for a rear lamp project. The LED is a slave device. The master device is an Aardvark I2C/SPI Host Adapter. I started the tests using the Control Center Serial Software. The slave device responded correctly and the delay between writes and reads was very small, as expected....

How Can I Use LabVIEW to Automate Programming SPI EEPROMs?

Question from the Customer:

We purchased four Aardvark I2C/SPI Host Adapters for programming SPI EEPROMs (AT25160A series).  I’m having problems getting started – can you help me read and write data to an SPI EEPROM?  I’ve tried using the Control Center Serial Software and Flash Center Software, but so far, no luck getting...

How Can I Make the Aardvark I2C/SPI Host Adapter Provide Interrupts to Get My Devices out of IDLE State?

Question from the Customer:

I am analyzing a device that supports NVMe MI 1.1, which also supports five Control Primitives.

To see how my device sends and receives MI Commands through the Side Band (OOB),

I am using two Aardvark I2C/SPI Host Adapters: one as a Master; one as a Slave.

My challenge is I am trying to work with a device...

What Details are Needed in the Profile to Accurately Run Type-C Cable Tests?

Question from the Customer:

I am starting to use the Advanced Cable Tester v2. I find the signal integrity eye diagrams easy to understand. The diagrams make sense to me as they correlate with the scope measurements in the lab.

I am curious about the accuracy of the GND/Shield resistance measurements. For example, one cable design has...

How Can I Best Monitor Data and Phantom Power on the A2B Bus?

Question from the Customer:

I’m looking at the A2B Bus Monitor - Level 1 Application for an audio system.  I have some questions:

  • How many total channels are available? Our system has multiple channels per board.
  • How is the SigmaStudio® software used within the system?
  • Can we capture data in formats other than .WAV file?
  • Could I ...

What are the Guidelines for Testing Ground and Shield Resistance of USB Cables?

Question from the Customer:

I am using the new Advanced Cable Tester v2 to test our USB 3.2 Standard-A to Type-C cables and am running into some problems after creating a custom profile. So far, I have not been able to modify the setting for the ground resistance to fit the specification. Here is where the test report shows failure:...
