How Do I Identify which I2C Host Adapter is Connected to which Port using LabVIEW?

Question from the Customer:

 I have two Aardvark I2C/SPI Host Adapters connected to my PC that are used in parallel. I am using LabVIEW. How do I determine which Aardvark adapter is connected to which port? As shown below, the ports are not differentiated.  How can I get the port information per Aardvark adapter?

How Can I Accelerate Results when Using Rapid Triggers to Read I2C Data?

Question from the Customer:

In our characterization lab we are using an Aardvark I2C/SPI Host Adapter as one of our I2C adapters. I’m currently working on a development project where I need to repeatedly read I2C data  after a trigger via GPIO pin at a rate of 400kHz.

The current implementation uses the Aardvark API Software and USB communic...

What Is the Safest Way to Power a Target 1.8V Device without Using an External Power?

Question from the Customer:
I have the I2C Development Kit and I am trying to use Flash Center Software to program an I2C target device, Macronix MX25U6435F.   I checked the datasheet and found its power input is 1.8V.  I’m concerned the Aardvark I2C/SPI Host Adapter can only output 5V. According to the datasheet, this I2C device can withs...

What You Need to Know About the Switching Frequency and Duty Cycles when Communicating with QSPI Chips

Question from the Customer:

I’m looking into used your Promira Serial Platform as a QSPI master to communicate with our chip. Before I get started, I’d to know these capabilities with the Promira platform:

  1. Our preferred QSPI format is listed below.  Are dummy cycles required?
    • No instruction cycle
    • 2-cycle of address
    • No alt cycle
    • 4-cycle d...

What Are the Details of the Software Arguments when Reading I2C Data Using Aardvark API Software?

Question from the Customer:

I am running tests with the Aardvark I2C/SPI Host Adapter using the Aardvark API Software. I have a question about the API Master Write-Read command aa_i2c_write_read. I input eight values using Arg 8 (in_data) to an array, but when I display array[0] and [1] to different elements, they show the same value. Let’s s...

How Can I Integrate the Cheetah SPI Host Adapter in an Automated Test to Accurately Record the Results?

Question from the Customer:
I am developing a production line functional test that requires programming a part. The test software launches the programming software and then prompts the test operator to press a pass or fail button to confirm whether or not the part programmed correctly.

However, I have observed operators sometimes do not press t...

Which Mechanism and Tool Do I Need to Write to an SPI EEPROM?

Question from the Customer:

I am starting to use Promira Serial Platform with the Promira Software API I2C/SPI Active. The spi_eeprom command does not specify what data should be written - I need to send 0x1000 to register 0x50. There is a queue variable in the code that I believe needs to be filled. How do I access the queue?

Also, I want to c...

How Can I Use the Aardvark I2C/SPI Host Adapter to Verify the Communication Protocol with a Microcontroller?

Question from the Customer:

I could use some pointers on getting started with the Aardvark I2C/SPI Host Adapter. I’m implementing an I2C communication between two PCs, each PC connected to an Aardvark adapter.  The goal is to define and implement the communication protocol, and verify it with the Aardvark IC2/SPI Host Adapter. Here’s an ov...

What is the Best Software to Use with the Komodo CAN Solo Interface to Read Complete Data?

Question from the Customer:

I am using the Komodo CAN Solo Interface with Komodo GUI Software to run a CAN module from a Linux host system. I am sending data through the General CAN Mode.  My concern is when reviewing the data log 3 out of 8 bytes of data at the receiving end are masked.

For example, if I intend to send deadbeef55667788, the C...

How Can I Best Update the Aardvark Software API to Promira Software API When I Need to Maintain Specific IP Addresses?

Question from the Customer:

I recently purchased the Promira Serial Platform to replace the Aardvark I2C/SPI Host Adapter. I am trying to “hand over” the Aardvark Software API code to the Promira Software API I2C/SPI Active code.

aardvark-250  Promira Serial Platform

At first, I tried using the Promira Aardvark Wrapper Software API to update the Aardvark I2C/SPI Host ...
