Can I Use and Identify Multiple Aardvark I2C/SPI Host Adapters when Reading and Writing to Multiple I2C and SPI Devices?

Question from the Customer:

I have some questions about using the Aardvark I2C/SPI Host Adapter. I am reading and writing to multiple I2C and SPI devices, and I need to control multiple Aardvark adapters. I am able to find multiple Aardvark adapters under the Windows Device Manager.  What’s the next step?

  • How can I use more than one Aardvark adapter at the same time?
  • Does each adapter have its own address that I can read?
  • So that I know which target device I'm reading, how can I identify which adapter I am looking at?

Note - for another project, I need to use four Aardvark adapters at the same time.

Response from Technical Support:

Thanks for your questions! The Control Center Serial Software can only connect to one Aardvark adapter at a time. If you want to use  the software to communicate with multiple Aardvark adapters, then you need to launch a separate Control Center Serial instance for each Aardvark adapter.

If you ware working with memory devices, you can use the Flash Center Software, With Flash Center, you can connect multiple devices to read and write in parallel; however, the slave devices must be identical. If the devices are different, then you need launch separate instances of Flash Center for each adapter, as in the example above.

Every Aardvark adapter has a unique serial number, which cannot be changed. You can use the serial number to identify your device. View the serial number in the Control Center Serial Software configuration window, as shown in the figure below.
