Thanks for the question! For your setup, you will need to con...

What is the Easiest Way to Program and Verify a New SPI Memory Chip in Duo-Quad SPI Modes?

Question from the Customer:

We’ve been using the Cheetah SPI Host Adapter, but working with a new SPI memory chip (GD25Q80CTIG) that supports Duo and Quad SPI modes, it looks like we need a different approach.

We have been creating XML files for new chips and prototypes – and like the UI of  your Flash Center Software. We would like to cont...

How and Why to use the API to Send a Stream of Continuous Data when the Promira Serial Platform is in SPI Slave Mode

Question from the Customer:

I have found it easy to use the Control Center Serial Software with the Promira Serial Platform but I seem to have a project that is more challenging. I need to send a stream of continuous data.

The configuration I am using:

  • The Promira platform in is SPI Slave mode
  • The Control Center Software MISO data is set fille...

Which Tool Should I Use to Have One SPI Master Control Multiple Chips on an SPI Bus?

Question from the Customer:

We plan to use a host adapter to exercise a target board that we are developing. This board has two chips on an SPI bus.  The setup includes a second board (that we are also developing) that will connect to the host adapter and pass the SPI to the target board.

We need a tool that supports two chip select lines for t...

With the Beagle USB 480 Protocol Analyzer, You Can Easily Create a Custom Class Decoder for a Captured Device

Question from the Customer:

I am integrating a proprietary device that uses a custom class to communicate with the host driver. For this project, I need a class decoder to interpret the packets received by the analyzer – what do you advise? I’m using the Beagle USB 480 Protocol Analyzer.

How Do I Emulate Multiple I2C Slave Devices with a Single Aardvark I2C/SPI Host Adapter?

Question from the Customer:

I am using my Aardvark I2C/SPI Host Adapter as an I2C slave. Currently, I am able to set a single required response in the message window for a request from the Master.

Can I set up my Aardvark adapter to emulate multiple I2C slave devices each with separate slave addresses?  My setup is simple:

  • I need to send the ...

How Can I Best Use the Aardvark I2C/SPI Host Adapter as an I2C Slave to Realistically Emulate Sensor Readings?

Question from the Customer:

I have an arm-based embedded controller that I use for thermal control when testing microprocessors. The controller communicates with multiple slave I2C temperature sensors including an I2C temperature sensor interface on our DUT (device under test). I would like to simulate this DUT interface with an Aardvark  I2C/S...

The GUI Software for the Komodo CAN Solo Interface Makes it Easy to Monitor Activity over the CAN Bus and Communicate to Devices

Question from the Customer:

I have been using the Komodo CAN Solo Interface with Data Center Software for monitoring the CAN bus.  Can I use the same software to send CAN messages and monitor the CAN bus, or is there another application that I should use for that?

Response from Technical Support:

Thanks for your question! You can use the Komo...

How Can I Best Deploy Multiple Queues with the Promira Serial Platform and SPI devices?

Question from the Customer:

I plan to use the Promira Serial Platform and the API Software with SPI devices. I’ll be sending commands and reading the responses. I have an application in mind, but before I get started, I want to be sure my application will work. Will you please let me know if I am on the right track?
