Question from the Customer:

We use several Cheetah SPI Host Adapters for programming in our production runs and the R&D department. We have been using Atmel AT45DD041D-SSU SPI serial data flash device in our designs. However, Atmel no longer manufactures this device, so we have to change our design. The SPI flash device that we chose is the Ade...

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...

Question from the Customer:

I need some help with programing and testing SPI chips on my board. I am using the Aardvark I2C/SPI Host Adapter with the 10-Pin Grabber Clip Split Cable. I am new with the these tools and have some questions:

• What is the purpose of the NC/+5V line on the cable?
• The signal levels of my SPI target devices are 2.5V. ...

Question from the Customer:

I am looking into purchasing the Aardvark I2C/SPI Host Adapter for computer communication with a microcontroller on an external board for data exchange. I am planning on using a Visual Basic platform to develop an easier customer interface to access the information.

• Can I use Visual Basic with the Aardvark adapter?
• A...

Question from the Customer:
I am using the Aardvark I2C/SPI Host Adapter. For this project, I would like to use Flash Center Software to program the IDT TSE2004GB2B0 I2C EEPROM, which is a 512 byte device that is configured in two 256 byte pages. I have tried to create an XML file to program this I2C device, but can’t figure out how to make i...

Question from the Customer:

I plan to use the Aardvark I2C/SPI Host Adapter with the external software application Agilent/Keysight VEE. I have installed the Windows driver but cannot detect the adapter in the VEE software. Are there dll libraries that I need to add in system directory or in the VEE installation directory? I see that Total Phas...

Question from the Customer:
I am using the Cheetah SPI Host Adapter to send large data blocks at maximum speed. I find that I'm getting reliable SPI transmission for long blocks at 40Mb/sec, which corresponds to 5MB/second - these results are OK.

However, the fastest I can queue data to send using ch_spi_queue_array, in blocks of less than 64KB...
