How Can I Get the Best Speed when Generating Signals with the Cheetah SPI Host Adapter?

Question from the Customer:

I plan to use the Cheetah SPI Host Adapter  and the Cheetah Software API (Python) for generating SPI signals to communicate with my board. Before I get started, can you tell me about timing delays from the API execution call to the signals generated at the Cheetah output?

For example, if I execute a SPI read API cal...

I Need to Program 129 Bytes to an I2C EEPROM, but the Host Adapter Stops After Programming 16 Bytes – What Do I Need to Change, and How?

Question from the Customer:

We purchased an Aardvark I2C/SPI Host Adapter for our product development and manufacturing evaluation. We ‘re trying to use this adapter with the Flash Center Software to program 129 bytes to an ST Micro M24C02-W I2C EEPROM.  Our problem - it consistently fails with a “Slave NACK” error.


Checking the SCL and...

How Can I Best Capture MDIO Bus Transactions with Total Phase Tools?

Question from the Customer:

Which Beagle USB Protocol Analyzer Should I Choose to Capture the Data of High Volume Transactions at an Airport?

Beagle 480 for high-speed transactions

 Question from the Customer:

My consulting firm just got a large contract. We’ll be testing and verifying a setup for high volume sales for airport stakeholders.  The system consists of a cash register, a tablet, and printer, and connectivity to the server farm. To better monitor transactions and provide real-time information, this project...

How can I send large data transactions, messages greater than 64 bytes, using the Aardvark I2C/SPI Host Adapter?

technology-serversQuestion from the Customer
For a communication scenario, I am using the Aardvark Software API for data transactions. Here is the call that I am using:

aa_i2c_write (handle, deviceAddress, AA_I”C_NO_FLAGS, numbytes, bufferin)

If I define numbytes=300, is there a limitation when sending data due to the buffer size of 64 bytes? In other words, I...

How Can I Obtain Details about Failures on my USB Type-C Cables Detected by the Advanced Cable Tester?

Question from the Customer:

I have the Advanced Cable Tester running tests on two identical working USB Type-C cables. The report shows one cable passed everything on the physical wiring section, but the other cable failed the physical wiring on SBU1 and SBU2. I have checked all wiring and function of these two cables to make sure they are wor...
