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 c...

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...
