Using PXIe-6571 as a I2C SLAVE

[Sruk]

Hi,

I'm a new guy in this field of work, and there is much questions to ask, but let me start with a simple one. I saw an example of 6571 as an I2C MASTER so I was wandering if such a device could behave also as a bus SLAVE.

I'd like to test some parameters on a MCU bus MASTER via Digital Pattern Editor or LabView.

Please advise the possible work flow direction regarding the use of PXIe-6571.

Many thanks!

You can in fact implement an I2C slave using 6571 with some features limited to the flow control capabilities of 6571. Example, if you are waiting for a state on a pin, you can use MATCH opcode but those results are available exactly after 80 vector cycles, which in many cases you don't want.

Thank You Santhosh,

actually, I would need a pretty basic stuff from 6571 to process, such as: START/STOP condition recognition, ADDRESS ACK/NACK, a and 1 byte data SEND/RECEVE.

Where can I learn more about this 'opcode' stuff anyhow?

All the best!
