DAC8740H: Does the DAC874xH have an upper-layer PA SW stack?

Sean,

Are you asking about a HART software stack? TI does not have a HART stack to distribute. In the past, we have in the past worked with Smart Embedded Systems (https://www.smartembeddedsystems.com/) and they have developed a HART stack for the DAC874xH devices. They can be contracted for customer system solutions involving HART.

Sean,

I would contact them for more information about their capabilities and experience. I don't know of anyone in our group that has worked with this company, and it's possible that this is a partner with one of the microcontroller groups.

Sean,

If you're looking at a Profibus stack, you can check out this tool:

This should have some information about the stack for some EP devices. I've also sent you a response by email.
