Microcontroller socket programming with CVIwindows

[SandeepRam]

Hello,

I am working on a project where a computer with CVIwindows GUI will be a server and my clients will be DS80C410 networked microcontrollers which has an inbuilt ethernet stack. The comm protocol will be TCP using socket programming. How do I develop socket programming on CVI to get the communication between microcontroller and CVI server?

Regards,

SR

Here is an article I've found about socket programming in CVI. I hope this can get you started. (Most relevant section of article is toward the bottom)

Hello James,

Thank you for your reply. I read the GetHostTCPSocketHandle() but not sure how will this work with our microcontroller. If you have any example code or any documentation it would help us a lot and I can purchase CVI for our development. Waiting for your reply.

Regards,

Sandeep.

I've attached an example c file for a multiclient TCP server from the shipping examples of CVI. CVI includes a TCP and a UDP library and you can add expanded functionality using the subroutine you mentioned. There's also some basic information on TCP programming in CVI in that document I linked in my first response.

Also you can get a 30 day trial of CVI here:

I hope this answers your questions.

Thanks James. I have understood the multiclient server example shipped with CVI. I will try to write the application and will let you know how that works out.
