LabVIEW NTP client

[hfettig]

Hi,

I was wondering if anybody had written an implementation of an NTP (Network Time Protocol) client in LabVIEW.

I am trying to figure out the best way to synchronize the RTC on the Blackfin processor to the network time.

Naturally I could just send a request to my host PC and get the time from there but there will always be the delay involved.

From what I've read in the RFC for NTP this delay is taken into account.

Cheers,

Heiko

You have probably already seen it, but here goes anyway:

Its not NTP and Iam not sure if it will work with the DSP module, but it may be a start.

Thanks a lot. I had not seen this yet. This is exactly what I was looking for.

Note that this example does not do the network delay compensation that you said you're trying to avoid. It does pretty much the same thing as a request to your PC for the time, except it queries a more precise server much farther away.

Just a quick thought, have you considered using GPS to get your accurate time base?

I know it sounds like an overkill, but in terms of development time its probably pretty cheap.
