It's a great way to do scripting. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
[time-nuts] Prologix GPIB-ETH - Linux examples ?
I just got my Prologix GPIB-ETH I am 90% Linux Ubuntu based , and would like to get 99% based. So i am looking for some C code examples, implementing the linux networking part. I have sen the Prologix example C/C+ , but it's WINSOCK. I was thinking ... There must be someone out there using a Prologix GPIB- ETH with linux , that might want to share some code/lib. I saw a ref. for some Prologix stuff in the TimeLab source (win32 i think) , but i can't seem to find the source.

Look at this stuff: https://github.com/bsdphk/pylt As far as I know the GPIB-ETH is just like the GPIB-USB, except you open a socket in stead of as (usb-) serial port.

There's hardly any difference between Linux sockets and WINSOCK as far as that example code goes. Remove the WSAStartup/WSACleanup calls, change sprintf_s to sprintf, WSAGetLastError() to errno, SOCKET to int and you should be done. That's the easy part. The hard part is handling timeouts as the Prologix doesn't give any indication if a ++read timed out.

Re: [time-nuts] Prologix GPIB-ETH - Linux examples ?
Interesting, I've downloaded and taken a look at the example and noted how the Prologix doesn't use the Remote Procedure Call (RPC) method but a simple telnet-like connection. Follow Orin's directions to convert from WINSOCK to Linux-style socket calls. Maybe you should first take a look how to open a simple TCP connection under Linux and you'll find the system calls pointed out by Orin.

Re: [time-nuts] Prologix GPIB-ETH - Linux examples ?
I was thinking ... There must be someone out there using a Prologix GPIB- ETH with linux , that might want to share some code/lib. I saw a ref. for some Prologix stuff in the TimeLab source (win32 i think) , but i can't seem to find the source. Sorry, I should've been more specific -- when you run the (Windows) setup from http://www.miles.io/timelab/readme.htm it will give you a near-complete copy of my development directory at the time that version was built. By default, most of the program's .cpp/.h source code ends up in c:\program files\miles design\timelab alongside the 32-bit and 64-bit executables, and in various directories underneath it. This includes all of the data importers and TIC/frequency counter drivers, as well as the TSC 5115/5120/5125 drivers... basically everything is there but the TimePod driver source. For GPIB-LAN example code, you could look at the TCPBLOCK class in drivers\shared\comblock.cpp, as well as the module that abstracts the various GPIB providers (gpibport.cpp). . As Orin says the differences between Winsock and *nix/BSD sockets are not large, at least for trivial applications like this one. Higher-performance code will tend to use more OS-specific calls to set up overlapped I/O operations and such, but there's no need for that here. TCPBLOCK is a rather low-performance chunk of code, being structured to read one byte at a time. It's fine for GPIB work but you wouldn't want to write a browser with it. -- john ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
