Hi Konstanti, the most common reason for that is actually a typo in the file name or in the path; can you verifying the file is actually readable (i.e. ls -l /home/rfnoc/rfnoc_tutorial/share/uhd/imagesusrp_e310_fpga_RFNOC_sg3.bit displays read privileges)?

Hello Said, Unfortunately, no. Updated firmware requires the new hardware. Why are you not using hardware flow control? Which platform and application are you using? Regards, Abdul Hello Abdul, is there a way to upgrade older boards with a new microcontroller? I have a version 3.11 board, and can replace the micro myself. Presently I am bypassing the Hardware flow control using delays in the control software, not very elegant and it is quite slow. Thanks, Said

Hi Said, In that case the new firmware will not be compatible at all. The new hardware uses FTDI FT245R USB FIFO chip which has a parallel interface to the micro. Host side USB drivers make it appear like a virtual serial port, which is why all the serial port parameters can be ignored.

Hi Abdul, we modified the board to have true RS-232 output to talk to an instrument that just has RS-232, and we are bypassing the USB chip, but our RS-232 does not have flow control. This works well (with the timing loops) but I think with the new software it could be sped-up quite a bit. bye, Said ************************************** See what's free at http://www.aol.com. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts

The HP6626A Power Supply is my present instance. The Prologix GPIB-USB has the "++auto" command which controls if it should automatically go into listen after a talk, the description on the manual page is: Enable (1) or disable (0) "listen-after-talk" feature Based on that description, one would, or at least I would, expect the behaviour to be that nothing happens until the next write, so that this would work: ++auto 0 idle bus write something device= listen send data idle bus ++auto 1 idle bus write something device= listen send data device= talk read something But that is not the case. "++auto 1" puts the device in talk mode immediately, so the sequence needs to be: ++auto 0 idle bus write something device= listen send data idle bus write something device= listen send data idle bus ++auto 1 device= talk read something You've been warned :-) -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts -- No virus found in this incoming message.

The latest version of Prologix GPIB-USB controller firmware (v4.65) available at http://prologix.biz/update.html allows binary data transmission. CR (ASCII 13) and LF (ASCII 10) may be escaped by preceding them with the ESC (ASCII 27) character. -----Original Message----- From: time-nuts-bounces@febo.com [mailto:time-nuts-bounces@febo.com] On Behalf Of John Miles Sent: Sunday, July 01, 2007 10:04 AM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] HP5370B and GPIB I've got a basic data-logging example that works with NI and Prologix adapters (see 5370b.cpp in www.ke5fx.com/gpib/setup.exe ). There is one caveat on the Prologix boards that might apply to the Softmark adapter as well, though: you can't use the SB command to specify an arbitrary sample size in binary, because the board might interpret any ASCII 10 or 13 (LF or CR) characters as command terminators. The sample-size logic in my case looks like this (below). That's the only hangup I can think of, offhand. It doesn't sound like that's your problem, but it's worth noting once you get the basic communication up and running. Also, I don't remember if the 5370B asserts EOI at the end of each reading, so you might make sure you've configured the Softmark board to terminate incoming reads when ASCII 10 (LF) is received. -- john, KE5FX -----snip from 5370b.cpp----- // // Tell counter how many samples to take for each returned reading, after // forcing it to wrap up any measurement in progress by taking a single sample // // If sample size is not a power of 10, we must compose an SB // (Sample Binary) command string to specify the number of // samples we want the counter to take for each reading // // Prologix users will not be able to use this feature, since arbitrary binary // strings cannot be transmitted! // GPIB_write("SS1"); Sleep(100); U8 sample_string[16]; U32 n = (S32) (log10((DOUBLE) n_samples) + 0.5); if (n_samples == (U32) (pow(10.0, (S32) n) + 0.5)) { sprintf((C8 *) sample_string,"SS%d",n); GPIB_write((C8 *) sample_string); } else { if (GPIB_serial_configuration() != NULL) { printf("WARNING: Binary command transmission requires National Instruments interface\n"); printf("Measurement may not work -- use a power of 10 from 1-100000 inclusive\n\n"); } sample_string[0] = 'S'; sample_string[1] = 'B'; sample_string[2] = (U8) (n_samples / 65536); sample_string[3] = (U8) ((n_samples - ((n_samples / 65536) * 65536)) / 256); sample_string[4] = (U8) (n_samples % 256); GPIB_write_BIN(sample_string, 5); } -----end------ > -----Original Message----- > From: time-nuts-bounces@febo.com [mailto:time-nuts-bounces@febo.com]On > Behalf Of Brian Kirby > Sent: Sunday, July 01, 2007 9:25 AM > To: Time Nuts > Subject: [time-nuts] HP5370B and GPIB > > > ); SAEximRunCond expanded to false > Errors-To: time-nuts-bounces+jmiles=pop.net+jmiles=pop.net@febo.com > > If you are using a HP5370B time interval counter and logging data from > the HPIB bus, can I inquire to what you are using for an interface to > the HPIB bus and what do you log the data with ? > > I am basically trying to capture 1 second data from the 5370B using a > Softmark USB/GPIB card - and I am not having any luck at all. > > I see some effects of commanding, the display on the 5370 changes or I > get and error message - but I cannot read any sort of data back thru the > HPIB port. > > I would appreciate it if one could send an example of what commands I > need to send to set the port up and retreive the data. > > Brian N4FMN > > _______________________________________________ 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.

Hello, The long promised user manual is now available at http://prologix.biz/manual2 FAQ has been revised as well. Thanks, Abdul

Hello John, Prologix GPIB-USB controller provides a (virtual) serial port for communicating with instruments. In Python, you would use one of the serial libraries such as pySerial. I will email you a sample program. Mac Intel drivers are available for Mac OS X 10.4 (Tiger) and later. See http://www.ftdichip.com/Drivers/VCP.htm Thanks for your interest. Please email if you have any questions.

Hello Chuck, It appears that 3478A sends data continuously as soon as it is addressed to talk. Since the Prologix adapter is busy processing GPIB data it is unable to respond to USB commands. One solution is to turn read-after-write off (++auto 0) before connecting the adapter to 3478A, and then use ++read command to read one measurement at a time. Please see the manual (www.prologix.biz) for ++read command options. The other option is to set 3478A to one-reading-per-trigger mode using "T3" device command. See HP3478 manual (pages 39, 59). Then use the ++trg command to trigger the device. ++auto must be set to 1 in this case.

Hi Gang! I just bought a Prologix GPIB <-> USB converter model, version 5.00, and I am having some problems. It works fine on some of my instruments, but it just locks up when I hook it to an HP3478A DVM. The DVM is known good, and works great with my HP85B (doesn't everything?). Basically, if I do any commands that require bus activity, the Prologix locks up and refuses to respond to even the ++ver command. When I unplug the HP3478A, the Prologix once again finds its happy spot, and responds normally. Any ideas? -Chuck Harris _______________________________________________ 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.
