Hi Peter,
Thanks for quick response. Yes, guile-gnome0-dev is already installed in
my Ubuntu, so I think it should be some problem else. Any idea?
the related lines I can find in the configure file is below:
{ echo "$as_me:$LINENO: checking if (gnome-2) is available" >&5
echo $ECHO_N "checking if (gnome-2) is available... $ECHO_C" >&6; }
$GUILE -c "(use-modules (gnome-2)) (exit ((lambda () 0)))" > /dev/null
2>&1
ac_guile_module_required=$?
if test "$ac_guile_module_required" = "0" ; then
ac_guile_module_required=yes ; else ac_guile_module_required=no ; fi
{ echo "$as_me:$LINENO: result: $ac_guile_module_required" >&5
echo "${ECHO_T}$ac_guile_module_required" >&6; }
if test "$ac_guile_module_required" = "no" ; then
{ { echo "$as_me:$LINENO: error: required guile module not
found: (gnome-2)" >&5
echo "$as_me: error: required guile module not found: (gnome-2)" >&2;}
{ (exit 1); exit 1; }; }

Re: gEDA-user: Trouble with an usb oscilloscope
Hello Joerg, The analog front end is not built right now. I just feed the signal thorough some resistors into the analog input. In fact most of the components in the analog part have poorly calculated values. The analog circuit shall have a detailed review after the digital part will do that 12MHz sampling. I tried to measure the number of samples in a bit from a serial line but the length of a bit is not very stable. Anyway it seems that the number of samples correspond to about the same sampling frequency of 300KHz. The divider ideea is great ! My multimeter can measure up to 20KHz so with a divider I can easily reach 20MHz. Seems that I will go this way for now.

gEDA-user: PCB routing question
I auto routed a board and there were two rats that didn't get routed. I saw a path that would work so I drew a line from the pin to pin to connect the two pins and optimized and the rat went away. Is this fine to do? I then went through the net list and found all the nets were connected to what they should be. I didn't see anything in the manual about doing this but it seems like this is how it's supposed to work or at least be fudged into working. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Hang the input to your clock that you want to measure. Divide the output down so you get a few ten millivolts amplitude. Feed this into the sound card of your PC. Install a free FFT program and start it. If there is a 10MHz clock you'd get 10kHz out, if your clock is really only 300kHz your PC would show 300Hz. Now you have one of the cheapest frequency measuring tools possible because the PC is already there. -- Regards, Joerg http://www.analogconsultants.com/ ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

If the 4066, opamp input and traces tally up to, say, 50pF then this forms an RC lowpass that rolls off around 500kHz. Try 10K or less and see if things improve. > I do not have another oscilloscope around so I can only > guess that the sampling is very low by measuring average > voltage on the CLK inputs of the converter.

Re: gEDA-user: Trouble with an usb oscilloscope
Hello Eric, The ISP1581 has an 8 KB of FIFO. 6KB are allocated as a double buffer for isochronous transfer via DMA. The DMA circuit does the job of getting the data from outside, put it into RAM and validating it for transmission. The samples does not need to reach into the ATmega162 mcu RAM. What worries me is that the DMA may try to send something outside, creating a conflict with the A/D outputs (this DMA has a lot of other options specially for computer hard disk devices). This is my assumption for not getting enough speed. But until now no smoke.

Teodor, I have not used your particular chip but have done USB with Cypress's 8051 based controllers. Are your samples going to a RAM and then sent across the USB bus from there or are you sending the sampled data directly to the USB bus buffer?

gEDA-user: PCB to IGES converstion?
Hi all Another question for the group. Is anyone working on a tool or know how to import a pcb layout to an IGES file? Background I just did my second design with PCB. Works great! Kudos to you all! unfortunately for me, when we assembled the prototype, one of the components had a mechanical interference with the case. Grrr. With the new artwork we'd like to be able to import an IGES image of it into Solid Edge (a mechanical cad tool). Before I start down the path of writing my own tool, I want to be sure no one else has already started down this path. The minimum that I need it to do is: Parse the file for elements Look-up height information for elements from a separate file Convert the element description to the IGES format with the new height info Optionally take an outline layer and convert it to a board outline Somehow provide board thickness info So how about it. Anyone have this tool half built?

gEDA-user: Trouble with an usb oscilloscope
Hello everybody, I need some advice if there is somebody on this list and has experience with ISP1581 chip or DMA buses. Basically I made an usb based oscilloscope with the above mentioned usb 2.0 transceiver. This chip has a 16 bit wide DMA bus that I had connected directly with the outputs from the A/D converter. It is the DMA (master MDMA command 06) that drives the sampling. The maximum sampling speed should be about 12 Msps. From what I measured on the pc, it is only sampling at about 300Ksps. It is very frustrating: it is working, but not at the sampling speed the chip shall be capable of. Now I want to know if maybe I did something stupid and I have conflicts on that bus, or I just forgot a setting. I tried other timing settings there but the sampling rate is like a stone, always 300 Ksps. And even with the highest timings, there should be at least 2 Msps. I put the schematic here http://deep-blue.ro/tmp/main.pdf I do not have another oscilloscope around so I can only guess that the sampling is very low by measuring average voltage on the CLK inputs of the converter. And that is quite low about 0.5V when sampling is on, and 0V when off. The subject is off topic, but I can link it with gEDA because the hardware was made with gschem and pcb :) http://deep-blue.ro/tmp/o2.html Thanks, Teodor ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
