gEDA-user: pcb: new footprints for minidin[3-8] and DIN
Hello list, i just wrote some PCB-footprint-files for horizontal-pluged minidin[3-8] and DIN-connectors, I hope they are usefull and dont contain too much errors. www.kbdbabel.org/pcb/ Is there a chance to get those included in the official PCB-distribution?

Re: gEDA-user: Iverilog synthesis problems
Hello Stephen On 25/03/08, Stephen Williams wrote: The -tfpga code generator for virtex is almost certainly trying to implement your gates with LUT2 devices. It uses an INIT= attribute attached to the LUT2 to specify the logic. That's pretty basic and should work. Looks like ngdbuild is not OK with LUT2 devices on spartan chips? That is weird. What exactly is the software that comes with that devel board? Can you use a recent Webpack instead? Futher investigation reveals that this is the problem, I found what I think is the component library used for the Spartan, and there is a text file with it that seems to be a list of primitives. There are no entries for LUT of any type, the closest I could find were fmap/hmap (mapping onto parts of the CLB?) and ROM16x1. There are however a very large number of logic gate entries, AND2, AND2B1, AND2B2.. AND3 (up to 9 inputs IIRC) along with OR, NAND XOR etc.. So I editied the EDF file and changed the LUT2 entry to AND2 - ngdbuild was quite happy with that. I even managed to add in OR2 and get the result I was trying to from my original program. The library I found seems to be the same for XC4000, spartan and spartan XL - I suspect Xilinx changed it for the spartan II - hence why most of their later tools won't work with it. The question is could I get a copy of the spartanII.lib file and use that and still PR the result?

Re: gEDA-user: 3D Falcon feedback mouse?
Steve Meier wrote: Looks like it might be good for use as the robotic arm of a pick and place machine. That's exactly what I was thinking! I recently outfitted an old XY pen plotter to work with a little vacuum pump as a pick and place machine for 0603 parts. It did work pretty well, but it's only got like 3/8 inch clearance. But it did save me from having to place about 2200 0603 resistors and caps by hand, on about 20 boards. (I'd be glad to share my code, but honestly it's sort of kludged together, mostly perl. It reads the Daumst and Zevantech pick and place files, and produced HPGL commands as well as toggled the bits on the printer port to control the automotive 12v vacuum solenoids(2) which controlled the suction and the lift functions. The source components were cut-tape and just double-stick taped down to the plotter surface, with the cellophane peeled off, so it could just pick them up as it needed them. A usb camera serves as an enlightenment aid.) I'm still looking for a good quality but small USB camera (low-res black and white or high-res color prefered) that works with Linux, that is not ov511 based, if anyone knows of such a thing. (The ov511 works great, but has a bug which causes the auto light gain control to get stuck with the brightness turned all the way up.) Also, does PCB produce any sort of pick and place files?

Gerbv has the ability to read Gerbers (natch), drill, and various pick-and-place files. I'd be interested to get a couple of your pick-place files just to read into gerbv to see if they are properly parsed and processed. That is, if your files aren't proprietary. Shoot me an e-mail off list if that's OK with you: sdb (AT) cloud9 (DOT) net. Also, does PCB produce any sort of pick and place files? Yes it does.

Re: gEDA-user: 3D Falcon feedback mouse?
True, and I actually do have a good old bt848 card that I got years ago! But anyway, I use a laptop for controlling this thing, and I guess I always assumed that a pcmcia bt848 card would be sort of spendy, and besides, having the camera ADC right on the same board or chip as the CCD/CMOS image sensor, then being able to grab frames directly over the USB is so nice. And besides, if I use an NTSC composite camera and a capture card, then I'll be dealing with interlaced video, which means that the odd field is 1/60th of a second before or after the even field, which means if there is any motion, I'll get interlace artifacts, which aren't good for machine vision. So I really like the idea of a usb camera solution. THanks, though! -Jesse andrewm wrote: Jesse Gordon wrote: I'm still looking for a good quality but small USB camera (low-res black and white or high-res color prefered) that works with Linux, that is not ov511 based, if anyone knows of such a thing.
