Re: gEDA-user: US Distributor for Balloon Board

I'm not terribly picky about the FPGA -- any reasonable Xilinx or Altera device should suffice. Does anybody on this list have any recommendations? What do you want to do? I am designing a lot of boards with an LPC2141 ARM7, Altera 3c25, USB client, RS232, SPI, uSD. No ram, no Linux, just the builtin flash and RAM of the ARM and FPGA, and 1MByte SPI flash. The frontend is fitted with a variable number of ADCs of various types. It is optimized for precision analog measurements. The FPGA and the ARM live on differnt ground planes, with LVDS-IO between, to isolate the noisy digital world (computer) from the frontend. This board is sandwiched between a power regulator board and a preamplifier board. The inputs to the preamps are usially quoted in pA or fC, that is just a few electrons. I don't think this is what you asked for, but, if that comes close to what you need, and are ready to do your board yourself, I will share my design to work from. Most work is in the software/firmware. I would prefer to buy from a gEDA supporter, and it will be logistically easier if I can purchase from someplace in the US. I cannot help with that. Thanks for any pointers. --wpd ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user -- Stephan Böttcher FAX: +49-431-85660 Extraterrestrische PhysikTel: +49-431-880-2508 I.f.Exp.u.Angew.Physik mailto:boettc...@physik.uni-kiel.de Leibnizstr. 11, 24118 Kiel, Germany ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

FWIW, the people behind Balloon (whilst using Altium for the core design), are very supportive of gEDA and the idea that designs around the Balloon platform should use open EDA tools where possible. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

Sure. I'll take the opportunity to update the latest libraries. Thanks, I appreciate that. Thanks also for all the effort you have put into the minipack build system and keeping the gEDA recipes, libraries etc. up to date - I really appreciate it. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: Please check for artaefacts in git HEAD PCB
Hi, Could people please keep an eye on PCB's git HEAD and report any rendering regressions... I've been shunting some patches and changes out of my pcb+gl branch in the hope of eventually being ready to push those changes. There have been a few clean-ups I've pushed today which should work, but are in quite complex (or nest-like) bits of code. These have not all necessarily come from the existing and tested pcb+gl branches. It looks like to keep the GL renderer happy whilst letting it live side by side with the existing GDK and XLib based renderers, I will have to poke at quite a lot of the core's code which assumes it can merrily issue drawing commands whenever it feels like it. This isn't going to be a quick process - so much for the idea I had yesterday that I'd be able to push the first bits of GL rendering code this weekend. The reason my pcb+gl branch works is that up until now it had the luxury of changing code in such a way which broke the other rendering models. To push it upstream it will have to learn to play nice. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

gEDA-user: Interpreter for automation schematics
Hi! I would like to use gschem to draw automation schematics according to Swedish standards. What I need is an interpreter that handles crossreferences, page numbering, BOM generation, and functions like finding duplicates. My question to you is how to best go about this. I made a test awk script to handle crossreferences. Example: I used a titleblock with numbers and letters for x-y coordinates. I made symbols for a Telemecanique contactor. 1 coil, 1 nc contact, 1 no contact, and the 3-pole contactblock. The coil had had the following visible attributes: name crossref1 - page and position of nc contact crossref2 - page and position of no contact crossref3 - page and position of contactblock The contacts had these: name crossref - page and position of the coil. The problem with this is that I only made use of the braces in the *.sch files, and looked for the attribute names in a certain depth. This was only a test and is not reliable. I want to use a real guile interpreter, but this is all greek to me at the moment. I would appreciate any advice on how to go about this. //John attachment: john.vcf ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
