| 16:34.59 | halem | so anyone works with FPGA here? |
| 16:35.58 | halem | anyone worked on any sort of USB FPGA implementation where it talks to the Linux USB host? |
| 16:42.32 | halem | anyone here using a USB microscope under linux and could tip me off about good and compatible brands etc..? |
| 16:47.19 | sjhill | wow, i did not know there was such a thing |
| 16:47.35 | sjhill | halem: you mean a USB target device implemented in FPGA? |
| 16:47.40 | halem | yep |
| 16:51.57 | sjhill | Rule #1, Do not use anything from Synopsis |
| 16:52.21 | halem | synopsys? |
| 16:52.24 | halem | or synopsis? |
| 16:52.29 | halem | synopsys is a great company |
| 16:53.09 | sjhill | you're welcome to your opinion, but i do kernel and rtos for a living and their USB stuff sucks |
| 16:53.22 | halem | you're talking about synopsys? |
| 16:53.37 | sjhill | yes |
| 16:53.53 | halem | ok |
| 16:53.54 | halem | weird |
| 16:54.16 | halem | im using a usbee dx now for all |
| 16:56.06 | halem | sjhill: in my personal opinion i liked that board |
| 16:56.10 | halem | had a lot of connectors too |
| 16:56.11 | halem | :D |
| 16:57.44 | halem | sjhill: what do you think of the DE2 board? |
| 16:58.00 | sjhill | haven't used it |
| 16:58.03 | halem | ISP1362 |
| 16:58.04 | halem | ah ok |
| 16:58.17 | halem | which board have you worked with |
| 16:59.37 | halem | sjhill: was looking for a board that had a 2.0 host/slave chip something like the one from philips |
| 16:59.59 | halem | or tcp in vhdl |
| 17:00.00 | sjhill | just their fpga synthesizable core stuff, the boards i've dealt with are all custom designs |
| 17:00.10 | halem | ah ok |
| 17:00.38 | halem | fpt tcp in vhdls, dod they use a controller with builtin stack ? |
| 17:00.58 | sjhill | i've only worked with their USB stuff, nothing else |
| 17:01.06 | halem | no no im asking |
| 17:01.10 | halem | for boards that do tcp in VHDL |
| 17:01.18 | halem | are they usually controllers with builtin stacks? |
| 17:01.42 | sjhill | *shrug* dunno' |
| 17:02.06 | halem | have you worked on any big boards |
| 17:02.16 | sjhill | no |
| 17:02.24 | sjhill | all my stuff is deeply embedded |

| 19:55.48 | halem | just wondering |
| 19:55.58 | halem | nobody solders individual pins on a 100+ pin tqfp? |
| 19:56.17 | roxfan | maybe some people do |
| 19:58.04 | halem | but its not sensible you mean? |
| 19:58.28 | roxfan | there are better ways, yes |
| 19:58.29 | halem | FPGA is still expensive |
| 19:58.34 | halem | roxfan: such as? |
| 19:58.36 | halem | hotair? |
| 19:59.15 | halem | I think I got a 0.5mm pitch 200~ odd pin fpga soldered and board made for like.. $140 or something |
| 19:59.23 | halem | FPGA is still kinda expensive for a personal project |
| 19:59.27 | roxfan | for example http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=96 |
| 19:59.33 | roxfan | or reflow in an oven |
| 20:00.44 | gentooma | maybe you could also use those schmartboards? schmartboard.com |
| 20:02.11 | gentooma | http://schmartboard.com/index.asp?page=products_qfp -- costs about 10$ |
| 20:03.07 | halem | must be chinese |
| 20:03.08 | halem | :D |
| 20:03.34 | halem | we have a reflow oven at work |
| 20:03.39 | gentooma | I've tried them and they are really easy to solder |
| 20:04.05 | gentooma | (if you buy there let me get some referal money :P) |
| 20:04.28 | halem | http://schmartboard.com/index.asp?page=products_qfp&id=116 lols |
| 20:04.30 | halem | looks so cool |
| 20:04.30 | halem | :D |
| 20:05.02 | halem | gentooma: oh those are the ones with the grooves right? |
| 20:05.27 | halem | erm the best they can do is a 250x250px photo? erm |
| 20:05.33 | gentooma | okay soldering the 240 through holes aren't fun either :) - but I think the idea is neat |
| 20:05.55 | gentooma | yeah with the grooves |
| 20:06.03 | halem | http://www.flickr.com/photos/11213386@N04/4420449377/in/photostream/ better photo of a low pin count one |
| 20:07.00 | gentooma | hmm it seems like its the same photo as on their page :) |
| 20:07.01 | halem | gentooma: haha well you probley don't need all those holes |
| 20:07.02 | halem | ::P |
| 20:07.22 | halem | if you needed more then like 30 i/o's you'd want a custom board made up and stuff anyway |
| 20:07.31 | halem | thats the thing I realised right after buying a FPGA dev board and getting it to blink leds |
| 20:07.58 | halem | any project that requires a FPGA, basicly requires you make a custom PCB with all the hardware setup just to be able to start deving the firmware for the FPGA |
| 20:08.01 | halem | right? |
| 20:08.18 | gentooma | https://engineering.purdue.edu/ece477/Webs/F07-Grp05/nb/images/cpoluski/ECE477033.jpg |
| 20:08.32 | halem | I mean you can simulate shit on the PC side sure, but you can't properly simulate the interactions beween any of the hardware, you can do basic shit with stim files but even then its pertty hit or miss |
| 20:08.41 | halem | and trying to protoboard ram onto a FPGA? gotta be joking me |
| 20:08.45 | halem | right or wrong? |
| 20:11.03 | halem | and you stll have to make your final board, so you might as well just take a stab at making a workable board the first time |
| 20:13.13 | halem | http://www.rapidmicros.com/images/dlp-fpga.jpg |
| 20:13.26 | gentooma | unless you need only some peripherals or building a prototype with only few external hardware |
| 20:13.30 | halem | 'This module is the same hardware as the RM5000, but without the Interpretive BASIC firmware installed. The installed FPGA is a Xilinx Spartan-3E-250-VQ100' lols" |
| 20:13.31 | halem | lol |
| 20:13.45 | halem | what do you mean gentooma? |
| 20:15.58 | gentooma | I mean you don't have to use a custom pcb for prototyping |
| 20:19.11 | halem | ah |
| 20:19.11 | halem | ok |
| 20:20.09 | gentooma | but if you have the ressources (and someone who knows howto do it right) to build one from start thats great |
| 20:21.01 | halem | such as yourself |
| 20:21.01 | halem | :P |
| 20:33.53 | *** join/#elinux lyakh (~lyakh@213.28.64.93) |
| 20:35.32 | halem | gentooma you still have to build and connect those though |
| 20:35.33 | halem | :P |
| 20:35.48 | gentooma | yeah |
| 20:37.08 | halem | and typicaly if you needed a FPGA, your not dealing with slow buses, and want higher freqency operation.. requireing very short connections to achive without problems.. or termination resistors/etc |
| 20:37.17 | halem | Making connecting it all up an even bigger problem |
| 20:37.34 | halem | maybe with some really simpl FPGA projects it could be viable to prototype, but I just don't see it for the majority of projects that actualy needed a FPGA, and could'nt of been easily done on a PIC or AVR |
| 20:37.36 | halem | dont you think? |
| 20:39.10 | gentooma | I see your point - yeah |
