| 14:22.51 | prpplague | chouimat|work: morning |
| 14:25.13 | GPSFan | prpplague: been thinking about a wearher station app with a built in web cam. the other option is an NSLU2. (the software is currently running on a webpal as well as all sorts of other platforms including the NSLU2) That's about all, lots of farm stuff going on this week though. |
| 14:26.44 | prpplague | GPSFan: yea, the hammer would be great for that, i've been testing the webcam stuff |
| 14:26.56 | prpplague | GPSFan: there are a whole host of usb webcams that work |
| 14:27.24 | GPSFan | prpplague: ah, what have you got working? |
| 14:28.40 | prpplague | GPSFan: i've not had as much time to work on the hammer as i would like |
| 14:28.51 | prpplague | GPSFan: we've got two new products in the pipe |
| 14:28.56 | prpplague | GPSFan: based on the s3c2440 |
| 14:29.09 | prpplague | GPSFan: so i've been busy doing board support package stuff |
| 14:29.33 | prpplague | GPSFan: but i was able to find some time to test some webcam stuff yesterday for the purpose of using them in robotics |
| 14:29.46 | GPSFan | prpplague: ok, I've been looking at the spca50x driver. |
| 14:30.11 | prpplague | ahh |
| 14:30.33 | prpplague | GPSFan: the ones i have are syntec based |
| 14:32.44 | GPSFan | biggest problem is trying to coordinate what webcams are supported with what you can buy on-line and locally. I have a sn9c201 +ov7660 which works nicely on MacosX & winblows, but is not yet supported in linux, although work is being done on it. |
| 14:33.16 | prpplague | GPSFan: yea, i had the same problem, i purchase 6 different ones from geeks.com |
| 14:33.23 | prpplague | GPSFan: all but one worked |
| 14:33.38 | GPSFan | ah, what did you get that worked? |
| 14:34.33 | prpplague | http://www.geeks.com/details.asp?invtid=PC002&cat=VID |
| 14:34.39 | prpplague | that one is my favorite so far |
| 14:34.57 | prpplague | it's pretty small and i hacked to run on 3.3v instead of the +5v from the usb |
| 14:35.29 | chouimat|work | prpplague: nice |
| 14:36.56 | GPSFan | prpplague: cool, I got one of these; http://www.geeks.com/details.asp?invtid=1MP-988-WEBCAM&cat=VID but it is snc9201 based and it ain't 1.3M pixels. the sensor is an ov766o which is 640 x 480. |
| 14:37.32 | prpplague | GPSFan: oh, you are wanting a higher resolution that what i was testing for |
| 14:38.15 | GPSFan | well I'd really like 1024 x 768 but I'll take 640 x 480. |
| 14:38.36 | prpplague | GPSFan: ahh interesting |
| 14:38.47 | prpplague | GPSFan: probably should start a list on the wiki with ones we have tested |
| 14:39.10 | GPSFan | good idea. |
| 14:40.16 | prpplague | GPSFan: i've started a section for "i want to use the hammer with" |
| 14:40.20 | prpplague | GPSFan: on the main page |
| 14:40.33 | prpplague | GPSFan: we can add a "web cam" section |
| 14:46.34 | prpplague | GPSFan: ok, i got a rough page posted |
| 14:47.12 | GPSFan | prpplague: good, I'll add stuff to it as the project progresses. |

| 19:23.27 | Crofton | what do you mean? |
| 19:24.19 | prpplague | i'm confused as to what software is running on the pc that the usrp hardware plugs into |
| 19:25.24 | Crofton | ah |
| 19:25.31 | Crofton | gnuradio? |
| 19:25.36 | prpplague | Crofton: yea |
| 19:25.50 | Crofton | basically a signal processing package the uses the USRP for data collection/transmission |
| 19:25.59 | Crofton | you can also develop your own software |
| 19:26.05 | Crofton | which is what we do |
| 19:26.28 | prpplague | so you are using the usrp hardware? |
| 19:26.54 | Crofton | yes |
| 19:27.04 | Crofton | via the usrp librarry from gnu radio |
| 19:27.46 | prpplague | Crofton: ok, so the cypress chip is just using the default firmware, and then you are using custom apps on the pc side to tell the cypress chip what to do |
| 19:27.51 | prpplague | Crofton: that correct? |
| 19:27.56 | Crofton | yeah |
| 19:28.06 | Crofton | we use the firmware from gnu radio |
| 19:28.20 | Crofton | and a library from them to deal with the usb interfacing on the host side |
| 19:28.38 | prpplague | Crofton: gnuradio stuff isn't well documented, i'm struggle to understand the interfacing |
| 19:28.53 | Crofton | heh |
| 19:29.00 | prpplague | Crofton: which firmware are you uploading to the cypress chip? |
| 19:29.06 | Crofton | look in the usrp directory |
| 19:29.25 | prpplague | i am |
| 19:29.32 | prpplague | i see an "apps" directory |
| 19:29.35 | prpplague | with several apps, |
| 19:29.45 | prpplague | but i don't actually see the firmware that is uploaded |
| 19:29.48 | Crofton | http://gnuradio.org/trac/browser/gnuradio/trunk/usrp |

| 19:30.19 | prpplague | http://www.gnuradio.org/trac/browser/usrp2/trunk/firmware/apps |
| 19:30.25 | Crofton | firmware is the 8051 code |
| 19:30.43 | Crofton | fpga goes into the Altera part |
| 19:30.52 | Crofton | and host is the code built on the PC |
| 19:30.59 | prpplague | Crofton: right, i see those apps, but which one is the one you are using? |
| 19:31.04 | Crofton | libusrp |
| 19:31.53 | Crofton | I have my own piece of code that links against libusrp |
| 19:32.19 | Crofton | from http://gnuradio.org/trac/browser/gnuradio/trunk/usrp/host/lib/legacy |
| 19:34.09 | prpplague | Crofton: when the cypress is enumerated on the usb port, you have to upload some firmware to it, where is the firmware that you are using? |
| 19:34.42 | Crofton | libusrp deals with that |
| 19:35.01 | Crofton | the images are in usr/share or something like that |
| 19:35.34 | Crofton | ls /usr/local/share/usrp/rev4/ |

| 19:39.48 | prpplague | whats the difference between ursp and ursp2? |
| 19:39.58 | Crofton | do not look at usrp2 :) |
| 19:40.14 | Crofton | wait |
| 19:40.18 | Crofton | maybe you should |
| 19:40.51 | Crofton | there is a nomenclature issue |
| 19:40.59 | Crofton | usrp2 in this case is rev2 of the board |
| 19:41.19 | Crofton | in general it USRP2 is the next gen usrp, that uses gigE not USB .... |
| 19:41.40 | prpplague | ahh ok, thats what the problem was |
| 19:41.45 | prpplague | i was looking in the usrp2 dir |
| 19:42.21 | Crofton | the usrp2 directory is likely used |
| 19:42.32 | prpplague | Crofton: ok, so i can replace the the cypress chip with a hammer board |
| 19:43.00 | Crofton | they unload data from teh FPGA using the state machine in the FX2 |
| 19:43.01 | prpplague | Crofton: just not sure what to do after that, i see the functionality in the src for cypress, looks easy enough to replicate under linux |
| 19:43.25 | Crofton | this is a high performance data path from IO to usb buffers, not processed y 8051 |
| 19:44.04 | Crofton | to interface to the hammer, I would increase max decimation in FPGA to cut data rate |
| 19:44.16 | prpplague | Crofton: whys that? |
| 19:44.47 | Crofton | the slowest available data rate atm to 250K samples per sec, where a sample is 2 16 bit ints |
| 19:45.42 | prpplague | Crofton: but normally isn't that transmitted to over the usb interface to the host device? |
| 19:46.32 | Crofton | Tell me why you would connect the hammer to the FPGA? |
| 19:47.05 | Crofton | the 8051 in the FX2 does USB interface housekeeping and setup |
| 19:47.21 | prpplague | Crofton: i would assume to do the same thing you would you would normally connect the fx2 to a host pc |
| 19:47.21 | Crofton | the actuall data transfer paths are outside the 8051 |
| 19:47.43 | Crofton | so replace PC with hammer |
| 19:47.53 | prpplague | Crofton: basically cutting out the middle man of the fx2 |
| 19:48.00 | Crofton | the key here is the hammer is much lower perf than a PC |
| 19:48.18 | Crofton | the gnu radio guys are not focused on small processors |
| 19:48.30 | prpplague | Crofton: indeed it is around 100mips |
| 19:48.34 | Crofton | so, we need to make changes in the FPGA to help processor |
| 19:48.36 | Crofton | yeah |
| 19:48.52 | Crofton | the PC can swallow around 8 MHZ of spectrum |
| 19:49.00 | prpplague | Crofton: so once the packets are on the pc, what is done with them? |
| 19:49.07 | Crofton | this is running USB full speed |
| 19:49.12 | prpplague | Crofton: converted to semi-realtime audio? |
| 19:49.12 | Crofton | math :) |
| 19:49.27 | Crofton | audio is easy to do realtime |
| 19:49.42 | Crofton | someone had a HD tv decoder (that was non-realtime) |

| 19:51.57 | Crofton | but CRC used a RF front end to convert RF to audio frequency and digitized with the audio syste, |
| 19:52.09 | Crofton | the bw of that is enought to do NBFM |
| 19:52.15 | Crofton | 44ksps |
| 19:52.52 | Crofton | I need to talk to a guy here and see if he has something similar, expect using a SPI AD converter |
| 19:53.08 | prpplague | interesting |
| 19:53.21 | Crofton | or hack USRP FPGA to do SPI |
| 19:53.39 | prpplague | Crofton: the hammer does have two AD converters |
| 19:53.44 | Crofton | ah |
| 19:53.46 | Crofton | :) |
| 19:54.06 | Crofton | 100 ksps or so, I think I alrady checked |
| 19:54.43 | prpplague | Crofton: so basically you are converting the rf to a different freq, and then doing sampling |
| 19:54.47 | Crofton | let me see if hasan is about, I need to ask him some things |
| 19:54.49 | Crofton | exactly |
| 19:54.54 | prpplague | interesting |
| 19:55.11 | prpplague | Crofton: i'm pretty sure i can get you a hammer kit of you guys want to post some howtos |
| 19:55.20 | Crofton | it should be possible to make a hammer based FRS radio :) |

| 19:55.45 | Crofton | he does public safety research |
| 19:55.54 | prpplague | ahh ok |
| 19:55.56 | Crofton | those guys have all teh spectrum no one else wanted |
| 19:56.03 | prpplague | hehe |
| 19:56.27 | Crofton | so they use spectrum all over the place, makes quad band phones look like childs play :) |
| 19:57.07 | prpplague | hehe, aren't alot of the inexpensive walkie-talkies FRS? |
| 19:57.13 | Crofton | yeah |
| 19:57.22 | Crofton | of course they are not software defined radios either :) |
| 19:57.32 | Crofton | this is using a sledge hammer to opn nuts |
| 19:58.01 | Crofton | of course the sdr approach allows you to move beyond NBFM easily |
| 19:58.23 | prpplague | you lost me there |
| 19:58.52 | prpplague | Crofton: i was looking at basics for the hammer |
| 19:59.04 | prpplague | Crofton: you were thinking that you needed the sledge hammer? |
| 20:04.57 | chouimat|work | prpplague: I think I will wait for the JackHammer ;) |
| 20:06.50 | prpplague | chouimat|work: that will have like 1000 GPIO pins |
| 20:06.58 | cbrake | prpplague: does zcomax sell a SDIO adapter board for thier module? |
| 20:07.09 | prpplague | cbrake: yea |
| 20:07.22 | cbrake | prpplague: I don't see it on their site, so I guess I'll ask them |
| 20:07.26 | chouimat|work | prpplague: enough to take over the world |

| 20:36.48 | prpplague | jimp: the board is 10 layers and the license for which it will be release is still being reviewed |
| 20:37.00 | jimp | Great, thanks for the info |
| 20:37.05 | prpplague | jimp: probably be licensed under BOHL |
| 20:37.28 | prpplague | jimp: what kind of project are you looking to use the hammer with? |

| 21:28.32 | hapchap | prplague: i guess he did not like your suggestions? |
| 21:29.03 | prpplague | hapchap: nope, he's all concerned about going directly to formfactor |
| 21:29.43 | prpplague | hapchap: considering starting a betting pool to see when he actually hands chris a netlist |

| 22:30.05 | flyback | prpplague what the canuck |
| 22:30.16 | flyback | did you know that analog devices is still selling a parallel port sound codec |

| 22:30.25 | flyback | 16 bit 44 khz |
| 22:30.35 | flyback | and plcc package :P |
| 22:30.35 | prpplague | flyback: nope |
| 22:30.38 | prpplague | flyback: url? |
| 22:30.44 | flyback | ad1845? |
| 22:30.52 | flyback | it was on the ensoniq isa soundcard |
| 22:30.57 | flyback | hang on |
| 22:31.11 | flyback | http://www.analog.com/en/prod/0,2877,AD1845,00.html |
| 22:31.21 | prpplague | be more interested in an 8-bit one |
| 22:31.27 | flyback | mabye it is 8 |
| 22:31.39 | flyback | they have some i2c, spi etc ones also I noticed |
| 22:33.05 | flyback | ok I guess it is 8 bit or it double fetches |
| 22:33.12 | flyback | it has a fifo so it might be able to be 16 bit |
| 22:33.19 | prpplague | flyback: yea, 5v ttl |
| 22:33.29 | flyback | meaning good or bad for you? |
| 22:33.44 | prpplague | flyback: not very usable with current arm devices with level shifters |
| 22:33.49 | flyback | oh :/ |
| 22:34.02 | flyback | I have some projects though I can use this for |
| 22:34.15 | flyback | espically since I might already have some of the plcc version on some old isa soundcards |
| 22:34.34 | flyback | like I said they have several with different interfaces |
| 22:34.39 | flyback | they might have what you need |
| 22:34.57 | flyback | I noticed there was a ethernet chip maker too sold a 10/100 with dma etc |
| 22:35.01 | flyback | but it was straight out gpio |

| 23:10.19 | hapchap | prpplague: stick a fork in it is all i am saying |
| 23:10.34 | prpplague | hapchap: problem is that this one isn't compatible with anyone elses |

| 23:30.55 | flyback | that old codec |
| 23:30.58 | flyback | is biendian |
| 23:32.21 | ds2 | are there any rule of thumb about switchers that relate to efficiency vs voltage difference.... i.e. 48V bucking to 3.3V is more or less efficient then 12V to 3.3V? |
| 23:34.31 | MonMotha | ds2: higher Vin usually translates to higher efficiency |
| 23:34.45 | MonMotha | lower input current so lower average switch current |
| 23:35.03 | ds2 | Hmmm I see |
| 23:36.02 | ds2 | maybe a 12V Lead Acid would make a better bulk power source then a few LiIons |
