00:19.24RobotGuyYou're a lively bunch today.
00:19.35SpeedEvilThe STM32 primer?
00:19.44RobotGuyHuh?
00:20.01SpeedEvilIdly wondering - I know it comes with tools drom renesas
00:20.44RobotGuySpeedEvil: I just got the Hew Target Server Demo Kit
00:21.21ohsixi got mine a week or two ago, the junk bluescreens every computer i tried it on so i haven't touched it since :]
00:21.36RobotGuyI followed the instructions and it won't work. Had previous Renesas tools installed, removed completely, reinstalled from HTS CD. No success.
00:21.37SpeedEvilRobotGuy: dunno that.

01:03.27RobotGuyYes, interesting
01:04.19g1powermac_PBwas attempting to replace a faucet but found the pipe hookups on the new one weren't long enough
01:04.35g1powermac_PBluckily I found this out before completely disassembling the old one
01:06.16g1powermac_PBanyway, at the store where we got the new faucet, I picked up a really nice multi-tool that was on sale :-)

11:47.56g1powermac_PBmorning GPSFan
11:49.04GPSFang1powermac_PB: g'day
11:50.36g1powermac_PBI'm looking at building this and attaching it to my zipit: http://www.analog.com/library/analogDialogue/archives/37-11/ecg.html
11:56.17GPSFanthat would be and interesting project. too bad the z2 has such a limited group of I/O comming out the back. the PXA270 is capable of so much more.
11:57.00g1powermac_PByea, going to have to use the 8052 controller in that schematic to do the processing before sending it to the zipit's pxa270
11:58.59g1powermac_PBhmm, I do need to find a replacement for the ADP3607 thats listed on the circuit
11:59.06GPSFanso the z2 would just be a display
11:59.11g1powermac_PBlooks like analog is phasing that chip out
11:59.34g1powermac_PBbasically
12:00.15GPSFanthere are lotsa of charge pump converters about. low noise and low power are important.
12:00.16GPSFanbbl
12:06.36g1powermac_PBthink I found a replacement: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1135

13:05.15g1powermac_PByou know, this analog 8051 is really, really nice
13:05.30g1powermac_PBit even has an i2c port, so I don't even need the i2c to uart chip
13:06.58g1powermac_PBits even got dma stuff for accessing its adc
13:08.59g1powermac_PBactually, I should be able to attach the gsm module directly to this sucker and let it handle the uart to i2c conversion for it
13:09.08g1powermac_PBless chips I need to buy
13:10.07g1powermac_PBnot sure though if it can handle the ecg stuff and passing commands to the gsm module at the same time though

16:36.43GPSFang1powermac_PB: hey, in 2.6.26-rc1 there is a new driver for the "QuickCapture" camera interface on the PXA270.
16:39.58g1powermac_PBGPSFan: ooo, interesting
16:40.19g1powermac_PBGPSFan: what about the usb device?
16:40.47g1powermac_PBI wonder when thats going to go into the mainline kernel
16:41.50GPSFanthe camera driver is. 2.6.26-rc1 came out yesterday, I was reading the changelog on kernel.org when I ran across that entry, as well as prpplagues Hammer patch.
16:43.00g1powermac_PBcool
16:44.12g1powermac_PBI wonder what would be more difficult, bringing that driver to 2.6.21.1 or bringing the zipit patches to 2.6.26
16:45.15g1powermac_PBobviously for 2.6.26, we'd need the jtag port
16:45.36g1powermac_PBwe might be able to get the camera driver going without kernel replacement on 2.6.21

18:44.00RobotGuyWow
18:45.34roxfansingers are people too...
18:45.51RobotGuyYes, they are.
18:47.28g1powermac_PByea, but its still cool that he chose our store

19:23.28Mr_Bongahi
19:25.15Mr_BongaI am working on an embedded system
19:25.58Mr_Bongaand I am building an aplication that could chage the local IP address of the system
19:26.15Mr_Bongahow can I do that on run time?

19:27.39Mr_Bongacan anyone help me??
19:27.51roxfanifconfig? (if it's unix)
19:28.47Mr_Bongabut how can I execut ifconfig on my code??
19:29.02Mr_Bongain c language
19:29.15roxfanthere are several versions of exec* call
19:29.34roxfani think there's also some generic api for that
19:29.43roxfanbut i don't know much about it...
19:29.50Mr_Bongahmmm
19:29.51Mr_Bonga:(
19:29.59roxfan(btw in irc getting answers 10 minutes after asking is nothing unusual)
19:30.14Mr_Bongaeheh
19:30.17g1powermac_PBhas done some programming that utilized syscalls
19:30.25g1powermac_PBbut it was quite a while ago
19:30.59Mr_Bongahmm
19:31.00g1powermac_PBis your embedded board running linux?
19:31.24Mr_Bongaand you don't remember g1powermac_PB ??
19:31.42Mr_Bongahow you did that
19:32.00g1powermac_PBwell, it still depends on what os you use
19:32.47roxfanhttp://www.usenet-forums.com/linux-networking/60477-changing-ip-address-progrmmatically.html
19:32.49Mr_Bongalinux monta vista
19:33.11g1powermac_PBhttp://linux.die.net/man/2/execve
19:33.25g1powermac_PBthat syscall will allow you run ifconfig
19:34.23g1powermac_PBroxfan: heh, yea, that way is prolly the preferred way of doing it
19:35.45g1powermac_PBdon't need ifconfig then
19:36.29g1powermac_PBMr_Bonga: http://linux.die.net/man/2/ioctl
19:36.37g1powermac_PBtheres info on the ioctl syscall
19:46.38Mr_Bongaok
19:47.11Mr_BongaI found info too : http://www.sourceware.org/ml/ecos-discuss/2004-04/msg00199.html
19:47.59Mr_Bongag1powermac_PB I have another question
19:48.52Mr_Bongasupose that my application has a listening socket on some port, and then I change the local IP
19:49.03Mr_Bongawhat happens??
19:49.21Mr_Bongathe listening socket wil still alive??
19:49.38Mr_Bongaor I have to close it ??
19:49.49Mr_Bongado understand my doubt?
19:50.25g1powermac_PBthat I don't know about
19:50.41RobotGuyYou would have to reinitialize the socket and connection
19:51.12RobotGuyNothing that doesn't have the new IP address would be able to communicate with your project.
19:52.15Mr_Bongayes RobotGuy, but you are talking about the client side, wright??
19:52.15RobotGuyMr_Bonga: Do you have some sort of DNS for your IP addresses?
19:52.46Mr_BongaI think no
19:52.50RobotGuyMr_Bonga: Do you have a domain?
19:53.08Mr_Bongano
19:53.19Mr_Bongabut why?
19:53.26RobotGuyMr_Bonga: OK, then when you change the IP address of your client, it has to reinitialize communication with any hosts it needs to communicate with.
19:53.47Mr_Bongayes
19:54.10RobotGuyMr_Bonga: If your application is a host, then all communications from clients will be broken when you change the IP address.
19:54.22Mr_Bongahmmm
19:55.13Mr_Bongareally??
19:55.15RobotGuyHost = Server
19:55.17RobotGuyYes
19:55.23Mr_Bongahmmm
19:56.05RobotGuyIf it is a host/server it would need to tell all the clients the new IP address before you change it.
19:56.06Mr_Bongabut if I had no connection , only a listening socket. It will broke to??
19:56.57RobotGuyMr_Bonga: If you have a listening socket, it is connected to your IP address. When the IP address changes, communication will be broken.
19:57.18Mr_Bongaok ok RobotGuy

19:57.29RobotGuyYou're welcome/
19:57.35Mr_Bonga:)
19:57.40Mr_Bongaanother question
19:57.41Mr_Bonga:)
19:58.24Mr_Bongamy kernel, on command line, don show the actual directory path
19:58.47RobotGuyYou mean your prompt in Linux?
19:58.48Mr_Bongahow can I "enable" it??
19:58.52Mr_Bongayes
19:59.01RobotGuyIt depends on what shell you are using.
19:59.38Mr_Bongasorry, but I don't understand
20:00.15RobotGuyThere are many different shells for Linux/UNIX - sh, bash, tcsh, ash, zsh, ksh, etc.
20:00.25RobotGuyEach has different processing for the prompt.
20:01.06RobotGuyEach has an initialization script that sets up things the way you want them.
20:01.17RobotGuyI use bash.
20:02.01Mr_Bongahow can I know what type of shell that my kernel are using??
20:02.48SpeedEvilkernel does not use shell
20:02.54SpeedEvilshell is run under a kernel
20:03.12SpeedEvilIt's like asking what kind of potatos can my toyota carry.
20:03.13adyerMr_Bonga: you can start by doing 'echo $SHELL'
20:04.13Mr_Bonga:)
20:04.57RobotGuyMr_Bonga: Did you do that and find what shell you are using?
20:05.37Mr_BongaI don't have my system here
20:05.38Mr_Bonga:(
20:06.37Mr_Bongabut I remember a file that the name its "loadmodules.sh"
20:07.17Mr_BongaI don't know if it helps
20:07.45Mr_BongaI am using montavista pro on a  Texas DM355
20:13.39Mr_Bonga??
20:16.59RobotGuyThat does not really help.  We need to know what shell it uses before we can help with your question about the prompt.
20:18.44Mr_Bongaok RobotGuy
20:19.32Mr_Bongatomorrow you wil be here??
20:20.09Mr_Bongacan I bother you?? :)
20:39.40RobotGuyI am often here.
