[Tinyos-help] Measuring battery level
Hi all, I was wondering if there is a way to measure battery level of a sensor ? If there is, are there any modules/interfaces already developed, that one can use for that ? Any help is greatly appreciated, Demijan ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Installing TinyOS on Suse 10.0 x86_64
I had the same problem. Take a look in the readme/installation files of the java packages that you downloaded from that IBM site. You have to update the PATH variable and maybe something else - don't remember exactly. When I did that java and javac were found, but I still couldn't get the tinyos to run normally. Let me know if you succeed, jazzy79 Quoting Carlos Eduardo Rodrigues Lopes [EMAIL PROTECTED]: Hi everybody, I'm currently having trouble with Tinyos 1.1.0 installation on a Suse 10.0 for x86_64 (also tried the latest version 1.1.15 but also without success). I have followed installation instructions from TinyOS Website. - Downloaded the newest IBM java compiler (5.0) (instaled in /opt/ibm/java2-x86_64-50 folder) - Downloaded JavaCOMM the instalation were fine, no problems. Next I got all necessary packages (rpm). I haven't installed Graphviz 1.0 since I had a newer version on my system. The packages installation proceeded fine until tinyos-tools. The tinyos-tools didn't found the java virtual machine and aborted the installation script. Searching the web I found tinyos-tools spec file (http://www.tinyos.net/dist-1.1.0/tinyos/source/SPECS/tinyos-tools.spec) and followed the script instructions to finish installation manually (just typed install /usr/local/lib/tinyos/libgetenv.so /opt/ibm/java...). Installing the tinyos rpm, again it can't find neither java or javac. Again the script halt and installation was completed manually Considering installation finished I tried to complie Blink for mica2 and got a lot of linkage errors. Something like this: /tmp/ccRdmsSc.s:653: Error: unknown opcode `ledson' /tmp/ccRdmsSc.s:673: Error: `,' required /tmp/ccRdmsSc.s:673: Error: constant value required /tmp/ccRdmsSc.s:673: Error: garbage at end of line /tmp/ccRdmsSc.s:673: Error: unknown opcode `ledson' /tmp/ccRdmsSc.s:682: Error: expected comma after name `TimerM' in .size directive /tmp/ccRdmsSc.s:682: Error: unknown opcode `signalonet' /tmp/ccRdmsSc.s:682: Error: unknown opcode `signalonet' make: ** [build/mica2/main.exe] Erro 1 By the way, I'm using gcc 4.0.2 Have someone already installed tinyos on Suse? Had this problem? Can anyone help me? -- Carlos Eduardo Rodrigues Lopes Mestrando em Engenharia Eletrica - UFMG ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help -- ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
RE: [Tinyos-help] How to begin for RSSI for motes?
Amit, what you want to do is program the mote such that it will send the signal strength value in the payload of the packet (TOS_Msg.data). Then you'll be able to see it on PC. Hope that helps, Demijan Quoting #AMIT SATPATHY# [EMAIL PROTECTED]: Hi. I read the AM.h file and i saw the Msg- strength field. However, i also noticed that its only an internal value. Something that cannot be seen in the message packet sent to the PC. How do we extract this value from the radio to display on the PC? I have read the CC2420 datasheet but at the moment, i still cannot find any relevant material. Also, is this value sent from the original mote that is sending the packet or is it something that the base mote computes? Because if its something that the mote sends to the base mote, then it would be pretty useless. Thanks and regards. Amit. From: Sara B.

Take a look to AM packet format (AM.h) and you0ll see Msg-strength, that is RSSI value. For more information, you can read CC2420's data sheet. Regards, Sara. 2006/4/6, #AMIT SATPATHY# [EMAIL PROTECTED]: Hi! I am currently trying to learn up on RSSI for motes. But i have no idea where to begin from. I have tried looking through the apps folder in tinyos but i can't seem to find a program that uses RSSI. Could someone point me to a website or an application which starts off RSSI for beginners?
