Re: [Tinyos-help] Why microsecond accuracy in FTSP with telosb?

Hi Janos, thank you too for the answer. So when I created the graphs with matlab file (FtspDataAnalyzer.m) the results were in jiffy, but in this case jiffy means millisecond, right? -- View this message in context: http://tinyos-help.10906.n7.nabble.com/Why-microsecond-accuracy-in-FTSP-with-te

The FTSP paper refers to a TinyOS 1.x-based implementation, and that one does microsecond-precision timestamping on micaz. In TinyOS 2.x, the HIL only requires millisecond-precision timing, and that's what FTSP relies on. In that case, 1 jiffy is about 1 millisecond (1/1024 second, to be specific)

Hi, Fairly simple, the FTSP paper was based on the Mica2 (or was it the MicaZ?) which has a higher frequency crystal. You can do a similar thing with the TelosB, but you will have to change some of the code. Search the mailing list. There were long threads discussing how to do that. Cheers, - Th

Hi guys, I'm a newbie in tinyos. I read the FTSP paper and i tested FTSP following the readme to verify the accuracy. I tested the algorithm on 10 motes and on the other two motes I used BaseStation and RadiocountToLeds just like described in the readme and then I followed the readme.matlab. The l

you never really state what the problem you are trying to solve or running into. Other than to say you don't know how to do something. you won't get much help with that. i'd suggest you start working through the tutorials until something gels and you figure out how to do what you want. On Fri

Hi Eric, Thanks for the swift reply, and apologies for not being more specific - I am using TelosB. I've read inquiries about roughly similar problems before, mostly in MSP430 forums and in the context of UART streams, not ADC streams. Circular queues were mentioned, as well as swapping buffers. A
