hello everybody....
i am having two doubts...
--->at first...
i hav successfully compiled and installed the modified the Delta application for external ADC signal...sampling time period is 10ms..
when i hav given a sinusoidal signal of 0.5V with an offset of 0.75V at 1 Hz from the signal generator...it was showing the sinusoidal signal...but the thing is ....the sinusoidal signal it was showing has lot of noise(when i used the oscilloscope)...like ...it was displaying a range of values around the exact value...
why this is happening ...is there is any adjustment tht i can do...
--->and ...the second one is...
if i sample the signal at 1ms(suppose for 50hz signal) then it will be better ...that is required for my application ...one more thing is that, the system tht i want to monitor is highly dynamic in nature..so the data should be send for every 1ms...i think 1ms is sufficient for just measuring the external ADC value..and sending this value using multihop(must) technique...
But the problem is..... i am losing lot of packets abt 50% even for the sampling period at 10 ms....
i hav seen tht in the given specifications of moteiv's module(tmote sky)..it is mentioned as 250 kbps...now in my application i am trying to use only 50 kbps...which is well in the limits...so it should work...
why it is so... can anybody pls give me the reason...
i hav been thinking abt this problem...from atleast 10 days.....
any help should be highly appreciated...
thanks
