Hi,
 
I am now reading lesson 5 of tinyos-2 tutorial. I had a problem with the 
DemoSensorC in oscilloscope application. 
 
I am now using micaz and tinyos-2 without sensor board. I installed the 
oscilloscope application. It works. However, the data are almost constant 
around 440 in the display panel. I tried both SineSensorC and different 
valued ConstantSensorC in DemoSensorC. But the data are still the same 
(always around 440).  Since there is no sensor board, I did not specify 
SENSORBOARD when I installed the oscilloscope application, that is, I just used 
"make micaz reinstall,1 mib510,/dev/ttyS10". The DemoSensorC file I modified 
was in /tos/platforms/micaz. I assumed that if I used SineSensorC, I 
should get a sinusoid and if I used different values in ConstantSensorC, I 
should get lines in different place. The DemoSensorC.nc is very simple, I do 
not know where I should change the code.
 
I would appreciate it very much if anyone could let me know what's the 
problem and how to solve it.
 
Thank you very much. I look forward to hearing from you.
 
Liang Hong
