Hi,everyone:
I face a urgent problem. I want to get variable value from tossim, and
follow the instruction of
TOSSIM
////////////////////////////////////////////////
# This is an example script from the TOSSIM tutorials.
# It can be used with any TinyOS application.
from tinyos.tossim.TossimApp import *
from TOSSIM import *
n = NescApp()
print n.variables.variables()
t = Tossim(n.variables.variables())
m = t.getNode(0)
for i in range(0, 1):
m = t.getNode(i);
time = ((79 + t.ticksPerSecond() / 100) * i + 1)
m.bootAtTime(time);
print "Mote " + str(i) + " set to boot at " + str(time);
for i in range(0, 500):
t.runNextEvent();
v = m.getVariable("'SimMoteP$startTime'")
v2 = m.getVariable("'SimSchedulerBasicP$m_head'");
print "start time: <", v.getData(), ">\nnext task: <", v2.getData(), ">"
for i in range(0, 500):
t.runNextEvent();
print "start time: <", v.getData(), ">\nnext task: <", v2.getData(), ">"
////////////////////////////////////////////////
I run this, (application has no problem) in simulation
but I always cannot get value
output::
////////////////////////////////////////////////
Mote 0 set to boot at 1
Could not find variable 'SimMoteP$startTime'
Allocated variable 'SimMoteP$startTime'
Could not find variable 'SimSchedulerBasicP$m_head'
Allocated variable 'SimSchedulerBasicP$m_head'
start time: < <no such variable> >
next task: < <no such variable> >
start time: < <no such variable> >
next task: < <no such variable> >
////////////////////////////////////////////////
but I can print value in n.variables.variables(),
imSchedulerBasicP.sim_scheduler_event_pending', 'simple', 'unsigned char',
'SimSchedulerBasicP.m_tail', 'simple', 'unsigned char',
'SimSchedulerBasicP.m_head', 'simple', 'unsigned char',
'SimSchedulerBasicP.m_next', 'array', 'unsigned char',
'SimSchedulerBasicP.sim_scheduler_event', 'simple', 'unknown',
'SimMoteP.bootEvent', 'simple', 'unknown', 'SimMoteP.startTime', 'simple',
'long long', 'SimMoteP.euid', 'simple', 'long long', 'SimMoteP.isOn',
'simple', 'unsigned char', 'TossimActiveMessageC.buffer', 'simple',
'unknown', 'TossimActiveMessageC.bufferPointer', 'simple', 'unknown',
'SerialActiveMessageC.buffer', 'simple', 'unknown',
'SerialActiveMessageC.sendMsgPtr', 'simple', 'unknown',
'SerialActiveMessageC.bufferPointer', 'simple',
'unknown',...............................
So anybody know the reason?
Thank you
Gavin
