Programming Examples
Programs are created on a TI calculator to set up specific CBL 2 operations, depending
on the experiment that you want to perform. Samples of various types of programs
follow. Each program includes both program commands and comments explaining
what the commands do.
Example 1: Temperature Non-Realtime Data Collection
:ClrAllLists
:ClrHome
:Send({0})
:Send({6,4})
:Send({1,1,1})
:Send({3,.1,100,0})
:Get(L
)
2
:Get(L
)

:Plot1(Scatter,L
:ZoomStat
Example 2: Temperature Realtime Data Collection
:ClrAllLists
:PlotsOff:Func
:FnOff:AxesOn
:1üXmin:30üXmax:1üXscl
:M20üYmin:60üYmax:.1üYscl
:ClrHome
:Send({0})
:Send({6,4})
:Send({1,3,1})
:30üdim(L
)
2
:Send({3,1,M1,0})
:ClrDraw
:For(I,1,30,1)
:Get(L
(I))
2
:Pt-On(I,L
(I))

:End
Example 3: Distance and Velocity Non-Realtime Data Collection
:PlotsOff
:ClrAllLists
:ClrHome
