7.4 Datalogger Programming
Short Cut is the best source for up-to-date datalogger programming code.
If your data acquisition requirements are simple, you can probably create and
maintain a datalogger program exclusively with
Short Cut . If your data
acquisition needs are more complex, the files that Short Cut creates are a great
source for programming code to start a new program or add to an existing
custom program.
Short Cut cannot edit programs after they are imported and edited
in CRBasic Editor .
A Short Cut tutorial is available in Section 4 , QuickStart
(p. 2)
. If you wish to
import Short Cut code into CRBasic Editor to create or add to a customized
program, follow the procedure in Appendix A , Importing Short Cut Code Into
CRBasic Editor
(p. A-1)
. Programming basics for CRBasic dataloggers are in the
following section. Complete program examples for select CRBasic dataloggers
can be found in Appendix
B , Example Program
(p. B-1)
. Programming basics
and programming examples for Edlog dataloggers are provided at
www.campbellsci.com\old-manuals .
