7.4 Programming
Short Cut is the best source for up-to-date datalogger programming code.
Programming code is needed when:
•
Creating a program for a new datalogger installation
• Adding sensors to an existing datalogger program
If your data acquisition requirements are simple and you are connecting the
sensor to a pulse port, 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
provided in the following sections. Complete program examples for select
CRBasic dataloggers can be found in Appendix B , Example Programs
(p. B-1)
.
Programming basics and programming examples for Edlog dataloggers are
provided at www.campbellsci.com/old-manuals .
7.4.1 Wind Speed
Wind speed is measured with the Pulse Count instruction ( PulseCount() in
CRBasic. Use the low level AC configuration.
The expression for wind speed (U) is:
U = MX + B
where
M = multiplier
X = number of pulses per second (Hertz)
B = offset
