10. Datalogger Program
All stations are pre-programmed to suit the ordered configuration options, with a user editable CRBasic program.
The CRBasic files are supplied as
Open-Source Software , allowing viewing, and editing of the code. CRBasic files
may be edited in a basic text editor such as Notepad or using the feature rich CRBasic editor
(
www.campbellsci.com/crbasiceditor
22
). The program may be downloaded directly from the Ai1.
If a module is missing, the wrong version used, or the user program contains an error, a compile error will be
generated. CRBasic editing is an advanced topic and is not included in standard product support. Custom
engineering may be performed with a support agreement. As the software is in rapid development, the OS features
will continue to be enhanced. The testing with a new OS library file is up to the end user to ensure compatibility
with the Ai1 hardware configuration provided. Backward compatibility is not guaranteed. All library files are open-
source and may be user edited if desired.
It is possible to compile the include programs into a single file, eliminating Ai1OS
code related to options that are not used (improves readability, simplifies finding
bugs and reduces the time to transfer files). Select
Conditional Compile, Include
Files and Save from the Compile pulldown menu, and specify the filename (which
must be different to the current filenames). It is also possible to compress the
program (remove comments and whitespace) for low-speed communications links.
Select
Create Compressed File from the Edit menu. This is the default setting.

The CRBasic is a licenced program, refer to support for pricing. CRBasic is available for free as an inclusion with PC400 which only needs an email address for registration, available:
