Programming

Short Cut is the best source for up-to-date programming code for Campbell Scientific data loggers. If your data acquisition requirements are simple, you can probably create and maintain a data logger 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.

A Short Cut tutorial is available in QuickStart. If you wish to import Short Cut code into CRBasic Editor to create or add to a customized program, follow the procedure in Importing Short Cut code into CRBasic Editor. Programming basics for CRBasic data loggers are provided in this section. Complete program examples for select CRBasic data loggers can be found in Example programs.

Use the SDI12Recorder() instruction to measure the sensor. This instruction sends a request to the sensor to make a measurement then retrieves the measurement values from the sensor. See SDI-12 measurements for more information.

For most CRBasic data loggers, the SDI12Recorder() instruction has the following syntax:

The Destination parameter must be an array. The required number of values in the array depends on the command (CS650 SDI-12 commands).

FillNAN and WaitonTimeout are optional parameters (refer to CRBasic Help for more information).
