5.1 CRBasic Programming

The CR5000, CR800, CR850, CR3000, and CR1000 are programmed with

CRBasic; for details see the datalogger manual. While the instructions look

different than those used to program the older CR10X, CR23X, etc., they

perform similar functions. One difference that needs to be pointed out is that

with CRBasic measurement results are stored in a variable array, not numbered

input locations. In the older loggers the destination location is “indexed” so

that each pass through the measurement loop the result is stored in a higher

numbered location. In CRBasic the program must specifically increment an

index variable and use that variable to determine where each measurement is

stored.

GENERALIZED CRBASIC PROGRAMMING SEQUENCE:

ACTIVATE MULTIPLEXER/RESET INDEX

Portset (1 ,1) 'Set C1 high to Enable Multiplexer

I=0

BEGIN MEASUREMENT LOOP

SubScan(0,sec,16)

CLOCK PULSE AND DELAY

Portset (2,1 ) ‘Set port 2 high

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 49 50
