Definition:

#include <aSRF04.tea>




void aSRF04_Setup(

);

Return Value:

This routine does not return a value.

Description:

This routine sets up the Digital I/O needed to read values from the Devantech SRF04 Sonar Ranging Module.  The particular I/O pins used with this device must be specified in two define statements placed BEFORE the include statement for the aSRF04.tea file.  These two defined values are:

aSRF04_INIT
aSRF04_ECHO


The aSRF04_INIT pin can be any Digital I/O pin.  The aSRF04_ECHO pin must be a pin that has PTIME functionality (on the GP 1.0 module, digital pins 1-4 will work).

Example:

#define aSRF04_INIT aPortDigital2
#define aSRF04_ECHO aPortDigital3
#include <aSRF04.tea> /* after the defines */

aSRF04_Setup();


This would configure Digital I/O pins 2 and 3 for use in reading values from the Devantech SRF04 Sonar Ranging Module.
