Definition:

#include <aSRF05.tea>




int aSRF05Mode1_ReadInt(

char trigger, char echo);

Parameters:

trigger	-	The digital pin index used to trigger the ranger.
echo	-	The digital pin index used to read from the ranger.  The digital pin must be connected to a pin capable of pulse width timing measurement.

Return Value:

The raw reading from the SRF05 ranging module in 1.6us increments.

Description:

This routine takes readings from a properly configured Devantech SRF05 Sonar Ranging Module. and reports the time-of-flight for the reading.  Mode 1 operation is backwards compatible with the SRF04 ultrasonic rangers.  This function is parametrized to allow mulitple rangers to operate on a single BrainStem module.  It is recommended to use this function when code size is not critical.  When using a single sensor in Mode 1 it is recommended to use the library routines in the aSRF04.tea library.

Example:

intVal = aSRF05Mode1_ReadInt(1,2);

The init (trigger) line is connected to digital pin 1 and the echo line is is connected to digital pin 2.  This would take a reading and set intVal equal to the time required for the ping to be received in 1.6us increments (this is round-trip echo return time).
