int aSRF04_ReadInt(

);

Return Value:

The raw reading from the SRF04 ranging module in 1.6us increments.

Description:

This routine takes readings from a properly configured Devantech SRF04 Sonar Ranging Module. and reports the time-of-flight for the reading.  This function is ideal when a single ranger is being used with a BrainStem and code size is must be kept to a minimum.  When multiple rangers are intended to be used with a BrainStem, it is recommended to use the aSRF05Mode1_ReadInt routine.

Example:

intVal = aSRF04_ReadInt();

This would take a reading and set intVal equal to the time required for the ping to be received in 1.6 uSec. increments. (This is round-trip echo return time.) The aSRF04_Setup routine must be called prior to calling this routine.
