PROBLEM WITH A SCRIPT ON RIOX CARD

My problem is that i would connect and test an HCSR04 ultrasonic sensor with my riox card, someone know how it do?

please circuit scheme and an example for this situation on microbasic script

Hey Davide,

If you are still having trouble connecting this, you should take a look at Parallax's PING sensor . They implement the trigger signal
using integrated circuitry on the sensor itself, so all you have to do is monitor the output signal using a pulse output.

Isko my problem is that i dont know how to write the script because , when i was using arduino , the command for input an inpulse was "PULSEIN" but in microbasic the "pulse in " command " there isn't.
so i dont know how to program it . Now i connect the trigger on an outpup and the echo signal on an input, so the last thing that remain is the code for the script , i just see the parallax ultrasonic sensor , but my sensor have 1 VCC , 2 GND , 3 ECHO, 4 TRIGGER.
And i must connet this pin on the riox card before writing a script
