HC-SR04 Ultrasonics sensor - ArduinoIO package

Hi, I need to measure the distance using the HC-SR04 ultrasonic sensor with the help of simulink (arduinoIO package or arduino target). It is really hard because in arduino IDE i can use the pulsein() function which would give me the elapsed time of the echo signal and fire pulses for the trigger pin too. So is there a way to do this in simulink?

Can I make my own simulink block for this sensor interface using S-function and place it in my ArduinoIO library?

Guys, you justo gotta code on the adioes.pde I just used the function analog read, which i wouldnt use for my project, and replaced it with my hcsr04 basic code. Then, my analog read block gives me the distance measured on my ultrasonic sensor via code on the firmware. Did u get it?
