• Download WiringPi library

    git clone git://git.drogon.net/wiringPi
    cd wiringPi
    git pull origin
    cd wiringPi
    ./build
  

• Use the Sonar class as follows:

    Sonar sonar;
    int distance = sonar.distance(30000); // 30000 is a timeout in microseconds

Which GPIO pins to connect to Raspberry Pi?

I am having a issue in determining which pins to connect the HC-SR04 to my Pi. Is there a parameter option to define the pins?

I have the sensor confirmed working with a python script on GPIO 18 & 24 and this is not a I2C device.

Thanks!

What is the licensing for this code?

Hi,

As the code's author and copyright holder, what rights do you grant for the code in terms of use? I can't seem to find a LICENSE.md file.

Paramater timeout now used in libSonar.cpp

Hi,
I was taking a look at the libSonar.cpp and realised the parameter "timeout" was not used in double Sonar::distance(int timeout). I believe it is meant to be used in this line of code while (digitalRead(echo) == LOW && micros()-now<30000);.

Too high cpu usage

This is working well on my RaspberryPi but I get a high cpu usage just for measuring a distance.
¿Do you know how to avoid it?

I'm trying to develop something with wiringPiISR but I'm having problems when I want to connect more than one sensor at the same time.
