  1. If you have any questions or suggestions, please send a message to my email or post it here and together we will discuss it. Greetings from Cartagena - Colombia
  2. - INTRODUCTION Hi everybody, I want to share a library for controlling a 4-pins PING sensor (HC-SR04 ICStation) basically, although you can also control the 3-pins PING))) sensor conventional of Parallax (URL). This library is a modification of the Caleb Zulawski's library for PING))) sensors. I made basic improvements in calculations, I added a function to calculate the distance in millimeters and added the option to change the "input trigger signal" [10uS for HC-SR04 and 5uS for PING)))] - CHANGE LOG v2.1 (26/08/2014) * Fixed calculations of distance in inches. v2.0 (25/08/2014) * Fixed problems with measurements adjustments. * New function for modification of a single unit. v1.0 (24/08/2014) * Basic modification of Caleb Zulawski's library. * Added the calculation of distace in millimeters. * Identified problems with measurements adjustments. - TESTING Tested on: Tiva C (TM4C123GXL) & Arduino UNO R3 - COMPARISON SECTION A small comparison between the 2 sensors is: * HC-SR04 sensor: 1. Working Voltage: 5V (DC) 2. Output signal: Electric frequency signal, high level 5V, 0V low level. 3. Sensor angle: Not more than 15 degrees. 4. Detection distance: 2cm-450cm. 5. High precision: Up to 0.3cm 6. Input trigger signal: TTL impulse 10uS 7. Mode of connection: 1. VCC 2. TRIG ( T ) 3. ECHO ( R ) 4. GND * PING))) sensor: 1. Working Voltage: 5V (DC) 2. Output signal: Electric frequency signal, high level 5V, 0V low level. 3. Sensor angle: Not more than 15 degrees. 4. Detection distance: 2cm-300cm. 5. High precision: Up to 0.3cm 6. Input trigger signal: TTL impulse 5us 7. Mode of connection: 1. GND 2. VCC 3. SG - DOWNLOAD SECTION v2.1: Ping4Pins v2.1.zip v2.0 (Not recommended): Ping4Pins v2.0.zip v1.0 (Not recommended): Ping4Pins v1.0.zip - INSTRUCTIONS OF INSTALLATION 1. Download the latest version of the library 2. Unzip the zip-folder. 3. Copy the "Ping4Pins" folder in the location of the libraries depending of your trainer: * For Arduino: <Arduino IDE directory>\hardware\libraries\ * For Tiva C: <Energia IDE directory>\hardware\lm4f\libraries\ Note: If you used an older version of the library, I recommend deleting the folder and copy the new folder "Ping4Pins". - EXAMPLES SECTION In the "examples" folder are 5 examples for Arduino and 5 examples for Tiva. I'll post the example # 1: /* Example # 1 for TivaC / Arduino Created by Jeyson Zuñiga Gomez (https://fb.me/jeysonzg) E-mail: ingjeysonzg@hotmail.com English: In this example, we will use the basic form of the Ping4Pins library. Español: En este ejemplo, vamos a utilizar la forma básica de la libreria Ping4Pins */ // English: We include the library that we will use, in this case Ping4Pins // Español: Incluimos la librería que vamos a usar, en este caso Ping4Pins #include <Ping4Pins.h> // English: Define Trigger and Echo pins // Español: Definimos los pines "Trigger" y "Echo" #define TriggerPin PF_4 #define EchoPin PD_7 // English: For Arduino use: // Español: Para Arduino usa: #define TriggerPin 8 #define EchoPin 7 // English: Create the ping variable with the builder Ping4Pins class and call the function Ping4Pins // Function: Ping4Pins(int Pin_Trigger, int Pin_Echo) // Español: Creamos la variable ping con el constructor de la clase Ping4Pins y llamamos a la funcion Ping4Pins // Funcion: Ping4Pins(int Pin_Trigger, int Pin_Echo) Ping4Pins ping = Ping4Pins(TriggerPin, EchoPin); void setup(){ // English: We start the serial monitor at a speed of 9600 baud // Español: Iniciamos el monitor serial a una velocidad de 9600 baudios Serial.begin(9600); } void loop(){ // English: We call the function "play", without parameters, of our Ping4Pins class. // Here the input trigger signal is 10us default. // Español: Llamamos a la funcion "play", sin parametros, de nuestra clase Ping4Pins. // Aqui la señal de entrada del disparo es de 10us por defecto. ping.play(); // English: We show in the IDE serial monitor the measurement in // microseconds, inches, centimeters and millimeters, respectively. // Español: Mostramos en el monitor serial del IDE la medicion en // microsegundos, pulgadas, centimetros y milimetros, respectivamente. Serial.print("Microseconds: "); Serial.print(ping.microseconds()); Serial.println(" uS"); Serial.print("Inches: "); Serial.print(ping.inches()); Serial.println(" in"); Serial.print("Centimeters: "); Serial.print(ping.centimeters()); Serial.println(" cms"); Serial.print("Milimeters: "); Serial.print(ping.milimeters()); Serial.println(" mm"); Serial.println(); delay(500); } - IMAGES SECTION Image 1. Image 2. Image 3. Image 4. NOTE 1: In Tiva we use digital pin PF_4 for TRIGGER and digital pin PD_7 for ECHO. In Arduino we use the digital pin # 8 for TRIGGER y digital pin # 7 for ECHO. NOTE 2: For use 3-pins PING))) Sensor with this library, declare TRIGGER and ECHO as same PIN DIGITAL. NOTE 3: Please excuse my English, I'm Colombian and my English is not very good
