-// I2C SRF10 or SRF08 Devantech Ultrasonic Ranger Finder
-// by Nicholas Zambetti <http://www.zambetti.com>
-// and James Tichenor <http://www.jamestichenor.net>
-
-// Demonstrates use of the Wire library reading data from the
-// Devantech Utrasonic Rangers SFR08 and SFR10
-
-// Created 29 April 2006
-
-// This example code is in the public domain.

-{
- Wire.begin(); // join i2c bus (address optional for master)
- Serial.begin(9600); // start serial communication at 9600bps

-int reading = 0;
-
-void loop()
-{
- // step 1: instruct sensor to read echoes
- Wire.beginTransmission(112); // transmit to device #112 (0x70)
- // the address specified in the datasheet is 224 (0xE0)
- // but i2c adressing uses the high 7 bits so it's 112
- Wire.write(byte(0x00)); // sets register pointer to the command register (0x00)
- Wire.write(byte(0x50)); // command sensor to measure in "inches" (0x50)
- // use 0x51 for centimeters
- // use 0x52 for ping microseconds
- Wire.endTransmission(); // stop transmitting
-
- // step 2: wait for readings to happen
- delay(70); // datasheet suggests at least 65 milliseconds
-
- // step 3: instruct sensor to return a particular echo reading
- Wire.beginTransmission(112); // transmit to device #112
- Wire.write(byte(0x02)); // sets register pointer to echo #1 register (0x02)
- Wire.endTransmission(); // stop transmitting
-
- // step 4: request reading from sensor
- Wire.requestFrom(112, 2); // request 2 bytes from slave device #112
-
- // step 5: receive reading from sensor
- if(2 <= Wire.available()) // if two bytes were received
- {
- reading = Wire.read(); // receive high byte (overwrites previous reading)
- reading = reading << 8; // shift high byte to be high 8 bits
- reading |= Wire.read(); // receive low byte as lower 8 bits
- Serial.println(reading); // print the reading
- }
-
- delay(250); // wait a bit since people have to read the output :)
