Data Sheet

Arduino UNO sketch to show minimal coding required to read distance from tinyLiDAR

This program will continually print the measured distance from tinyLiDAR which

is operating in its default single step mode.

Notes:

This code requires the "Arduino I2C Master Library rev5" library to allow the

standard I2C stretch feature to work properly on the UNO.

** Please install it before running this sketch. **

The library can be downloaded from here:

while(1)

{

I2c.write(0x10,'D'); //take single measurement

I2c.read(0x10,2); // request 2 bytes from tinyLiDAR

i = I2c.receive(); // receive MSB byte

i = i<<8 | I2c.receive(); // receive LSB byte and put them together

Serial.println(i); // print distance in mm

delay(100); // delay as required (30ms or higher in default single step mode)
