Garmin LIDAR-Lite v1 Silver Label Operating Manual page 8

Quick­Start Guide
Overview
1. Make Power and I2C Data Connections as per ​
optional connections and not required.
2. Initialization: Apply Power to the Module. The sensor operates at 4.75­5.5V DC Nominal, Maximum
6V DC
3. Measurement: Write register 0x00 with value 0x04 (This performs a DC stabilization cycle, Signal
Acquisition, Data processing). Refer to the section " ​
information about I2C Communications
4. Periodically poll the unit and wait until an ACK is received. The unit responds to read or write
requests with a NACK when the sensor is busy processing a command or performing a
measurement. (Optionally, wait approx. 20 milliseconds after acquisition and then proceed to read
high and low bytes)
5. Read: Register 0x0f, returns the upper 8 bits of distance in cm, register 0x10, returns the lower 8
bits of distance in cm. (Optionally a 2­Byte read starting at 0x8f can be done)
