LIDAR-Lite Arduino Library

• Product Page: LIDAR-Lite v3 - See product page for operating manual
• Product Page: LIDAR-Lite v3HP - See product page for operating manual
• Product Page: LIDAR-Lite v4 LED - See product page for operating manual and device firmware updates
• Product Support - Please direct any support issues to Garmin's Support Team. They're smart, helpful, and super nice!

This library provides quick access to basic functions of LIDAR-Lite via the Arduino interface. Additionally, it can provide a user of any platform with a template for their own application code.

For detailed specifications, pinout, and connection diagrams, see the manuals linked at the above product pages.

A Note on Compatibility: Minor interface changes have occurred between LIDAR-Lite v3, v3HP, and previous versions. Backwards-compatibility of this library is largely preserved, though support is not directly provided for v1 and v2.

Installation instructions

To install, download this repository and place in your Arduino libraries folder or use the Arduino Library Manager. If you need help, follow the instructions here: http://arduino.cc/en/Guide/Libraries.

Example Sketches

v3/GetDistancePWM

This is the simplest demonstration of LIDAR-Lite. It shows how to read a distance using the PWM interface.

v3/GetDistanceI2c

This demonstration shows how to read distance using the I2C interface and choose preset configurations.

v3/ShortRangeHighSpeed

This example shows a method to run LIDAR-Lite at high speed for short range applications. It combines a variety of settings to trade off range and accuracy for very fast measurements.

v3HP/v3HP_I2C

This example shows various methods to run LIDAR-Lite v3HP.

v3HP/v3HP_MONITOR

Use the MODE pin to monitor STATUS of the LIDAR-Lite v3HP.

v3HP/v3HP_PWM

Use PWM output to read distances from LIDAR-Lite v3HP.

v4LED/v4LED

Various operation examples for LIDAR-Lite v4 LED.

v4LED/v4LED_fast

High rep rate example using the optional GPIO pins or I2C port to trigger measurements.

v4LED/v4LED_lowpower

Take single distance measurements using the I2C port in a lower power state.
