Arduino library for the [Apis](https://github.com/NorthernWidget/Project-Apis) LiDAR rangefinder board. Apis manages power supply, firmware watchdog, and I2C communication for a LiDAR Lite unit, and reads a MEMS accelerometer to report pitch and roll — useful when the sensor is not mounted level.

**Installation:** included in [NorthernWidget-libraries](https://github.com/NorthernWidget/NorthernWidget-libraries). Also available via the Arduino Library Manager.

```cpp
#include <Apis.h>

Apis rangefinder;

void setup() {
    Serial.begin(9600);
    rangefinder.begin();
    Serial.println(rangefinder.getHeader());
}

void loop() {
    Serial.println(rangefinder.getString());
    delay(1000);
}

See examples/ for a complete demo and Margay logger integration.
