# LiDAR Library for Arduino
Laser distance scan sensor (LIDAR) Arduino wrapper/controller for [kaia.ai](https://kaia.ai) home robot software platform.
Please check out the [Awesome 2D LiDARs list](https://github.com/kaiaai/awesome-2d-lidars)
and read this [blog post](https://kaia.ai/blog/arduino-lidar-library/) for more details.
Please visit the [Support Forum](https://github.com/makerspet/support/discussions/)!
This library supports:
- YDLIDAR X4, X4-PRO, X3, X3-PRO, X2/X2L, SCL models
- SLAMTEC RPLIDAR A1
- Neato XV11/Botvac
- Xiaomi Roborock Mi 1st gen LDS02RR
- 3irobotix Delta-2A, Delta-2B, Delta-2G, Delta-2A 115000 baud
- Note: there is a fixed pattern noise issue that needs debug
- LDROBOT LD14P
- CAMSENSE X1
Other models are in the works.

## Example Code
Please see the `examples` folder for sample Arduino sketches.
## Connecting to Arduino
Please follow [this tutorial](https://kaia.ai/blog/tutorial-connect-ld14p-lidar/) to connect LDROBOT LD14P to Arduino ESP32.
### Adapter Boards
Some LiDAR/LDS models do not have built-in motor control and therefore require an additional board to operate:
- for Xiaomi Roborock 1st gen LDS02RR use [this board](https://github.com/makerspet/pcb/tree/main/lds02rr_adapter)
- for Neato XV11 use [this board](https://github.com/makerspet/pcb/tree/main/neato_delta_adapter)
- for 3irobotix Delta-2A, -2B, -2C PRO, -2D, -2G use [this board](https://github.com/makerspet/pcb/tree/main/neato_delta_adapter)
### ESP32 Module Variants
- When using the ESP32 WROVER board, it's worth using pins 32 and 33 instead of pins 16 and 17, which are used for QSPI
- ESP32-S3 has only two UARTs, as opposed to ESP32 having 3 UARTS
- When using the YD ESP32-S3, consider the default TX1, RX1 GPIO15 and GPIO16 pins and change the example code to `HardwareSerial LidarSerial(1);`
```
//ESP32-S3
//HardwareSerial LidarSerial(2);
HardwareSerial LidarSerial(1);
...
//LidarSerial.begin(baud_rate); // Use default GPIO TX 17, RX 16
LidarSerial.begin(baud_rate, SERIAL_8N1, 16, 15); // GPIO16 as RX1, GPIO15 as TX1
```
- ESP32-C3 has only two UARTs, as opposed to ESP32 having 3 UARTS
- use UART1 for LiDAR and, for example, GPIO4 as RX1 and GPIO5 as TX
```
//ESP32-C3
//HardwareSerial LidarSerial(2);
HardwareSerial LidarSerial(1);
...
//LidarSerial.begin(baud_rate); // Use default GPIO TX 17, RX 16
LidarSerial.begin(baud_rate, SERIAL_8N1, 4, 5); // GPIO4 as RX1, GPIO5 as TX1
```
## Performance Notes
- currently Delta-2A, -2B, -2G exhibit mysterious fixed pattern noise
- this noise does NOT show when using 3irobotix development kit, so it should be fix-able (somehow)
- so far I haven't heard back from 3irobotix support.
