# VL53L8CX library for ESP32

A vl53l5cx library for esp32 using the **esp-idf framework**. This library is based
on [ST's  Ultra Lite Driver (ULD) for VL53L8CX](https://www.st.com/content/st_com/en/products/embedded-software/imaging-software/stsw-img040.html)
v.1.2.1. This library is just an adaptation of the ST's library for esp-32.

> **Warning**
> This Library is **not** compatible with Arduino framework

## Getting started
### Wiring for the SATEL-VL53L8

For the examples this is the used wiring, but feel free to modify it and adapt it for your needs.

### Library Installation 📥

The library is available at https://components.espressif.com/components/rjrp44/vl53l8cx.

So, you can use the [IDF Component Manager](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html) to easily import this library into your project.
To add this component to your project, run:

```log
idf.py add-dependency "rjrp44/vl53l8cx^1.1.0" 
```


## Examples 📄

You can find in `📁 ./examples` ST's examples adapted for ESP32 with I²C. For more information about the available features read [UM3109](https://www.st.com/resource/en/user_manual/um3109-a-guide-for-using-the-vl53l8cx-lowpower-highperformance-timeofflight-multizone-ranging-sensor-stmicroelectronics.pdf).

## Usual errors 🐛
### Stack overflow error 💽

If by running an example you get a stack overflow error, this means that your main stack size is too small.
```log
***ERROR*** A stack overflow in task main has been detected.
```
**Increase the main stack size :**

Run `idf.py menuconfig`. Go to Component Config -> ESP System settings and increase the Main task stack size to at least `7168`.
