# ESP-IDF

The Espressif documentation is great to [get started](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/). We advise you to read it if you are not familiar with the ESP-IDF. If you've got any issue setting up the example, the solution can probably be found in the ESP-IDF documentation.

Below is a summary.

## Install ESP-IDF

{% tabs %}
{% tab title="Unix" %}

```
git clone --recursive https://github.com/espressif/esp-idf.git
cd esp-idf
./install.sh
. export.sh
idf.py set-target esp32
```

{% endtab %}
{% endtabs %}

Sourcing `export.sh` will set important environment variables that will be used when compiling the example. Make sure to use the same terminal window afterwards.

## Compile the example

Go to `examples/esp32` and run:

```
idf.py build
```

## Flash onto the Device

From `examples/esp32`, run:

```
idf.py [-p PORT] flash
```

## Monitor

Print the logs:

```
$ idf.py [-p PORT] monitor
