# Programming

## {{@218#bkmrk-open-iot-and-iiot-ga}}

### Install IDE

Please, follow the instructions located [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html) to install the ESP-IDF framework on your local machine. ESP-IDF is available both on [Windows](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/windows-setup.html) and [Linux](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/linux-macos-setup.html). It can also be installed through some popular IDEs: [VS Code](https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/install.md) or [Eclipse](https://github.com/espressif/idf-eclipse-plugin/blob/master/README.md).

ESP-IDF is required to build the examples written in C for the device. However, it can be also programmed in [MicroPython](https://docs.micropython.org/en/latest/esp32/tutorial/intro.html) ([Thonny](https://thonny.org/)).

### Connect the programmer

ESP32 IoT and IIoT Gateways can be programmed only with the external hardware programmer (for example [**P03**](https://doc.redisage.com/link/219#bkmrk-page-title)) connected via the Tag-Connect connector. After connecting it to the board and a PC, a new COM port should be available.
