e-puck2 radio module development

e-puck2 main wiki

1 Introduction

Espressif provides the Espressif IoT Development Framework (ESP-IDF for short), that is a framework for developing applications based on the Espressif ESP32 chip. The firmwares developed for the e-puck2 radio module are based on this framework.
The software development framework provided by Espressif is intended for rapidly developing Internet of Things (IoT) applications, with Wi-Fi, Bluetooth, flexible power management and other advanced system features.
Users can develop applications in Windows, Linux and MacOS based on ESP-IDF.
The C programming language is used to develop code for the radio module of the e-puck2 robot and the ESP-IDF includes the FreeRTOS real time operating system.

2 Development environment

In order to build the firmware you need to install the toolchain, refer to http://esp-idf.readthedocs.io/en/latest/get-started/#setup-toolchain.
Once installed you can issue the command make flash from the directory Projects\ESP32_E-Puck_2 to build the firmware.
For more information have a look at http://esp-idf.readthedocs.io/en/latest/get-started/#build-and-flash.

2.1 Debugging

You can debug your code by printing some information on the serial port, then from the PC you can read these information by opening the Serial Monitor port (have a look at the chapter Finding the USB serial ports used to know what ports are availables).

3 Get the source code

The radio module firmware source code can be downloaded with the command:
git clone --recursive https://github.com/e-puck2/esp-idf.git

3.1 WiFi

The radio module wifi firmware source code can be downloaded with the command:
git clone -b wifi --recursive https://github.com/e-puck2/esp-idf.git
