User Guide

Environment Setting

The software framework for ESP32 series development boards is completed, and you can use CircuitPython, MicroPython, and C/C++ (Arduino, ESP-IDF) for rapid prototyping of product development. Here's a brief introduction to these three development approaches:

  • CircuitPython is a programming language designed to simplify coding tests and learning on low-cost microcontroller boards. It is an open-source derivative of the MicroPython programming language, primarily aimed at students and beginners. CircuitPython development and maintenance are supported by Adafruit Industries.
    • You can refer to development documentation for CircuitPython-related applications development.
    • The GitHub library for CircuitPython allows for recompilation for custom development.
  • MicroPython is an efficient implementation of the Python 3 programming language. It includes a small subset of the Python standard library and has been optimized to run on microcontrollers and resource-constrained environments.
  • The official libraries and support from Espressif Systems for C/C++ development make it convenient for rapid installation.
    • Users can select Arduino
    • Visual Studio Code (ESP-IDF) as their Integrated Development Environment (IDE).
  • The environment is set up under Windows 10, users can choose to use Arduino or Visual Studio Code (ESP-IDF) as IDE for development. For Mac/Linux OS users please refer to the official instructions.

Arduino

Install Arduino IDE

  • The following development system is Windows.
1. Open the official software download webpage, and choose the corresponding system and system bits to download.

Create Example

  • The following example is about how to make LED blinking. (File -> examples -> Blink under 01.Basics)

R7FA4 PLUS B Example.jpg

  • Select the development board and COM ports.

Search "Nano ESP32", select "Arduino Nano ESP32", and then click on OK (the following picture is for reference only, you need to select the corresponding board.)

Open Example

  • Open the existing example, it is easier to operate. Directly run the ".ino" demo and refer to the operation above, and select the corresponding board and COM port to download and compile.

R7FA4 PLUS A Open.jpg

  • ESP32-S3-Nano opens the Arduino demo: Open File -> Examples. These demos can be directly used without other external libraries.

MicroPython

1. Download and install the latest Thonny IDE, open Thonny IDE -> Configure interpreter... as shown below:
CircuitPython Thonny06.jpg
2. Press the BOOT key on the board, connect to the USB cable, and find the Device Manager or the corresponding COM port. Download or run the demo, and you can see the Hardware Connection for more details.
3. According to the steps below, download the online MPY firmware of the ESP32 series, and clean the Flash content of the development board before downloading, and the whole process may last 1 minute.
