M5AtomEcho Program Compilation and Upload
1. Preparation
- Arduino IDE Installation: Refer to the Arduino IDE Installation Guide to complete the IDE installation.
- Board Manager Installation: Refer to the
Basic Environment Setup Guide
to complete the M5Stack board management installation and select the development board
M5Atom(the same controller is used for M5AtomEcho).
- Library Installation: Refer to the
Library Management Installation Guide
to complete the installation of the
M5Atomdriver library.
2. USB Driver Installation
Driver Installation Tip
Connect the device to the PC and open the device manager to install the
FTDI driver
. For Windows 10, download the driver files matching your OS, unzip them, and install them through the device manager. (Note: In some system environments, the driver may need to be installed twice to take effect. Unrecognized devices are usually named
M5Stack or USB Serial. Windows recommends using driver files for direct installation in the device manager (custom update); executable installation may not work properly).

Connect the device to the computer via a USB cable. After completing the driver installation, select the corresponding device port in the Arduino IDE.
4. Program Compilation & Upload
- Open the example program “EchoRest” from the driver library.
- Fill in the WiFi name and password in the code.
- Click the upload button to automatically compile and upload the program.
5. Program Effects
