M5Atom Program Compilation and Flashing

1. Preparation

• Arduino IDE Installation: Follow the Arduino IDE Installation Tutorial to complete the IDE installation.
• Board Manager Installation: Refer to the Basic Environment Setup Tutorial to finish installing the IDE, M5Stack board manager, and select the development board M5Atom.
• Dependency Library Installation: Follow the Library Manager Installation Tutorial to complete the installation of the M5Atom driver library.

2. USB Driver Installation

Connect the device to the PC and open the Device Manager to install the FTDI driver for the device. Taking a Windows 10 environment as an example, download the driver file that matches your operating system, extract it, and install it through the Device Manager. (Note: In some system environments, you may need to install the driver twice before it takes effect. The unrecognized device name is usually M5Stack or USB Serial. It is recommended for Windows users to install the driver directly in Device Manager (custom update). The executable file installation method may not work properly).

For MacOS users, before installation, please check System Preferences -> Security & Privacy -> General -> Allow apps downloaded from: -> App Store and identified developers.

3. Port Selection

1. Connect the device to the computer via a USB cable. After completing the driver installation, you can select the corresponding device port in the Arduino IDE.

4. Program Compilation & Flashing

1. Open an example program from the driver library, click the upload button, and the program will automatically compile and flash.
