4.2. Pemasangan Pemandu

The ATOM Lite uses a standard USB-to-Serial chip (typically CP2104 or CH9102F). Most modern operating systems will automatically install the necessary drivers. If the device is not recognized, you may need to manually install drivers:

• For Windows/macOS/Linux, search for 'CP2104 driver' or 'CH9102F driver' online and download from the official Silicon Labs or WCH webtapak.

4.3. Persediaan Persekitaran Pembangunan

The ATOM Lite supports various development platforms:

• IDE Arduino: Install the ESP32 board package in the Arduino IDE. Refer to the official ESP32 Arduino documentation for detailed instructions.
• MicroPython: Flash MicroPython firmware onto the device. Tools like `esptool.py` can be used for this.
• UI-FLOW: M5Stack's block-based programming platform. Download the UI-FLOW desktop IDE or use the web versi.
• ESPHome: For Home Assistant integration, visit esphome.io for pre-built projects and flashing instructions.

5. Operasi Asas

5.1. Using the Built-in Button

The ATOM Lite includes a programmable button (GPIO39). This button can be used for various user inputs, such as triggering events, changing modes, or confirming actions within your programmed application.

5.2. Controlling the RGB LED

The integrated RGB LED (connected to GPIO27) is a versatile indicator. It can be programmed to display different colors and patterns to convey status, alerts, or other visual feedback.

5.3. Infra-Red (IR) Communication

The IR LED allows the ATOM Lite to send infrared signals, enabling control of IR-compatible devices such as televisions, air conditioners, or other consumer electronics. Programming libraries are available for encoding and decoding IR protocols.

6. Menyambung Peranti

6.1. HY2.0-4P Interface

The HY2.0-4P connector provides a convenient interface for connecting M5Stack's Grove-compatible modules and other peripherals. This connector typically includes power (5V), ground, and two data lines (e.g., I2C, UART, or digital I/O).

6.2. External GPIOs

The ATOM Lite exposes additional GPIO pins (G19, G22, G23, G26, G32, G33) for direct connection to custom circuits, sensors, and actuators. Refer to the pinout diagram (Figure 5) for specific pin assignments and capabilities.

7. Penyelenggaraan dan Penjagaan

• Pastikan peranti kering dan jauh daripada lembapan.
• Elakkan daripada mendedahkan peranti kepada suhu yang melampau.
• Handle with care to prevent physical damage to the board and connectors.
• Clean the device with a soft, dry cloth if necessary. Do not use liquid cleaners.

8. Penyelesaian masalah

• Peranti tidak dikenali oleh komputer: Ensure USB-C cable is functional. Install appropriate USB-to-Serial drivers (CP2104/CH9102F) if not automatically detected.
• Program upload failure: Verify correct board and port selection in your IDE. Ensure drivers are installed. Try pressing the Reset button before uploading.
• Isu sambungan Wi-Fi: Check Wi-Fi credentials in your code. Ensure the device is within range of the Wi-Fi network.
• Tingkah laku yang tidak dijangka: Review your code for logical errors. Ensure all external connections are correct and secure.
