5. Persediaan dan Pemasangan
This section guides you through the initial setup of your LILYGO T-32C3 module, including flashing firmware like MicroPython.
5.1 Sambungan Perkakasan
- Connect the T-32C3 module to your computer using a compatible USB-to-serial converter or a development board that provides USB connectivity. Ensure proper wiring of TX, RX, VCC (3.3V), and GND.
- Verify that your computer recognizes the serial port. You may need to install appropriate USB-to-serial drivers (e.g., CP210x or CH340 drivers).
5.2 Flashing MicroPython Firmware
To program your board with MicroPython, you will typically use the esptool.py utility. Ensure Python is installed on your system and esptool is installed (pip install esptool).
Step 1: Erase Flash (First-time setup)
If this is the first time you are flashing MicroPython or if you want to clear all previous data, erase the entire flash memory:
esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flashNote: Replace /dev/ttyUSB0 with the actual serial port of your module (e.g., COMx on Windows).
Step 2: Program Firmware
Selepas erasing (or if you're updating firmware), program the MicroPython firmware. You will need a MicroPython .bin file for ESP32-C3. Download the latest stable firmware from the official MicroPython webtapak.
esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x0000 esp32-20190125-v1.10.binNote: Replace esp32-20190125-v1.10.bin with the actual filename of your downloaded firmware. The baud rate (460800) can be adjusted if needed.
6. Arahan Operasi
Once the firmware is flashed, you can begin developing and running your applications on the T-32C3 module.
- Hidupkan kuasa: Connect the module to a stable 3.3V power supply. If using a development board, power is typically supplied via USB.
- Code Upload: Use an Integrated Development Environment (IDE) like Thonny (for MicroPython) or the Arduino IDE (with ESP32-C3 board support) to write and upload your code.
- Serial Monitor: Utilize the serial monitor in your IDE to view output from your program and debug.
- Wi-Fi/Bluetooth: Implement Wi-Fi and Bluetooth functionalities in your code to connect to networks, other devices, or cloud services. Refer to the ESP-IDF programming guide or MicroPython documentation for specific API usage.
7. Penyelenggaraan
