5. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
This section guides you through the initial setup of your LILYGO T-32C3 module, including flashing firmware like MicroPython.
5.1 ഹാർഡ്വെയർ കണക്ഷൻ
- 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
എറിനു ശേഷംasing (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 webസൈറ്റ്.
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. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once the firmware is flashed, you can begin developing and running your applications on the T-32C3 module.
