6. First Program Upload: Connect the USB cable to your computer and the board. Use the "one-key download" feature or your IDE's programming tools to upload a simple test program (e.g., blinking an LED) to verify functionality.

5. Operating Instructions

This section outlines general operating procedures for the STM32F103C8T6 Development Board.

5.1 Programming the Microcontroller

• USB One-Key Download: The board supports direct program upload via the Micro USB port. Ensure your IDE is configured for this method.
• SWD Debug Interface: For advanced debugging and programming, connect an SWD (Serial Wire Debug) programmer/debugger to the dedicated SWD Debug Interface pins on the board.
• Boot Mode Selection: The board typically has boot mode selection jumpers (BOOT0, BOOT1) to choose between Flash memory, System memory (bootloader), or SRAM for booting. Refer to the STM32F103C8T6 datasheet for specific configurations.

5.2 Connecting Peripherals

• GPIO Pins: Utilize the exposed 20-pin I/O headers on both sides of the board to connect external sensors, actuators, and other modules. Refer to the STM32F103C8T6 datasheet and board schematic for pin assignments.
• Display Modules: Connect 1.44-inch/1.8-inch TFT LCD or OLED screens to the dedicated display interface pins. Ensure correct pin mapping (SPI, I2C, etc.) as per your display module's specifications.
• Powering External Components: The board provides 3.3V and 5V power output pins. Use these to power compatible external components, ensuring not to exceed the maximum current draw.

6. Maintenance

Proper maintenance ensures the longevity and reliable operation of your development board.

• Storage: Store the board in an anti-static bag when not in use to prevent electrostatic discharge (ESD) damage. Keep it in a dry environment, away from direct sunlight and extreme temperatures.
• Cleaning: If necessary, gently clean the board with a soft, dry brush or compressed air to remove dust. Avoid using liquids or abrasive materials.
• Handling: Always handle the board by its edges to minimize contact with components and prevent ESD.
• Power Off: Disconnect power before making any physical connections or disconnections to the board or its peripherals.

7. Troubleshooting

This section addresses common issues you might encounter.

• Board Not Powering On:
  • Ensure the USB cable is securely connected to both the board and a working USB port on your computer or power adapter.
  • Check if the USB port provides sufficient power (typically 5V).
  • Verify that the power indicator LED on the board illuminates.
• Computer Not Recognizing the Board:
  • Install or update the necessary USB drivers for the STM32 microcontroller.
  • Try a different USB port or cable.
  • Restart your computer.
• Program Upload Failure:
  • Ensure your IDE is correctly configured for the STM32F103C8T6 and the selected programming method (e.g., USB DFU, SWD).
  • Check boot mode jumper settings if applicable.
  • Verify that the program code is free of errors and compiles successfully.
  • Ensure no other software is using the serial port connected to the board.
• Peripheral Not Working:
  • Double-check all wiring connections between the board and the peripheral.
  • Verify that the peripheral is correctly powered.
  • Ensure your code correctly initializes and communicates with the peripheral (e.g., correct SPI/I2C addresses, pin assignments).
