4.1. Instalacija drajvera

1. The board utilizes a CH340 USB-to-UART chip for communication and programming. Before connecting the board, ensure the appropriate CH340 drivers are installed on your computer. These drivers are typically available from the CH340 manufacturer's website or can be found through a quick online search.
2. After installing the drivers, connect the development board to your computer using the provided USB cable. Your operating system should recognize the device and assign a COM port.

4.2. Priključak za napajanje

The board operates at a voltage of DC 5V/3.3V. Power is typically supplied via the USB connection. Ensure your USB port can provide sufficient power. Avoid using uncertified power sources.

4.3. Postavljanje razvojnog okruženja

To program the STM32F407ZGT6, you will need a suitable Integrated Development Environment (IDE) and toolchain. Popular choices include:

• STM32CubeIDE: A free, all-in-one development tool from STMicroelectronics.
• Keil MDK-ARM: A widely used commercial IDE for ARM microcontrollers.
• IAR Embedded Workbench: Another commercial IDE with strong debugging capabilities.

Install your preferred IDE and ensure the necessary ARM Cortex-M4 toolchain and STM32F4 series device support packages are installed.

5. Uputstvo za upotrebu

5.1. Basic Programming Flow

1. Write Code: Develop your application code in C/C++ using your chosen IDE.
2. sastaviti: Compile your code within the IDE to generate an executable file (e.g., .hex or .bin).
3. Preuzmi: Use the IDE's built-in programmer or a separate utility (like STM32CubeProgrammer) to download the compiled code to the STM32F407ZGT6 MCU via the USB-to-UART interface (CH340).
4. Izvršiti: After successful download, the MCU will typically reset and begin executing your program.

5.2. Using Onboard Peripherals

• GPIO pinovi: The board exposes all MCU pins via header connectors. Refer to the STM32F407ZGT6 datasheet and reference manual for pin assignments and peripheral functions.
• Korisnička dugmad: The 4 independent user buttons can be configured as inputs for various control functions in your application.
• OLED/LCD Interface: Connect compatible OLED or LCD modules to the dedicated interface. Ensure correct pin mapping and driver implementation in your code.
• Mini SD Socket: Utilize the Mini SD card socket for data logging or external storage.
• SPI FLASH W25Q128: The onboard SPI Flash can be used for non-volatile data storage.

6. Održavanje

Proper care and maintenance will extend the lifespan of your development board.

• Rukovanje: Always handle the board by its edges to avoid touching components, especially the pins. Electrostatic Discharge (ESD) can damage sensitive electronic components. Use an anti-static wrist strap when handling the board.
• čišćenje: Ako je potrebno, nježno očistite ploču mekom, suhom četkom ili komprimiranim zrakom kako biste uklonili prašinu. Izbjegavajte upotrebu tekućina ili abrazivnih sredstava za čišćenje.
• Skladištenje: Čuvajte ploču u antistatičkoj vrećici na hladnom i suhom mjestu kada se ne koristi.
• Napajanje: Always use a stable and appropriate power supply (DC 5V/3.3V) to prevent damage.

7. Otkrivanje problema

If you encounter issues with your development board, consider the following troubleshooting steps:

• Ploča se ne uključuje:
  • Provjerite vezu USB kabela.
  • Ensure your computer's USB port is functional and providing power.
  • Verify the power indicator LED on the board is lit.
• Connection Issues (USB-to-UART):
  • Confirm that the CH340 drivers are correctly installed. Check Device Manager for any unknown devices or COM port errors.
  • Pokušajte s drugim USB portom ili kablom.
• Code Not Downloading/Running:
  • Ensure your IDE is configured for the correct MCU (STM32F407ZGT6) and programmer (CH340/UART).
  • Check for compilation errors in your code.
  • Press the onboard reset button after downloading code to ensure the MCU restarts.
  • Verify boot mode settings if applicable (though typically handled by the programmer).
• Periferni kvar:
  • Double-check your wiring and connections to external components.
  • Review your code for correct initialization and configuration of the peripheral.
  • Consult the STM32F407ZGT6 datasheet and reference manual for detailed peripheral information.
