Guia de configuração
Follow these steps to set up your STM32 Nucleo Development Board:
- Check Jumper Positions: Ensure the following jumper settings are configured correctly:
- JP1: Off
- JP5 (PWR): On U5V side
- JP6 (IDD): On
- Conectar ao PC: Connect the STM32 Nucleo board to your PC using a USB Type-A to Mini-B cable. Use the USB connector labeled CN1 on the board to supply power.
- Verify Power and Communication LEDs: Upon successful connection, the red LEDs LD3 (PWR) and LD1 (COM) should light up. The green LED LD2 should blink, indicating communication activity.
- Test User Button: Press the user button B1 (located on the left side of the board). Observe how the blinking pattern of the green LED LD2 changes with each press, confirming basic board functionality.
