- Forsyning Voltage: Connect a DC power source between 2V and 10V to the '+' and '-' terminals.
- Motorforbindelser: Connect Motor-A to the 'MOTOR-A' terminals and Motor-B to the 'MOTOR-B' terminals.
- Styresignalindgang: Connect your microcontroller's I/O pins to IN1, IN2, IN3, and IN4. The signal voltage range for these inputs is 1.8V-7V.
- IN1 and IN2 control Motor-A.
- IN3 and IN4 control Motor-B.

4.1 Using the ST-Link V2
Once connected, the ST-Link V2 can be used with compatible development environments such as IAR, KEIL, ST-LINK Utility, STVD, and STVP. Install the necessary drivers and software on your computer. Refer to the specific software documentation for detailed instructions on debugging, programming, and firmware updates for your STM8 or STM32 microcontroller.
4.2 Controlling Motors with the Dual H-Bridge
The Dual H-Bridge module controls DC motors based on the logic levels applied to its IN1-IN4 pins. The following table outlines the control modes for each motor:
A table illustrating the control logic for the Dual H-Bridge module, showing input combinations (IN1, IN2, IN3, IN4) for various motor operations like Forward, Reversion, Standby, and Brake for both Motor-A and Motor-B.
| DC MOTOR | MODE | IN1 | IN2 | IN3 | IN4 |
|---|---|---|---|---|---|
| MOTOR-A | Forward | 1/PWM | 0 | ||
| Tilbageførsel | 0 | 1/PWM | |||
| Standby | 0 | 0 | |||
| Bremse | 1 | 1 | |||
| MOTOR-B | Forward | 1/PWM | 0 | ||
| Tilbageførsel | 0 | 1/PWM | |||
| Standby | 0 | 0 | |||
| Bremse | 1 | 1 |
Note:
- "1" represents a high level; "0" represents a low level; "PWM" indicates a pulse width modulated wave, used to adjust the duty cycle to change speed.
- IN1 and IN2 control MOTOR-A; IN3 and IN4 control MOTOR-B. These two motor controls are completely independent.
- INx anti-input common conduction function: if a pin is floating, it is equivalent to a low input.
5. Vedligeholdelse
To ensure the longevity and reliable operation of your ST-Link V2 and H-Bridge modules, follow these general maintenance guidelines:
- Keep the devices in a dry environment, away from moisture and extreme temperatures.
- Avoid exposing the modules to static electricity. Handle them by the edges or use anti-static precautions.
- Periodically inspect connections for any loose wires or damage.
- Clean the modules gently with a soft, dry cloth if dust accumulates. Do not use liquids or harsh chemicals.
6. Fejlfinding
If you encounter issues with your ST-Link V2 or H-Bridge modules, consider the following troubleshooting steps:
- Forbindelsesproblemer: Double-check all wiring for correct pin assignments and secure connections. Ensure power supply is within the specified voltage rækkevidde.
- ST-Link V2 Not Detected: Verify that the ST-Link V2 drivers are correctly installed on your computer. Try a different USB port or cable. Ensure the target microcontroller is powered.
- Programming/Debugging Errors: Confirm that your development environment (IAR, KEIL, etc.) is configured for the correct microcontroller and ST-Link V2. Check for firmware updates for the ST-Link V2.
- Motor Not Responding: Check the power supply to the H-Bridge module and the motors. Verify that the control signals (IN1-IN4) from your microcontroller are correct according to the operating table. Ensure motors are properly connected.
- Motor overophedning: Ensure the motor current does not exceed the H-Bridge module's capabilities. Reduce load or operating time if necessary.
