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.
| MOTOR CC | MODE | IN1 | IN2 | IN3 | IN4 |
|---|---|---|---|---|---|
| MOTOR-A | Endavant | 1/PWM | 0 | ||
| Reversió | 0 | 1/PWM | |||
| En espera | 0 | 0 | |||
| Fre | 1 | 1 | |||
| MOTOR-B | Endavant | 1/PWM | 0 | ||
| Reversió | 0 | 1/PWM | |||
| En espera | 0 | 0 | |||
| Fre | 1 | 1 |
Nota:
- "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. Manteniment
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. Solució De Problemes
If you encounter issues with your ST-Link V2 or H-Bridge modules, consider the following troubleshooting steps:
- Problemes de connexió: Double-check all wiring for correct pin assignments and secure connections. Ensure power supply is within the specified voltage gamma.
- 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.
