Hello guys, I'm a newbie of netduino and I just read some thread from this forum to start my netduino robot project. finally I decide to use the DFRobot's motor shield. Unfortunately, When I hook up everything and run the sample from forum, Nothing happens to my motor. I'm pretty sure the motors works fine, so I think maybe something wrong with my wiring, Can you guys help to figure out what's wrong this it. I even wonder if the shield cannot work at all. I noticed the controller for this shield is L298P, but the demo code works on L298N, will this cause the problem? Here I attached the sample code. There's no compile error or run time exception happens at all. it just doesn't work for my motor. I set break point for these code and it seems work correctly. HBridge MotorDriver = new HBridge(new Netduino.PWM(Pins.GPIO_PIN_D6), Pins.GPIO_PIN_D7, new Netduino.PWM(Pins.GPIO_PIN_D5), Pins.GPIO_PIN_D4); // Motor 1 half speed backward MotorDriver.SetState(HBridge.Motors.Motor1, -50); // Motor 2 half speed forward MotorDriver.SetState(HBridge.Motors.Motor2, 50); // Lets run for 5 seconds Thread.Sleep(5000); // Motor 1 full speed backward MotorDriver.SetState(HBridge.Motors.Motor1, -100); // Motor 2 full speed forward MotorDriver.SetState(HBridge.Motors.Motor2, 100); // Lets run for 5 seconds Thread.Sleep(5000); // Stops both motors MotorDriver.SetState(HBridge.Motors.Motor1, 0); MotorDriver.SetState(HBridge.Motors.Motor2, 0);
