Hi!

 

Anybody has experience SB with DFRobot L298P using HBridge, no errors motor doesn't rotate

 

Here the code

 

 

using System;

using System.Threading;

using Microsoft.SPOT;

using Microsoft.SPOT.Hardware;

using NetduinoGo;

using SecretLabs.NETMF.Hardware;

using SecretLabs.NETMF.Hardware.NetduinoGo;

using Toolbox.NETMF.Hardware;

 

namespace DFRobotMShield

{

    public class Program

    {

        public static void Main()

        {

            // write your code here

            Thread.Sleep(5000);

            NetduinoGo.ShieldBase sb = new NetduinoGo.ShieldBase((GoBus.GoSocket)4);

 

            HBridge MotorDriver = new HBridge(sb.PWMChannels.PWM_PIN_D6, sb.Pins.GPIO_PIN_D7, sb.PWMChannels.PWM_PIN_D5, sb.Pins.GPIO_PIN_D4);

 

            MotorDriver.SetState(HBridge.Motors.Motor1, -50);

         

            //Thread.Sleep(Timeout.Infinite);

            while (true) ;

 

        }

 

    }

}

Hi,

 

From the manual; http://www.dfrobot.c...N)_(SKU:DRI0009)

You can select PWM and PPL mode with jumpers. The only supported mode with this class is PWM. Could you check if you have your jumpers set correctly?

 

Also, what are the specifications of your motors and power supply? Do the motors make a sound? It can be that they just won't get enough power.

Thanks Stefan, I found the solution from absolutely different angle , but without your tip I wouldn't get it, it's somehow different MS, no PWM/PLL switch, and what happened it was different pins I will post later today pic of the shield, but it was shipped by robotshop.com in dfrobot wrappinf with df robot logo on it

 

Actually  is there class to control stepper with it?
