  Please provide a link to the manual or datasheet for the VNH2SP30. It's impossible to tell for certain what needs to be connected to what without the documentation. Unlike the Arduino, the Stamp I/O pins are pretty much all the same (with some special exceptions that don't apply here). You can connect the INA,INB,CS,EN, and PWM signals to any convenient I/O pins on the Stamp. What's your level of experience with the Basic Stamp? What do you know about the VHN2SP30?

  HI Mike,
  This is the datasheet of the main chip VNH2SP30

  i want to know how make it work with BS2

  I don't recommend trying to drive this with a BS2. The BS2 doesn't have a PWM generator that can be used to drive a motor. It works ok for a DAC or light dimmer, but the PWM output can't be used to control a motor.
  
  Look at figure 32 in the datasheet for one way to connect this using 6 I/O pins. The problem will be the PWM input to the device. You might be able to get 100Hz, not the usual 20kHz pulses. In the past, you might have used a 556 dual timer to generate the fast pulses and control the timer from the BS2. These days, some other microcontroller can do the job easier.
  
  What's your level of experience?

  Thank you MIKE!
  I have little experience with BS2 and VNH2SP30,
  I'm using it since the last week.
