Help with motor shiel r.3 (library AFMotor)

Help a newbie to understand.
There arduino uno R.2 and motor shield R.3 (2 motors).
The library does not work with AFMotor Shield v.3.

So, the actual question. What and where you need to change the code library to correctly assign pins?

In such a situation (without having to connect the library) it works:
PWM_a control for motor outputs pin 3
PWM_b control for motor outputs pin 11
direction_a control for motor outputs pin 12
direction_b control for motor outputs pin 13

The library does not work with AFMotor Shield v.3.

A google search for Arduino library reveals that there are two or three (or more) libraries. Which one are you referring to?

What does "does not work" mean? Does not compile? Does not set direction correctly? Does not set speed correctly? Something else?

I use the library by downloading the link: Motor Shield - Arduino motor/stepper/servo control

When you run the motor test (for example from the library), the command does not work
"FORWARD, BACKWARD and RELEAS"

If istolzovat this code, everything works:

int pwm_a = 3; / / PWM control for motor outputs 1 and 2 is on digital pin 3 (or 5,6)
int pwm_b = 11; / / PWM control for motor outputs 3 and 4 is on digital pin 9 (or 10,11)
int dir_a = 12; / / direction control for motor outputs 1 and 2 is on digital pin 2 (or 4,7)
int dir_b = 13; / / direction control for motor outputs 3 and 4 is on digital pin 8 (or 12,13)

void setup ()
{
pinMode (pwm_a, OUTPUT); / / Set control pins to be outputs
pinMode (pwm_b, OUTPUT);
pinMode (dir_a, OUTPUT);
pinMode (dir_b, OUTPUT);
analogWrite (pwm_a, 50); / / set both motors to run at (100/255 = 39)% duty cycle (slow)
analogWrite (pwm_b, 50);
}

void loop ()
{
digitalWrite (dir_a, LOW); / / Set motor direction, a low, 2 high
digitalWrite (dir_b, LOW); / / Set motor direction, three high, four low
delay (1000);
analogWrite (pwm_a, 50); / / set both motors to run at 100% duty cycle (fast)
analogWrite (pwm_b, 50);
delay (1000);
digitalWrite (dir_a, HIGH); / / Reverse motor direction, one high, two low
digitalWrite (dir_b, HIGH); / / Reverse motor direction, three low, four high
delay (1000);
analogWrite (pwm_a, 100); / / set both motors to run at (100/255 = 39)% duty cycle
analogWrite (pwm_b, 100);
delay (1000);
}

What and where you want to change the library or where you can download right?
