Summary

This extension supports the Motor drivers in micro:bit MakeCode programming.
Many motor driver ICs or their breakouts, including Kitronik motor driver board, can use the extension.
Motor command values can be positive or negative (-100..100) and they mean forward or backward.

Methods

Initialization (Always run at the beginning)
```
NiftyMotorDriver.initializeMotorDriver(motor: MotorEnum, pin1: DigitalPin, pin2: DigitalPin)
```
– Assigns micro:bit pins to the motor driver.
– The initialization can be omitted when using the Kitronik motor driver board-5620 / 5698. As well as the Kitronik Extension, the extension assigned pins P8, P12, P0, and P16 as default.
drive Motor
```
NiftyMotorDriver.driveMotor(motor: MotorEnum, sspeed: number)
```
– Set the speed value to the motor driver.
– The range of sspeed , that mans signed speeds, is -100 to 100.
– If the value is negative, the motor will reverse.
coast Motor
```
NiftyMotorDriver.coastMotor(motor: MotorEnum)
```
– Stop the motor.
– This is equivalent to “NiftyMotorDriver.driveMotor (MotorEnum.m1, 0)”.
brake Motor
```
NiftyMotorDriver.brakeMotor(motor: MotorEnum)
```
– Put the motor in the short brake state.

Example

NiftyMotorDriver.initializeMotorDriver(MotorEnum.m1, DigitalPin.P8, DigitalPin.P12)
basic.forever(function () {
    NiftyMotorDriver.driveMotor(MotorEnum.m1, 50)
    basic.pause(2000)
    NiftyMotorDriver.coastMotor(MotorEnum.m1)
    basic.pause(2000)
    NiftyMotorDriver.driveMotor(MotorEnum.m1, -50)
    basic.pause(2000)
    NiftyMotorDriver.brakeMotor(MotorEnum.m1)
    basic.pause(2000)
})
