# Wiring Pi Software PWM
Dart implementation of the Wiring Pi Software PWM library.
I mainly created this package for one of my own projects, so I haven't done a lot of testing yet. But I still hope this makes the creation of your flutter-pi app (or whatever you create) easier.
## Installing Wiring Pi
Visit this [guide](http://wiringpi.com/download-and-install/) to install the Wiring Pi library on your Raspberry Pi. If your are using a Raspberry Pi 4B you might also check this [post](http://wiringpi.com/wiringpi-updated-to-2-52-for-the-raspberry-pi-4b/).
The library (`.so` file) should be located under `/usr/lib/libwiringPi.so`.
## Using the package
First create the `SoftPwmGpio`. It takes the the pin of the GPIO. Afterwards call the `setup` method.
```dart
final pwmGpio = SoftPwmGpio(12);
pwmGpio.setup();
```
The `SoftPwmGpio` is now setup and ready to use. You can use the `write` method to set the PWM duty cycle. The method only allows values between 0 and 100.
```dart
pwmGpio.write(50);
```
