Wiring Pi Serial

Dart implementation of the Wiring Pi serial 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 to install the Wiring Pi library on your Raspberry Pi. If your are using a Raspberry Pi 4B you might also check this post.

The library (.so file) should be located under /usr/lib/libwiringPi.so.

Using the package

The first thing todo is to create the SerialDevice. It takes the path to the device (default: /dev/serial0) and the baud rate of the connection (default: 9600). Afterwards call the setup method.

final serialDevice = SerialDevice();
serialDevice.setup();

The SerialDevice is now setup and ready to use. You can use all the commands mentioned in the Wiring Pi documentation, except the serialPrintf method.

device.sendByte(0x69);
device.sendString("Hello Serial Device!");
final values = device.getValues();
for (int i = 0; i < values.length; i++) {
    print("Value at $i: ${values[i]}");
}
device.closePort();

If any of the methods fails a SerialException will be throwen.
