Nusbio GPIO API

Overview

Nubsio is a Windows plug and play USB interface to connect your PC to the external world and control electronic devices with any .NET languages.

Nusbio offers:

• 8 digital Input/Output pins (or GPIO) with support of the SPI and I2C protocols
• 8 analog to digital pins (ADC, with the Analog or Sensor extension) 

programmable in any .NET languages

GPIO API

PinMode 

By default the GPIO pins are initialized as output. To change the direction of an GPIO pin, use the following methods from the Nusbio class.

public void SetPinMode(NusbioGpio pin, PinMode mode);
public void SetPinMode(int pin, PinMode mode);

// Sample 

var serialNumber = Nusbio.Detect();
using (var nusbio = new Nusbio(serialNumber: serialNumber))
{
    nusbio.SetPinMode(NusbioGpio.Gpio0, PinMode.Output); // Enum type syntax
    nusbio.SetPinMode(1, PinMode.InputPullUp); // Integer syntax
}

 
The nusbio.GPIOS property allow to access the 8 GPIO pins using the following interface.

public interface GpioPublicApiBase
{
    PinMode Mode { get; }
    string Name { get; }
    PinState PinState { get; }
    bool State { get; set; }

    PinState DigitalRead();
    void DigitalWrite(PinState on);
    void DigitalWrite(bool high);
    void High();
    void Low();
}

// Sample

var serialNumber = Nusbio.Detect();
using (var nusbio = new Nusbio(serialNumber: serialNumber))
{
    nusbio.SetPinMode(NusbioGpio.Gpio0, PinMode.Output); // Enum type syntax
    nusbio.SetPinMode(1, PinMode.InputPullUp); // Integer syntax

    // Turn gpio pin 0 on
    nusbio.GPIOS[NusbioGpio.Gpio0].DigitalWrite(PinState.High);
    nusbio.GPIOS[NusbioGpio.Gpio0].DigitalWrite(true);

    // Read the state for gpio 1
    var state = nusbio[1].DigitalRead();
    state = nusbio[1].DigitalReadDebounced();
}
