C# UWP中的ABElecrtonics_Win10IOT_Libraries？

Question

有没有人能帮我理解一下如何用ABElecrtonics_Win10IOT_Libraries的C# UWP中的IoPiPlus扩展板来点亮led和读取按钮的状态？我找到的所有教程都是针对python的。谢谢。

Answer 1

The IO Pi Plus是一款32通道数字扩展板，专为覆盆子Pi设计。它可以通过树莓派I2C端口进行控制。GPIO #2，执行I2C。这是Raspberry Pi 2 & 3 Pin Mappings。

请参阅AB Electronics UK Windows 10 IOT库和演示。您可以将使能引脚设置为使用输出使能功能以及使能和禁用输出。

ABElectronics_Win10IOT_Libraries.ServoPi servo = new ABElectronics_Win10IOT_Libraries.ServoPi(0x40);

servo.OutputEnablePin = 17; // set to GPIO pin 17 to control
servo.OutputEnable();       //set Gpio Low
servo.OutputDisable();      //set Gpio High

Answer 2

同时，我设法用两个按钮控制了软件和硬件中的两个LED。下面我将放入代码，它可能会对其他人有用

using System.Threading;
using ABElectronics_Win10IOT_Libraries;
using Windows.UI.Popups;

namespace IoPiPlust_start_led
{
    public sealed partial class MainPage : Page
    {
        int x = 0;
        int y = 0;
        public IOPi bus1 = new IOPi(0x20);
        public IOPi bus2 = new IOPi(0x21);
        int TIME_INTERVAL_IN_MILLISECONDS = 100;
        Timer _timer1;

        public MainPage()
        {
            this.InitializeComponent();
            conect();
            _timer1 = new Timer(Timer1_Tick, null, TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite);
        }

        public async void conect()
        {
            bus1.Connected += Bus1_Connected;
            bus2.Connected += Bus2_Connected;
            await bus1.Connect();
            await bus2.Connect();
            bus2.SetPortDirection(0, 0x00);
            bus1.SetPortDirection(0, 0xFF);
            bus1.SetPortPullups(0, 0xFF);
            bus1.InvertPort(0, 0xFF);
        }

        private void Bus2_Connected(object sender, EventArgs e)
        {
            bus2.SetPortDirection(0, 0x00);
        }

        private void Bus1_Connected(object sender, EventArgs e)
        {
            ReadBus1();
            _timer1.Change(TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite);
        }

        private void Timer1_Tick(Object state)
        {
            if (bus1.IsConnected)

                    if (bus1.ReadPin(2))

                    if (!bus1.ReadPin(2))
                    { bus2.WritePin(2, false); }
                }
                _timer1.Change(TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite);
            }
        }

        public async void ReadBus1()
        {
            if (bus1.IsConnected)
            {
                try

                    {
                        bus1_pin1_chk.IsChecked = bus1.ReadPin(1);
                        bus1_pin2_chk.IsChecked = bus1.ReadPin(2);
                    }
                    );
                }
                catch (Exception e)
                {
                    throw e;
                }   
            }
        }

        private void red_led_btn_Click(object sender, RoutedEventArgs e)
        {

            if(x%2==0)
            { bus2.WritePin(2, true); }
            else
            { bus2.WritePin(2, false); }
            x++;
        }

        private void green_led_btn_Click(object sender, RoutedEventArgs e)

            if (y % 2 == 0)
