研华PCI1716L的C#编程

新建windows窗体项目；
添加引用研华的库文件

将库添加using

整个代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Automation.BDaq;
using System.IO;
namespace 研华1716L
{
    public partial class Form1 : Form
    {
        WaveformAiCtrl waveformAiCtrl = new WaveformAiCtrl();
        int getDataCount = 12000;
        short[] sectionBuffer=new short[12000];
        void waveformAiCtrl_DataReady(object sender, BfdAiEventArgs e)
        {
            waveformAiCtrl.GetData(getDataCount, sectionBuffer);
            StreamWriter sw = new StreamWriter("1.txt", true, Encoding.Default);
            for (int j = 0; j < 12000; j++)
            {
                sw.WriteLine(sectionBuffer[j]);
            }
            sw.Close();

        }
        public Form1()
        {
            InitializeComponent(); 
            string deviceDescription = "DemoDevice,BID#0";//根据设备改
            waveformAiCtrl.SelectedDevice = new DeviceInformation(deviceDescription);
            waveformAiCtrl.Prepare();
           
        }

        private void button1_Click(object sender, EventArgs e)
        {
            waveformAiCtrl.DataReady += new EventHandler<BfdAiEventArgs>(waveformAiCtrl_DataReady);
            waveformAiCtrl.Start();
        }

      
    }
}

实现简单功能点击按钮，将读的文件向TXT中写。原理性的就这些，整体的程序，放在代码仓库吧。

华研采集卡C#二次开发

1.安装驱动，研华DAQNavi软件开发工具包下载地址：线上服务 - 研华

安装之后可参考例程进行开发
 

还有开发手册

2.可添加华研采集卡控件

3代码添加控件

        private void InitializeComponent()
        {
            this.SuspendLayout();

           
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(274, 80);
            this.Name = "Form1";
            this.Text = "Form1";
            this.Load += new System.EventHandler(this.Form1_Load);
            this.ResumeLayout(false);
            // 
            // udCounterCtrl1
            // 
            this.components = new System.ComponentModel.Container();
            System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(UpDownCounterForm));
            this.udCounterCtrl1 = new Automation.BDaq.UdCounterCtrl(this.components);
            this.udCounterCtrl1._StateStream = ((Automation.BDaq.DeviceStateStreamer)(resources.GetObject("udCounterCtrl1._StateStream")));

        }

        #endregion
        private Automation.BDaq.UdCounterCtrl udCounterCtrl1;

4.C#对象创建instantDiCtrl.SelectedDevice = new DeviceInformation(“PCI-1750,BID#0”)，卡名称可在安装的驱动软件中找到，或者输入卡号，代码示例：

        public UpDownCounterForm(int deviceNumber)
        {
            InitializeComponent();
            udCounterCtrl1.SelectedDevice = new DeviceInformation(deviceNumber);
        }

        private void UpDownCounterForm_Load(object sender, EventArgs e)
        {   
            if (!udCounterCtrl1.Initialized)
            {
                MessageBox.Show("No device be selected or device open failed!", "UpDownCounter");
                this.Close();
                return;
            }

            //set the title
            this.Text = "UpDown Counter(" + udCounterCtrl1.SelectedDevice.Description + ")";
    
        }

5.其他可参考官方示例代码
