MFC工控项目实例二十手动测试界面模拟量输入实时显示

根据板卡设置界面组合框选项设定的AD输入信号，通过读取文件中保存的键值，用定时器实时显示模拟量输入数值。

1、在Data_1.h文件中添加代码

cpp 复制代码

CString COMB_Data_AD_1[]={"AD输入1","AD输入2","AD输入3","AD输入4","AD输入5","AD输入6","AD输入7","AD输入8","AD输入9","AD输入10","AD输入11","AD输入12","AD输入13","AD输入14","AD输入15","AD输入16"};
int COMB_Data_AD_Number_1;
unsigned char b_AD_1[16];
CString b_str_AD_1[16];
unsigned short AD_1[16];

2、在JogTest.cpp中添加代码

cpp 复制代码

BOOL CJogTest::OnInitDialog() 
{
	CDialog::OnInitDialog();
	...
		for( i=0;i<=COMB_Data_AD_Number_1;i++)
   {
	   
	 GetPrivateProfileString("AD输入",COMB_Data_AD_1[i],NULL,b_str_AD_1[i].GetBuffer(20),20,strFilePath);	
     AD_1[i]=_ttoi(b_str_AD_1[i]);
	}
	SetTimer(1,500,NULL);
	...
}


void CJogTest::OnTimer(UINT nIDEvent) 
{
if( nIDEvent == 1 )
	{
		//16通道，2 = -5000 -- 5000 mV采集
        AI6325AAllSingle(nAddr_AD_1, 2, m_saveData_AD_1);
		CString tempStr;
		CString str[30];
		tempStr.Format("%d",m_saveData_AD_1[AD_1[0]]);
	
		for ( int i=0 ; i<4 ; i++)
	{		  
			GetDlgItem(m_nCounterID[i])->SetFont(&m_font);
            str[i]=tempStr.Mid(i,1);
		    SetDlgItemText(m_nCounterID[i],str[i]);
		  
	}
	
	}
	CDialog::OnTimer(nIDEvent);

}
