VISA是一种用来与各种仪器总线进行通信的高级应用编程接口,可用来对USB、GPIB、串口、VXI、PXI和以太网系统进行配置、编程和调试
下面是一些资料:
1.NI-VISATM Programmer Reference Manual
2.NI-VISA™ User Manual
原版rsVISA用到的dll和h头文件
简单的封装了下, 完整库代码和调用示例, 请看楼下8楼.

这里的示例都是使用的RSVisa.dll, RS和NI只是一点点区别, 实际上都是用的ivi的visa.lib进行的封装, 文档可以完全相互参考.
RS提供的visa测试软件功能更简洁,而且可以显示每一步所使用的代码, 更方便调试.
从测试软件里可以得到很多信息, 这些代码都是我们今后需要在程序里调用的, 具体的参数功能还是需要看看文档了解下.
我下面弄个动态图, 具体来演示下:
从图上可知: 我最后读取到的波特率和设置波特率的代码应该如下:
mainForm.button3.oncommand = function(id,event){
console.log( "viGetAttribute,BAUD 设置前:",viGetAttribute(instr,0x3FFF0021/*VI_ATTR_ASRL_BAUD*/,0) )
status = viSetAttribute(instr, 0x3FFF0021/*VI_ATTR_ASRL_BAUD*/, 115200);
console.log( "viGetAttribute,BAUD 设置后:",viGetAttribute(instr,0x3FFF0021/*VI_ATTR_ASRL_BAUD*/,0) )
}
上面aardio的代码和列表里显示的一模一样.

增加几个常用函数
2021-09-09 14:22 更新:
修正dll函数中几处错误
研究visa发现, 其实很多时候并不需要那么多的函数来使用, 为了对aardio中使用更友好, 我在RS官方示例基础上, 对dll进行了二次封装, 只保留了9个函数.
VisaRsrc VisaGetRsrcString VisaInit VisaClose VisaSetAttr VisaGetAttr VisaWrite VisaRead VisaClear
VISADllEx.dll 下载:
VISADllEx的vs2015工程源码下载:
这里我用串口进行了visa的模拟,
特别注意: 串口初始化完成, 默认波特率是9600 , 8,0,0,1 , 接收中断默认是接收到'\n'即"0x0A"字符, 如果你的设备不是默认配置, 那么就使用 VisaSetAttr() 对设备进行属性设置, 改变波特率和结束符符号.
至于属性是哪个, 可以参考楼上的方式找到.
aardio中调用示例如下:
import win.ui;
/*DSG{{*/
mainForm = win.form(text="dlltest";right=446;bottom=259)
mainForm.add(
button={cls="button";text="write";left=26;top=84;right=278;bottom=148;z=1};
button2={cls="button";text="read";left=26;top=171;right=278;bottom=235;z=2};
button3={cls="button";text="VisaGetAttr";left=298;top=84;right=429;bottom=148;z=4};
button4={cls="button";text="VisaClear";left=298;top=168;right=429;bottom=232;z=5};
edit={cls="edit";text="*IDN?";left=26;top=34;right=278;bottom=69;edge=1;z=3}
)
/*}}*/
import console
console.open()
var dll = ..raw.loadDll("\res\VISADllEx.dll","VISADllEx");
VisaRsrc = dll.api("VisaRsrc","int()" );
VisaGetRsrcString = dll.api("VisaGetRsrcString","string(INT)" );
VisaInit = dll.api("VisaInit","bool(string)" );
VisaClose = dll.api("VisaClose","bool()" );
VisaWrite = dll.api("VisaWrite","bool(string)" );
VisaRead = dll.api("VisaRead","string(WORD)" );
VisaSetAttr = dll.api("VisaSetAttr","bool(INT,INT)" );
VisaGetAttr = dll.api("VisaGetAttr","INT(INT)" );
VisaClear = dll.api("VisaClear","bool()" );
var count = VisaRsrc();
console.log( count )
for(i=0;count-1;1){
console.dump( VisaGetRsrcString(i) )
}
console.log(VisaInit("ASRL1::INSTR"))
mainForm.button.oncommand = function(id,event){
console.log(VisaWrite(mainForm.edit.text))
}
mainForm.button2.oncommand = function(id,event){
//0=默认读取1024个数据, 其他数字为读取数量
console.log(VisaRead(0))
}
mainForm.onClose = function(hwnd,message,wParam,lParam){
VisaClose()
}
mainForm.button3.oncommand = function(id,event){
console.log( VisaGetAttr(0x3FFF0021/*VI_ATTR_ASRL_BAUD*/) )
}
mainForm.button4.oncommand = function(id,event){
VisaClear();
}
mainForm.show();
return win.loopMessage();
试过USB通讯可以通讯，可以增加一个查询可用端口的函数就更好了。
visa在labview中连续使用的时候, 一般是这样
红色部分是获取串口缓冲池中有多少个数据字节数, 将这个字节数给读取函数 , 意思就是将缓冲池中所有的数据读出来.
那么代码中要用
#define VI_ATTR_ASRL_AVAIL_NUM (0x3FFF00ACUL)
这个属性来获取缓冲池内数据字节数.
var num = VisaGetAttr(0x3FFF00AC); var retStr = VisaRead(num);
顺便说下, visa有个不是bug的bug , 一直未改善
设置接收中断字节 和 中断使能功能的bug
当你使用下面二个属性想要设置 不使用 中断字节码
#define VI_ATTR_TERMCHAR (0x3FFF0018UL)
#define VI_ATTR_TERMCHAR_EN (0x3FFF0038UL)
你必须也要设置这个属性
#define VI_ATTR_ASRL_END_IN (0x3FFF00B3UL)
它们三个配合使用才能取消中断字节码的中断功能.......
status = viSetAttribute(instr, 0x3FFF0018, 0x0a); status = viSetAttribute(instr, 0x3FFF0038, 0); status = viSetAttribute(instr, 0x3FFF00B3, 0);
封装了个简单的库 , 下面是库代码和调用示例:

var count = VisaFindRsrc();
if(count!=0){
for(i=0;count-1;1){
var str = VisaGetRsrcString(i);
..table.push(stringList,str);
}
return stringList;
}
return null;
};
open = function(deviceName){
return VisaInit(deviceName);
};
writeString = function(str){
return VisaWrite(str);
};
readString = function(len){
if(len!=null){
return VisaRead(len);
}
return VisaRead(0);
};
setAttr = function(k,v){
return VisaSetAttr(k,v);
};
getAttr = function(k){
return VisaGetAttr(k);
};
close = function(){
VisaClose();
};
}
namespace VISADllEx{
_dll = ..raw.loadDll($"\res\VISADllEx.dll");
