Re: Creating VISAResource name in LABView using call library function
Dear Sir,The existing Instrument driver which I am talking about is a driver template provided by emcware software(by AR). These templates can be customized by adding instrument specific SCPI...

Probably your function call is wrong. Perhaps you need stdcall in stead of c calling convention? Can't open your VI, still at LV18...
View ArticleRe: Using FFT PT BY PT
You're creating an array of points, in sine shape. Than, you pass one of those points to the FFT PtByPt. It never gets to see the sine, only the first point of it! So, put the FFT PtByPt in a for loop,...

All other functions are on stdcall, the write is on c.. Or did you just change that on my advice? If all other functions work, the write should be stdcall too.

Bytes written should be a pointer to the value. An input can never return a value unless it's a pointer!

You're passing an array of I32s to the dll, which accepts an array of I16s. I don't know what it should be, but it's suspicious.

Within the call library function the buffer is defined as an array pointer, so I'm not sure what you mean.

View ArticleRe: 3D representation problems with some new graphical cards
The 3D graph is based on OpenGL and LabVIEW uses an OpenGL driver probably derived from an Open Source project. It’s perfectly imaginable that they regularly synchronize their version with the Open...
