Oops...I just saw that you said I would have to define the structure...

On the version of ps3000.h .dll and .lib I am using unitOpened2.handle gives the error that the var unitOpened2 is not defined.

I just rechecked everything. If you try to use unitOpened.handle2 = ps3000_open_unit it returns "structure has no member named 'handle2'. I haven't downloaded the source files since last fall. Perhaps that is the problem.

I tried that first and I still got an error. Perhaps I have something else wrong. Thanks for the advice.

To hook up multiple 3000 series oscopes, the manual says to use multiple handles, as was noted in topic below this one. The problem is the new canned driver design uses a new syntax, unitOpened.handle, instead of handle by itself. There is then a number it is assigned. The problem is running unitOpe...

MS Visual Express will compile .c extension files as C programs. Go ahead and use it. But, make sure you download the Software Development Kit (SDK) as well and follow the instructions to modify the appropriate files to activate all of the things you need to compile this software.

There is an error in the PS3000con.c driver (as of 8/6/2007) in the function set_defaults. The last argument of ps3000_set_channel is set to unitOpened.lastRange. This is wrong and will cause the data to be collected with the range set to the maximum upper voltage range (probably 20 V) instead of wh...

I answered my own question. Apparently c++ doesn't know what a BYTE variable is. I changed it to char and atleast the compiler doesnt complain. I'll report back if it actually works.

Has anyone successfully compiled PS3000con.c or PS3000.c with MS Visual C++ Studio 2005? I am getting all kinds of errors. Most stem from this section of code: typedef struct { short handle; MODEL_TYPE model; PS3000_RANGE firstRange; PS3000_RANGE lastRange; //BYTE signalGenerator; //BYTE external; s...

I have been using an older version of the provided Drivers on a 3205. I have been using PS3000con.c, slightly modified to trigger on the external trigger and read channels A and B. I compile on the standard Linux C compiler. Recently, I bought 8 more 3205's to ramp up my research and discovered that...
