can not import FTDI libMPSSE dll

[Pappion]

Need to import libMPSSE_i2c.h, W32 libMPSSE.dll.

"The following symbols are not defined:FT_STATUS; "

I don't have enough "C" experience to understand the failure.

Import wizard might be ignoring 2nd .h file.

Make sure that the ft2dxx.h header is somewhere the import wizard can find it. Screenshots showing how you set up the import wizard would help us help you, too.

Fixed it.

Defined FT_STATUS in 1st header file.

Second header defined it as ulong and enum.

 Hello Pappion!

I read in the NI forums that you solved the define problems in LibMPSSE. I was wondering what the exact measures you took were?

[Pappion]

That will have to wait until I get back Monday

Thanks Pappion,

I took a look at the DLL and realized What I needed to do was Define FT_STATUS in the preprocessor. I felt kind of silly not being able to figure out. I'm going back to figure out how to get getChannelInfo() to be recognized! I guess thats the question I have now, I'm going to go back to the defines in the header and see if I need to do anything to get it recognized. Thanks again.

I just checked libMPSSE_i2C.h and under Type Defines I added:

typedef uint32 FT_STATUS;

I did not bother with getChannelInfo() and just have i disabled. Something about getting on with real work vs curiosity.

Did you solve it?

Hi,

I connect 4232h mini module to laptop and run the test.vi from the 282mpseedll- labview-driver and it not work.

To the I2C channel 0 i connect IC P/N:TCA9555 and his address 41h.

i get error of device not found or param missing.

The some VIS operate ok like openchannel or getinfo .

i am using labview 2009 sp1 32 bit.

i try it also in labview 2016 32 bit.

why the function of initchannel fail?

i put right device address and for write i select option start and stop.

when i complie the example code in c (libMPSSE_source) it operate ok.

PLS advise.

BR,

Ilan
