urgent help - splitting a string into 5 u8 data

[Mathan]

Hai mike,

Thanks.

But my dll has only one input (U8) terminal. So i have to pass the data one by one. That's why i asked how to send all those 5 one by one.

Thanks & Regards,

Mathan

Hi mathan,

can show your dll call? I mean the function call. Maybe it is possible to send the entire array at once.

Hai mike,

Sorry for the late reply. I have attached the screenshot of my code.

The second Call Library Node has 5 inputs and 2 outputs(responses). The fifth input that should be a U8, requires the following inputs 20H, 10H, 01H, 01H, 00H.

Thanks & Regards,

Mathan

Hi mathan,

do you have to set this value one after the other? Did you write this dll? Where is the dll from? Sorry, but i´m not sure what you want to do.

Dear mike,

Actually am testing my USB device. That device can be controlled with one dll that was already developed by the manufacturers of that device. I know the built in functions of the device.

Am not clear as of now. i will recollect everything and explain you tomorrow. Sorry

Thanks,

Dear mike,

Am attaching here the vi and the dll. Please go through it.

I got the error message that i also attached.

The problem is with the declaration of 'command' and 'response' parameters.

Command parameter: It should get this as input (2010010100 H) as a whole.

Response parameter: Its an output parameter that will have some stored output results in hexadecimal values like this 3b 6d 00 00 00 4f 84 24 fc 00 34 7a cb 65 ba 12 ff 90 00

Kindly modify the vi and reply asap.

Thanks,

Mathan

Hi mathan,

that´s interesting, on my pc it works, but i don´t know what your dll makes so it is possible that it work for my, because i have no hardware and for you not.
