Simple:
Add the Qt you just installed to the Qt version
Make a kit with it
Change the kit for your project
Build and run !

I have a new related problem. I get past all the code up to adding my data. I get junk in the pDataOut.
This should be an easy one right. Fingers crossed.@if (Res == 0) {
char *pDataOut = (char *)malloc(6);
char *pDataIn = (char *)malloc(6);for (int i=0; i<4; i++) { *(pDataOut+i) = ((i%2)==0) ? 0xAA : 0x00; *(pDataIn+i) = 0; } if (Res == 0) { printf("Adding macro Data32..."); Res = spis_ExecMacro("Data32", pDataOut+1, pDataIn+1); if (Res != 0) { printf("Macro Data32 failed!\n"); } else { printf("done\n"); } } delete pDataOut; delete pDataIn; }@
Here's the debug info

Why do you put data in pDataOut ? Shouldn't be in pDataIn ?
-
This is part of an example console program that worked as such. Maybe I should run that program in debug mode and see what it's sending. I'm sending data out of my PC to a SPI module which transfers these bits at 50MHz to a custom test fixture.
-
So pDataOut is what goes to the SPI module and pDataIn is what the module sends ?
Also, why the +1 ?
-
So pDataOut is what goes to the SPI module and pDataIn is what the module sends ? Yes, pDataIn reads back from the module.
Also, why the +1 ? I have no idea.
-
My intent is to send a 4 byte command.
-
It's getting strange, the 4byte command is stored in a 6byte array, the command start at 0 but you send starting at byte 1.
Sounds dubious...
-
Well I did clip a lot of the original code and just use what I thought I would need. I ran the console program without the +1s and changed the mallocs 2to 4. This seems to work great in the console program but again, not in the Qt5. Grrr.
@ if (Res == 0) {
char *pDataOut = (char *)malloc(4);
char *pDataIn = (char *)malloc(4);for (int i=0; i<4; i++) { *(pDataOut+i) = ((i%2)==0) ? 0xFA : 0x02; *(pDataIn+i) = 0; } if (Res == 0) { printf("Adding macro Data32..."); Res = spis_ExecMacro("Data32", pDataOut, pDataIn); if (Res != 0) { printf("failed!\n"); } else { printf("done\n"); }

If you are clipping too much code, you might be missing some initialization step or something
-
I don't have any errors but I can't get past this if statement so I'm not connecting through the DLL for some reason. Where is the disconnect from the button to the DLL? The code is the same and it should work. I've even added the conio and stdio include files. This is really strange.
@ int Res = 0;
int SpiHandle = spis_CreateInstance();
Res = spis_Connect("050112020E7", 3300);if (Res == 0) {@
-
Since you have that example that works fine, did you try to simply get the "whole" code from it and put it in a function that you would call in your program ?
Then you can try to clean it and remove what you don't need
-
I added the code to the main.cpp. Still doesn't open the console view. Seems like Qt5 doesn't want to open console programs.

I get this output when I run it. The serial number is fine, it must be getting scrambled somehow.
Starting DLL demo...Opening the SPI Storm library and retrieve handle...done
Serial Number failed!
Closing the SPI Storm library...done
Press any key...
The program has unexpectedly finished.

These parts might be the thing you are missing to get your data right. They seem to initialize something for the following calls and then put things back to normal.
