Error with MATLAB Adafruit Breakout SPI

Hi,

I am trying to use the following library: https://www.mathworks.com/matlabcentral/fileexchange/48248-ftdi-spi-library-access. I changed the code a little bit so that it would show warnings and it showed this one: 'libMPSSE_spi_matlabFriendly.h libMPSSE_thunk_pcwin64.c Creating library libMPSSE_thunk_pcwin64.lib and object libMPSSE_thunk_pcwin64.exp ' Does anyone know what this means? The software says that it is not reading the Adafruit. I am not sure what is going on.

Thanks, Sarah C.

That message would likely be generated by loadlibrary(). When you pass loadlibrary() a DLL and a .h header file, then creates a thunk file and saves it, and after that you can improve performance of loadlibrary() by referring to the thunk file.

Thanks :-). I also figured out why MATLAB wasn't recognizing the chip. I needed to install another driver along with the LibMPSSE-Driver called D2XX. However, now it is not writing to GPIO pins properly.
