I have a MCC USB-205 DAQ, the speed of it is very less because it doesnt support foreground and background operations. I thought of writing an MEX file to increase the speed of it. I downloaded the code from https://in.mathworks.com/matlabcentral/fileexchange/31989-sending-digital-codes-with-measurement-computing-boards-with-mex but i get the following errors,
>>mex digCode.c
Building with 'MinGW64 Compiler (C)'.

Can anyone help me with it. Where can i find supporting documents to write mex file for mcc daq.
