Ftdi MPSSE-I2C ou MPSSE-SPI lib with Visual Studio 2017 x86_64. Isn't a project, this is just a "HOW TO" to compile the libMPSSE-I2C from FTDI to use with Visual Studio x84_64.

Content

Due the mingw incompatibility with visual studio toolchain, is necessary a new compilation to provide useful libs for visual studio. The pre-compiled x86 libs are provided with the MPSSE lib, with version for visual studio x86 and mingw, but not the x86_64 version for visual studio. This tutorial demonstrate the use of lib.exe, a Visual Studio tool and dlltool.exe from mingw, to generate a compatible lib from the .def file generated by lib compilation with mingw64.

Compilling libMPSSE-I2C

1. Download the source code from ftdi site: LibMPSSE-I2C_source.zip

2. Download and Install mingw64 compiller and make.

3. Follow the instructions in file "...\LibMPSSE-I2C\Documents\BuildProcedure_LibMPSSE.txt". The ompiler will generate the .obj, .a and .def files inside the folder "...\LibMPSSE-I2C\LibMPSSE\Build\Windows\"

Generate .lib with lib.exe from Visual Studio

In Visual Studio command prompt go to libMPSSE folder and type:

lib.exe /MACHINE:X64 /DEF:libMPSSE.def

Generate .lib with dlltool.exe from mingw

Go to the to libMPSSE folder and type:

dlltool.exe -d libMPSSE.def -D libMPSSE.dll -l libMPSSE.lib

To use the files in Visual Studio

1. Copy the important project files, libMPSSE.dll, libMPSSE.lib from local folder, and the libMPSSE_i2c.h, WinTypes.h, ftd2xx.h from "...\LibMPSSE-I2C\Release\samples\I2C" folder to your Visual Studio's project folder.

2. The last step is change the line inside WinTypes.h:

#include <sys/time.h>

to

#include <time.h>

Considerations

• Some times lib.exe tool ignores some functions and do not exports to the .lib file, in this case use the dlltool.

• You can generate a complete lib I2C + SPI, fot this you need do add the SPI source folder in the Topllayer folder from libMPSSE and modify the makefile as this makefile.
