FTDI: Failing to load libMPSSE.dll

[githin]

Hi,

I am using the Labview environment to create the driver for MPSSE. Could please share the 64 bit version dll?

Thank you

On this page is the FTDI support for libMPSSE detailed: https://ftdichip.com/software-examples/mpsse-projects/libmpsse-spi-examples/

There you have the download for the latest version of that driver with source code, build files and binary artefacts of the 1.0.5 driver. https://ftdichip.com/wp-content/uploads/2024/08/LibMPSSE_1.0.5.zip

In this archive you have the DLLs for both win32 and x64 present too. The project files seems to be for Microsoft Visual Studio 2013 or newer, but the DLLs seem to be created in one of the latest Microsoft compilers so unless you try to use it on a prehistoric computer the according Visual Studio C Runtime library for sure should be present too.

You also will need to install the D2XX drivers from FTDI onto every computer you want to use the MPSSEE library on. This library implements the actual communication with the controller.

Hi,

Thank you for replying.

I tried using the DLL already present in the FTDI support page, but it doesn't seem to work. When I try the SPI_OpenChannel function, I get the error code 6 unknown status.

It's not clear who is returning error code 6. If it is the function call, error 6 means most likely FT_INVALID_PARAMETER.
