How can I load the DLL from MCP2210 into Matlab?

Dear all?

I'm trying to load the MCP2210 dll provided by Microchip into Matlab. As instructed by a previous thread I used the following command:

asb = NET.addAssembly(fullfile(pwd,'MCP2210DLL-M.dll'))

to which I've got the following message:

"??? Message: Could not load file or assembly
'file:///C:\Users\Dina\Downloads\MCP2210_DLL_20130416\Managed\MCP2210DLL-M.dll' or
one of its dependencies. Operation is not supported. (Exception from HRESULT:
0x80131515)
Source: mscorlib
HelpLink:"

The DLL was in the working folder!

Please kindly advise!!!!

Regard!

we solved the same problem using the 32-bit version of Matlab.

Currently, we are able to use the different functions of the dll except for TxferSpiData function.

TxFerSpiData correctly performs the transmission (the return value is zero as indicate in the guide http://ww1.microchip.com/downloads/en/DeviceDoc/MCP2210DLL_2014-08-27.zip) but it does not change the value on the RxData.

Was someone able to correctly use TxFerSpiData?

Any suggestion would be appreciate.
