Release Note
MPI Library Version 04.04.00

Description:

The new firmware pointer ‘_MFWPTR_ (type)’ clearly distinguishes between 32-bit firmware pointer and 32-bit or 64-bit host pointer.

It is defined in MFPTR.H. MFWPTR.H is an additional header file to access 32-bit firmware from a 64-bit host. And the 64-bit host handles the 32-bit firmware pointer as 'uint32_t'. No changes have been made to the 32-bit host.

Related definitions:

MPI64: Identifies whether running a 64-bit OS or 32-bit OS. If it has been defined, it handles pointer of the firmware as ‘uint32_t’.

MPI_PLATFORM_WIN64: The identifier for Microsoft Windows7 64 bit.

Description:

A new argument '_MFWPTR_(type)' was added to support 32-bit firmware pointers on a 64-bit host. It is found in the following functions:

• mpiPlatformFirmwareAddress16To32
• mpiPlatformFirmwareAddress32To16
• mpiPlatformFirmwareAddress32To64
• mpiPlatformFirmwareAddress64To32
• mpiPlatformMemoryToFirmware
• mpiPlatformMemoryToHost
• mpiPlatformFirmwareAddressModify
• mpiPlatformFirmwareAddressModify16
• mpiPlatformFirmwareMemoryGet
• mpiPlatformFirmwareMemorySet

For more information see the Important Things to Know section.

Description:

The MPICompareConfig structure now includes an additional member ‘engineNumber’ to support multiple compare engines for a given motor. The default value should be set to ‘0’.

At this time, the AKD drive supports engineNumber 0 and 1 (aka dual compare).

Description:

At the time of the release, the development of MechaWare for 64-bit applications had not been completed. This feature is released as a standalone package and is not included in the MPI distributables. MechaWare is planned to be completed and supported in future releases.

Mechaware is available for 32-bit applications in the 04.03 release.
