New Features

Version 04.04.00

64-bit applications are now supported

General Changes

Version 04.04.00

	Firmware Pointer Changed to uint32_t
		Reference Number:
		Type: Change Feature
		MPI 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.

	MPI Function Changes
		Reference Number:
		Type: Change Feature
		MPI Version: 04.04.00
		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.

	Dual Compare
		Reference Number:
		Type: Change Feature
		MPI Version: 04.04.00
		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).

Fixed Bugs

Version 04.04.01

	mpiMapPtrToSymbol() Function Does Not Work With MPICapture.Data.State addresss
		Reference Number: MPI 2720
		Type: Fixed Bug
		MPI Version: 04.04.01
		Problem: Map: symbol not found is returned when setting the map pointer as MPICapture.Data.State address and calling the mpiMapPtrToSymbol() function.
		Cause: Improper coding of the mpiMapPtrToSymbol() function.
		Fix/Solution: The mpiMapPtrToSymbol() function was corrected.

Limitations

	Motion Console and Motion Scope Require Administer User Permissions
		Reference Number: N/A
		Type: Limitation
		MPI Version: 04.04.xx
		Description: If installed in the default installation directory (C:\Program files), Motion Console and Motion Scope require administrator privileges to run. This is due to increased security measures by Microsoft in Windows 7 and above. Installing to an alternate directory will circumvent this requirement.

	SimServer Still Under Development
		Reference Number: N/A
		Type: Limitation
		MPI Version: 04.04.xx
		Description: At the time of the release, the development of SimServer had not been completed. This feature is available as a standalone package and is not included in the MPI distributables.

	MechaWare Still Under Development for 64-bit Applications
		Reference Number: N/A
		Type: Limitation
		MPI Version: 04.04.xx
		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.
