4.2 Generic instructions

Generic instructions are related to initialization programmer process, configuration setup and

preparation data, turning ON and OFF target’s DC and RESET target device. Any communication

with the target device is provided when any of the generic instruction is executed. Generic

instructions should be called before encapsulated and sequential instruction.

F_Check_FPA_access

F_Check_FPA_access - Check available Flash Programming Adapter (USB-MSP430-FPA

or MSP-FET430UIF) connected to specified USB drivers (USB

driver index from 1 to 64)

VALID FPA index (DLL instance number) - ( 1 to 64 )

Important: It is not recommended to use this function. Function used only for compatible with

the old software. Use the F_OpenInstancesAndFPAs instead.

Do not use the F_OpenInstances or F_Check_FPA_access after using the

F_OpenInstancesAndFPAs. The F_OpenInstancesAndFPAs is assigning the FPAs to

USB ports and it is not recommended to reassign once again the USB port using the

F_Check_FPA_access function. To check the communication activity with FPA use the

F_Get_FPA_SN function that allows to check te communication with the FPA adapter

without modifying the USB ports assignment.

F_Check_FPA_access should be called as a first function when the *.dll is activated. Function

returns serial number of the detected flash programming adapter, or zero, if programming adapter

has not been detected with selected USB driver. Up to 64 USB drivers can be scanned.

To make a Multi-FPA software back compatible, the F_Check_FPA_access procedure is calling the

function F_OpenInstances if none of the instances has not been activated before. That allows to

use old application software without calling the new type of Multi-FPA functions.

Syntax:

MSPPRG_API LONG_X F_Check_FPA_access ( INT_X USB_index );

Parameters:

Index: USB driver index from 1 to MAX_USB_DEV_NUMBER

where MAX_USB_DEV_NUMBER = 64

To search ONLY the USB-MSP430-FPA adapters.

Index = Index | 0x100

To search the USB-MSP430-FPA and MSP-FET430UIF adapters.
