The selected FPA index modified by the F_Set_FPA_index( fpa ) instruction can be modified at any
time. By default, the FPA index is 1 and if only one FPA is used then fpa index does not need to be
initialized or modified. When the fpa index 1 to 16 is used, then the result is coming back to
application software from the single API-DLL via transparent Multi-FPA dll. When fpa index is 0
(ALL-FPAs) and results are the same from all FPAs, then the same result is passing back to
application software. If results are not the same, then the Multi-FPA dll is returning back value -1
(minus 1) and all recently received results can be read individually using function
F_LastStatus( fpa )
Most of the implemented functions allows to use the determined fpa index 1 to 16 or 0 (ALL-FPAs).
When functions return specific value back, like read data etc, then only determined FPA index can
be used ( fpa index from 1 to 16). When the fpa index is 0 (ALL-FPAs) then almost all functions are
executed simultaneously. Less critical functions are executed sequentially from FPA-1 up to FPA-16
but that process can not be seen from the application software.
When the inactive fpa index is selected, then return value from selected function is -2 (minus 2).
When all fpa has been selected (fpa index = 0) then only active FPAs will be serviced. For example
if only one FPA is active and fpa index=0, then only one FPA will be used. It is save to prepare the
universal application software that allows to remote control up to sixteen FPAs and on the startup
activate only desired number of FPAs.
It should be noticed, that all single API-DLLs used with the Multi-FPA DLL are fully independent
to each other. From that point of view it is not required that transferred data to one FPA should be
the same as the transferred data to the others FPAs. For example code data downloaded to FPA-1
can be different that the code data downloaded to the FPA-2, FPA-3 etc. But even in this case the
programming process can be done simultaneously. In this case the desired code should be read from
the code file and saved in the API-DLL-1, next code file data should be saved in the API-DLL-2 etc.
When it is done, then the F_AutoProgram can be executed simultaneously with selected all active
FPAs. All FPAs will be serviced by his own API-DLL and data packages saved in these dlls.
The following commands are supported in the DLL library:
Initialization and termination communication with the programming adapter,
Programmer configuration setup,
Programming report message,
Code data and password data read from the file,
Reset target device,
Auto program target device ( erase, blank check, program and verify),
CSM Password verification,
