function will be called once for each Cyclone.
8.2.3.4 Finalization
Before closing the application, it is recommended that the session with the PEmicro hardware be
terminated and the DLL unloaded from memory.
These calls should always be made before the application closes:
disconnectFromAllCyclones( );
unloadLibrary();
Note that the “unloadLibrary” call is only required for C/C++ applications. For the Delphi and C#
example projects, the DLL is automatically unloaded when the application closes.
8.2.3.5 Initial Cyclone Setup
The Cyclone Image Creation Utility software, which is included with each Cyclone, is used to
create the standalone images that will be stored in the non-volatile memory of the Cyclone. These
images contain the FLASH / EEPROM programming algorithms, the actual binary data to be
programmed, the sequence of programming operations, and user specified Cyclone settings.
Prior to using the Cyclone Control Suite, these standalone images need to be created. Please
refer to the user’s manual of your Cyclone unit for more information on standalone images and
image creation.
8.2.3.6 Typical Usage
Figure 8-1: Typical programming procedure flow chart
Figure 8-1 describes the most common sequence of calls to the DLL after successfully connecting
to the Cyclone unit.
a. Initiate programming operations. “startImageExecution” carries out the programming
operations defined in the stand-alone image stored on the Cyclone unit.
b. Wait for programming completion. Note that no error checking is provided by the
