Program Execution Overview

The program begins execution in Onlnit in Hwmgrdlg.cpp. This bring up the wxWindows dialog interface that you see at the beginning of the program (see Figure 1).

Figure 1: wxWindows dialog interface

After the user enters the desired parameters into the dialog, the program then calls RunXDScope, which is located in xprog.cpp.

RunXDScope then initializes and creates the primary display window, and assigns the parameters entered in the HwMgr dialog interface to the DSP class. Then, the DSP Hardware Initialization begins. The board is assigned a board handle, and the board is reset. The DSP COFF file entered in the HwMgr dialog is downloaded to the DSP, the selected processors are reset, and all the variables needed to run the DSP are downloaded. The selected processors are run, and thus the data transfer loop begins. When the DSP signals that it is ready, a buffer of data is uploaded to the host PC, and the display is updated. After the user presses a key, the program breaks out of the data transfer loop and stops the DSP hardware. XDScope then closes down the main window and exits.
