In many circumstances, it will help you select the most suitable code for your programs and improve the overall performance of your applications. 1.4.2 ST Assembly Chain for the ST7 Family The ST Assembly Chain is a cross development system for ST7-driven applications. It includes an assembler, a linker, a formatter and a librarian. The information flow is summarized in the chart below: YOUR SOURCE CODE IN ASSEMBLER .inc Librarian .asm .lib Assembler .err .lst .obj Linker .cod .sym .grp .map Formatter .s19 Simulator/Debugger EPROM Programmer 6/17 20 ST7MDTX-KIT 2 METHOD OF OPERATION 2.1 SOFTWARE INSTALLATION To install and setup the Starter Kit software, follow these steps: 1 Insert the delivery CD-ROM into your CD-ROM drive. 2 Using Windows Explorer, open the root directory of your CDROM drive. IF... Acrobat Reader is already installed on your system. Acrobat Reader is not yet installed on your system. THEN... Double-Click WELCOME.pdf. When the Welcome screen is displayed, click FREEWARE 1. Open the folder /PROGRAM/ACROBAT3 2. Select and install the approriate language version of Acrobat (for more details refer to the readme.txt in the CDROM root directory) 3. When Acrobat is installed, double-click WELCOME.pdf. When the Welcome screen is displayed, click FREEWARE Click here 7/17 21 ST7MDTX-KIT The ST7 Tool Chain Setup introductory window appears on your screen, referring to the three software components of the Starter Kit: - WGDB7 Debugger - ST Assembly Chain for the ST7 Family - ST7 Epromer Click Next to continue. 3 In the next window, Choose Destination Location, you will specify the folder (or directory) where to copy the whole Starter Kit software. Use the default folder (or directory) or choose another folder (or directory): Click here to select another path This is the default path Return to previous window Abort installation process Continue installation process Click Next to continue. 8/17 22 ST7MDTX-KIT 4 In the next window, Select Components, you will select the software components that are to be copied from the CD-ROM into the folder (directory) you specified before: To select a component, check the appropriate box Selecting the WGDB7 Debugger cause these subcomponents to be displayed When WGDB7 is selected, this line is always highlighted Option applicable only to emulation-aided debugging (not supported in this version of the Starter Kit) Return to previous window Abort installation process Continue installation process Click Next to continue. 5 The next window, Check Setup Information, displays the settings you have specified: - Destination folder (directory) - Components to be installed Click Next to confirm. Click Back to change any settings. 6 The copying process takes place. A progress indicator keeps you informed of the status of the operation. When the copying process terminates, and if you didn't select the ST Assembly Chain as a component to be installed, you are directed to the Setup Complete window (see further on). If you selected the ST Assembly Chain, you are prompted to modify your AUTOEXEC.BAT file (or your system registry). 9/17 23 ST7MDTX-KIT These changes affect: - the PATH option, where the path for the components of the Assembly Chain should be added, - the METAI and DOS4G environment variables that have to be set to the following values, respectively: SET METAI=C:\ By checking the appropriate box, you may display a Release Note for the WGDB7 Debugger, Version 2.0, and/or start a debugging session, immediately after the installation is completed. 10/17 24 ST7MDTX-KIT 2.2 USING THE ST ASSEMBLY CHAIN The ST Assembly Chain components are installed in a subdirectory of the installation root directory, named asm. By default, you will find all the software development tools that constitute the ST Assembly Chain in: C:\St7tools\asm For more information on how to develop applications or programs for the ST7 microcontroller, refer to the Software Tools for the ST7 Family User Manual included in the CD-ROM. 2.3 STARTING THE WGDB7 DEBUGGER The WGDB7 debugger is installed in the installation root directory. By default, you will find it in: C:\St7tools To start WGDB7, just click the corresponding icon (or name in the cascading menus) in the Windows desktop. The WGDB7 Introductory window appears: You will notice that this is the simulation-aided version of the debugger in which the behaviour of your program is just simulated, using a special software, as if it were running on an actual microcontroller. To debug it, you don't need any external hardware. The debugging session starts a few seconds later. To get accustomed to the product, you may start one of the sample programs provided with the package, via the File/Open debugger menu chain. The sample programs can be found in: C:\ 11/17 25 ST7MDTX-KIT 2.4 PROGRAMMING ST7 DEVICES 2.4.1 Target Devices Once bug-free and ready for operation, the program you just developed needs to be transferred into an ST7 MCU program space. With the ST7 MDT1 Starter Kit, you may program these MCUs(*): ST72101G1 or G2 ST72212G2 ST72213G1 ST72251G1 or G2 With the ST7 MDT2 Starter Kit, you may program these MCUs (*): ST72121J2 or J4 ST72311J2 or J4 ST72311N2 or N4 ST72331J2 or J4 ST72331N2 or N4 With the ST7 MDT4 Starter Kit, you may program these MCUs (*): ST72272K2 or K4 ST72372J4 ST72371N4 ST72671N4 or N6 (*) These lists are subject to modifications 2.4.2 Board and Device Setting Up Proceed as follows: 1 Place the device into the Zero Insertion Force (ZIF) socket mounted on the board. CAUTION. Ensure correct device orientation when plugging it into the ZIF socket. Incorrect insertion may damage the device and/or the board. 2 Using the parallel interface cable, connect the parallel port of the PC (LPT1 or LPT2) to the board connector (PI). 3 Power on the PC and the board. The board power LED (LD1) lights up. 12/17 26 ST7MDTX-KIT Notes The parallel port of your PC should have been configured as a Centronics parallel port. The supplied interface cable has been tested in order to operate properly on most PCs. Do not use any other cable, especially if it is longer than the one provided by STMicroelectronics: the board may not operate properly. The cable should be connected directly to the DB-25 female connector of the PC parallel port. This connector is similar to the one installed on the board. Do not insert any additional cables or switchboxes between the PC and the board: a malfunctioning of the board may result. If a dongle is mounted on the PC parallel port, it should not interfere with the programming board. Should you notice a dysfunctioning of the board, remove the dongle and restart the installation procedure. 2.4.3 Starting the Windows Epromer The Windows Epromer (Winee) is installed in the installation root directory. By default, you will find it in: C:\St7tools\Epromer To start the Windows Epromer, just click the corresponding icon (or name in the cascading menus) in the Windows desktop. The Epromer main window appears: Click here to display the epromer configuration window Note that as long as the programming board and the device to be programmed are not specified, the display area is blank. 13/17 27 ST7MDTX-KIT 2.4.4 Configuring the Epromer Follow these steps: 1 In the main window tool bar, click the dow: icon to select the epromer configuration win- 2 In the list, select the programming board for the Starter Kit: ST7MDT1-KIT, ST7MDT2-KIT or ST7MDT4-KIT, 3 Click the Select Chip tab to display the list of the devices that can be programmed with this Starter Kit. 14/17 28 ST7MDTX-KIT A list box similar to the one shown below appears. 4 In the list, select the device to be programmed. Click OK to confirm. The list box closes. The memory mapping of the specified device now appears in the display area of the main window. It is made up of "FFs", as one may expect, since programming has not taken place yet. 15/17 29 ST7MDTX-KIT To view in turn the memory mapping of a selection of devices plugged in, open the configuration window again, then the Select Chip list box, and click Apply. The display area of the main window changes while the list box stays open, for you to choose another chip if necessary. The name of the device to be programmed is displayed here Display area Details stored in the Epromer buffer for the space corresponding to the currently selected tab The EPROM has been selected Information area Progress bar Pppppp (progress of the current task being executed by the Epromer) Cursor position in the display area Origin of the display area contents 5 Start your programming session. For more information on how to use the Windows Epromer, click the Help command in the main menu bar. 16/17 30 ST7MDTX-KIT Notes: Information furnished is believed to be accurate and reliable.
