TMS320VC5402 DSK BLINK EXAMPLE (USING DSP/BIOS) =============================================== The DSP/BIOS blink example demonstrates a few of the TMS320C5402 DSK and DSP/BIOS features with Code Composer Studio. Note that this example was run with external SRAM activated. The blink example demonstrates the use of the three (3) user LEDs on the DSK board. This simple blinking example continuously blinks all the three LEDs sequentially on the board with a second delay between blinks. Getting Started =============== The following instructions enable you to build and run the blink example. You do not have to create and build a project. If you prefer to see a quick demo, you can open CCS and load the file c:\ti\c5400\dsk\examples\dsp\blink_bios\blink_bios.out. 1.1 Creating a New Project =========================== 1) If you installed Code Composer Studio in c:\ti, create a folder called "blink_bios" in the c:\ti\myprojects folder. (If you installed else- where, create a folder within the myprojects folder in the location where you installed.) 2) Copy two source files from the c:\ti\c5400\dsk\examples\dsp\ blink_bios\{blink_b.c, blink_bioscfg.cmd} folder to this new folder 3) Copy two library files to your new folder. The library files are in the c:\ti\c5400\dsk\lib\{drv5402.lib,dsk5402.lib} folder. 4) From the Windows Start menu, choose Programs->Code Composer Studio 'C5000->CCStudio. (Or, double-click the Code Composer Studio icon on your desktop.) Note: Code Composer Studio Setup If you get an error message the first time you try to start Code Composer Studio, make sure you run Code Composer Setup after installing Code Composer Studio following the Quick Start Guide. 5) Choose the Project->New menu item. 6) In the Save New Project As window, select the working folder you created and click Open. Type "blink_bios" as the filename and click Save. Code Composer Studio creates a project file called blink_bios.mak. This file stores your project settings and references the various files used by your project. 1.2 Adding Files to a Project ============================= 1) Choose Project->Add Files to Project. Select blink_b.c and click Open. 2) Choose Project->Add Files to Project. Select Linker Command File (*.cmd) in the Files of type box. Select blink_bioscfg.cmd and click Open. This file maps sections to memory. 3) Choose Project->Add Files to Project. Select Object and Library Files (*.o*, *.lib) in the files of type box. Select drv5402.lib and click Open. Repeat this procedure for dsk5402.lib. 4) Choose Project->Add Files to Project. Select Configuration Files (*.cdb) in the files of type box. Select blink_bios.cdb and click Open. 5) Expand the Project list by clicking the + signs next to Project, blink_bios.mak, Libraries, and Source. This list is called the Project View. Note: Opening Project View If you do not see the Project View, choose View->Project. Click the File icon at the bottom of the Project View if the Bookmarks icon is selected. 1.3 Changing Project Build Options ================================== 1) Choose Project->Options. Click the Compiler Tab in the Include Search Path. Type in c:\ti\c5400\dsk\include. Click 'OK'. This will enable the appropriate board.h and type.h files to be included. When building the program, Code Composer Studio finds files by searching for project files in the following path order: o The folder that contains the source file. o The folders listed in the Include Search Path for the compiler or assembler options (from left to right). o The folders listed in the definitions of the C54X_C_DIR (compiler) and C54X_A_DIR (assembler) environment variables (from left to right). The C54X_C_DIR environment variable defined by the installation points to the folder that contains the rts.lib file. 1.4 Reviewing the Code ====================== 1) Double-click on the Blink_b.c file in the Project View. You see the source code in the right half of the window. 2) You may want to make the window larger so that you can see more of the source code at once. You can also choose a smaller font for this window by choosing Option->Font. 1.5 Building and Running the Program ==================================== Code Composer Studio automatically saves changes to the project setup as you make them. In case you exited from Code Composer Studio after the previous section, you can return to the point where you stopped working by restarting Code Composer Studio and using Project->Open. To build and run the program, follow these steps: 1) Choose Project->Rebuild All or click the (Rebuild All) toolbar button. Code Composer Studio recompiles, reassembles, and relinks all the files in the project. Messages about this process are shown in a frame at the bottom of the window. 2) Choose File->Load Program. Select the program you just rebuilt, blink_bios.out, and click Open. (It should be in the c:\ti\myprojects\blink_bios folder unless you installed Code Composer Studio elsewhere.) Code Composer Studio loads the program onto the target DSP and opens a Dis-Assembly window that shows the disassembled instructions that make up the program. (Notice that Code Composer Studio also automatically opens a tabbed area at the bottom of the window to show output the program sends to stdout.) 3) Click on an assembly instruction in the Dis-Assembly window. (Click on the actual instruction, not the address of the instruction or the fields passed to the instruction.) Press the F1 key. Code Composer Studio searches for help on that instruction. This is a good way to get help on an unfamiliar assembly instruction. 4) Choose Debug->Run or click the (Run) toolbar button. Analyze results (see below). 5) Choose Debug->Halt or click the (Halt) toolbar button to end the program. 1.6 Expected Results ==================== Running your program should result in all three LEDs on the board blinking continuously in sequential order.
