1. Lecture 3 Code Composer Studio and the DSK6416

2. Learning Objectives • Introduction to Code Composer Studio (CCS). • Installation and setup of CCS. • Introduction to the DSK. • Laboratory.

3. Code Composer Studio • The Code Composer Studio (CCS) application provides an integrated environment with the following capabilities: • Integrated development environment with an editor, debugger, project manager, profiler, etc. • ‘C/C++’ compiler, assembly optimiser and linker (code generation tools). • Simulator. • Real-time operating system (DSP/BIOS™). • Real-Time Data Exchange (RTDX™) between the Host and Target. • Real-time analysis and data visualization.

4. CCS Installation and Setup (A) Insert CD and Install the CCS Software. (B) Connect DSK to Power and USB and Run CCS Setup (do not remove CD): • Start CCS setup utility by using the following desktop icon: • Alternatively: • Windows Start Menu -> Programs -> Texas Instruments -> Code Composer Studio 3.1 (‘C6000) -> Setup Code Composer Studio 3.1 • Run cc_setup.exe located in: c:\CCStudio_v3.1\cc\bin\

5. CCS Installation and Setup (C) After Installation you should see the following icons:

6. CCS Installation and Setup • You should now see a screen similar to this: Note: If you don’t see the Import Configuration dialog box you should open it from the menu using: File: Import.

7. CCS Installation and Setup • You can clear the previous configuration by selecting the configuration you wish to clear and clicking the clear button. • Next select a new configuration that you would like to add: • Select the C6416DSK Port x y Mode. • The port number, x, and port mode, y, depend on your PC setup.

8. CCS Installation and Setup • Finally save and quit the import configuration dialog box.

9. Testing Your Connection • If you want to test your DSK and USB connection you can launch the C6416 DSK Diagnostic Utility from the icon on your desktop. • From the diagnostic utility, press the start button to run the diagnostics. In approximately 30 seconds all the on-screen test indicators should turn green.

19. Communicate from Windows program (C++, VB) via parallel port using Win32 DLL CCS uses parallel port to control DSP via JTAG port You can use full TI eXtended Dev System (XDS) via 14 pin header connector Use HPI via Win32 DLL JTAG ....... ....... Software: (2) PC  DSK Communications DSP JTAG Emulation Port Note: You should not use the parallel port for simultaneous emulation and HPI connection.

20. Communicate from MATLAB (SIMULINK) CCS uses USB to control DSP via JTAG port You can use RTDX Use USB JTAG ....... ....... Software: (3) PC  DSK Communications DSP JTAG Emulation Port Note: Limited data rate up to 2MB/Sec.

21. Software: (4) PC  DSK Communications • Win32 API functions for Host to DSK communications: dsk6x_open( ) Open a connection to the DSK dsk6x_close( ) Close a connection to the DSK dsk6x_reset_board( ) Reset the entire DSK board dsk6x_reset_dsp( ) Reset only the DSP on the DSK dsk6x_coff_load( ) Load a COFF image to DSP memory dsk6x_hpi_open( ) Open the HPI for the DSP dsk6x_hpi_close( ) Close the HPI for the DSP dsk6x_hpi_read( ) Read DSP memory via the HPI dsk6x_hpi_write( ) Write to DSP memory via the HPI dsk6x_generate_int( ) Generate a DSP interrupt

22. Software (5): Project Management • Intuitive organization • Drag & drop • Fast access • Easy file manipulation • Graphically configurebuild options • Saved with each project

23. Software: Program Code Editing Features Code Composer Studio allows you to edit C and assembly source code together. The integrated editor provides support for the following activities: o Highlight of keywords, comments, and strings in color o Mark C blocks in parentheses and braces, parenthesis or brace matching o File Find and replace, and quick search o Context-sensitive help o Custom key commands

24. Software: Edit and Build with CCS

25. Software: Debugger in CCS • Debugging is optimized for DSP • C expression based conditional breakpoints • Advanced breakpoints • View source and dis-assembly simultaneously • C and Assembly debugging • Advanced Watch Window • Multi-processor debug • Global breakpoints • Synchronized control over groups

26. Software: What is DSP/BIOS? • A scalable real-time kernel for applications • Real-time scheduling and synchronization • Host-to-target communication • Real-time instrumentation • DSP/BIOS provides • Preemptive multi-threading, hardware abstraction, real-time analysis, and configuration tools • Packaged as a set of modules that can be linked into an application • Integrated with CCSTM, requires no runtime fees, and is fully supported by TI • Supports the TMS320C6000 DSP platform • DSP/BIOS Users’ Guide SPRU303B.PDF

27. Software: eXpress DSP Support Libraries • Chip Support Library (CSL) • Board Support Library (BSL) • DSK version • EVM version • DSPLIB • C62x version • C64x version • Image/Video Library (IMGLIB) • C62x version • C64x version

28. Software: Chip Support Library (CSL) • Provides a C-language interface for configuring and controlling on-chip peripherals. • It consists of discrete modules that are built and archived into a library file. • Each module relates to a single peripheral with the exception of several modules that provide general programming sup-port, such as the interrupt request (IRQ) module which contains APIs for interrupt management, and the CHIP module which allows the global setting of the chip. • SPRU401.PDF

29. Software: Chip Support Library (CSL)

30. Software: DSK Board Support Library (BSL) • BSL is a set of APIs used to configure and control all on-board devices • To make it easier for developers by eliminating much of the tedious grunt-work usually needed to get algorithms up and running in a real system

31. TMS320C6416 DSP Starter Kit (DSK) The TMS320C6416 DSP Starter Kit (DSK) developed jointly with Spectrum Digital is a low-cost development platform designed to speed the development of high performance applications based on TI´s TMS320C64x DSP generation. The kit uses USB communications for true plug-and-play functionality.   Link: Reference Manual

40. Laboratory Exercise: DSK Hardware Setup (1) Connect the following cables: • USB. • Audio cables. (2) Connect the power and observe the Power On Self-Test (POST) (Refer to Slide 15). (3) A . If using the DSK6416 Configure and test the DSK with the utilities shown below:

41. Laboratory exercise: DSK Hardware Setup Notes: • The SDRAM may take a while due to the large amount of SDRAM on the ‘C6416 DSK. • The CODEC test performs two operations: (1) a 1kHz tone output, and (2) an audio input to output loopback. You must have a speaker connected to the the output jack to hear the test. • If the confidence test fails: (1) Remove the power and parallel cable from the DSK. (2) Reset your PC. (3) Reconnect the power and the parallel cable. (4) Invoke CCS.
