V1.20 Quick Start Readme

1 Device Support:

This software package supports 281x devices. This includes the following: TMS320F2812,

TMS320F2811, TMS320F2810, TMS320C2812, TMS320C2811, TMS320C2810,

TMS320R2812, and TMS320R2811.

Throughout this document, TMS320F2812, TMS320F2811, TMS320F2810, TMS320C2812,

TMS320C2811, TMS320C2810, TMS320R2812, and TMS320R2811 are abbreviated as F2812,

F2811, F2810, C2812, C2811, C2810, R2812, and R2811, respectively.

2 Introduction:

The DSP281x peripheral header files and example projects included in (SPRC097) facilitate

writing in C/C++ Code for the Texas Instruments ‘281x DSPs. The code can be used as a

learning tool or as the basis for a development platform depending on the current needs of the

user.

• Learning Tool:

This download includes several example Code Composer Studio™

†

projects for a ‘281x

development platform. One such platform is the eZdsp™

††

F2812 USB from Spectrum

Digital Inc. (www.spectrumdigital.com).

These examples demonstrate the steps required to initialize the device and utilize the on-

chip peripherals. The provided examples can be copied and modified giving the user a

platform to quickly experiment with different peripheral configurations.

These projects can also be migrated to other devices by simply changing the memory

allocation in the linker command file.

• Development Platform:

The peripheral header files can easily be incorporated into a new or existing project to

provide a platform for accessing the on-chip peripherals using C or C++ code. In addition,

the user can pick and choose functions from the provided code samples as needed and

discard the rest.

To get started this document provides the following information:

• Overview of the bit-field structure approach used in the DSP281x C/C++ peripheral header

files.

• Overview of the included peripheral example projects.

• Steps for integrating the peripheral header files into a new or existing project.

SPRC097 Version 1.20 Quick Start Readme

• Troubleshooting tips and frequently asked questions.

• Migration tips for users moving from the previous release V.58 to V1.00 and newer.

Finally, this document does not provide a tutorial on writing C code, using Code Composer

Studio, or the C28x Compiler and Assembler. It is assumed that the reader already has a 281x

hardware platform setup and connected to a host with Code Composer Studio installed. The

user should have a basic understanding of how to use Code Composer Studio to download code

through JTAG and perform basic debug operations.

2.1 Revision History

V1.20 makes some minor corrections and comment fixes to the header files and examples, and

also adds a separate example folder, DSP280x_examples_ccsv4, with examples supported by

the Eclipse-based Code Composer Studio v4. V1.11 is a minor release with only a few updates

to fix bit name typos and add clarity to examples. V1.10 is a release to fix multiple typos and

errors in V1.00 and to add new examples. A detailed revision history can be found in Section 9.

An errata listing known typos and errors not fixed in this release to prevent code incompatibility

for users between V1.00 and the newest version can be found in Section 10.

2.2 Where Files are Located (Directory Structure)

As installed, the C281x C/C++ Header Files and Peripheral

Examples (SPRC097) is partitioned into a well-defined

directory structure. By default, the source code is installed

into the c:\tidcs\c28\DSP281x\<version> directory.

Table 1 describes the contents of the main directories:

V1.20 Quick Start Readme

Table 1. DSP281x Main Directory Structure

Directory Description

<base> Base install directory. By default this is c:\tidcs\c28\DSP281x\v111. For the rest

of this document <base> will be omitted from the directory names.

<base>\doc Documentation including the revision history from the previous release.

<base>\DSP281x_headers Files required to incorporate the peripheral header files into a project .

The header files use the bit-field structure approach described in Section 3.

Integrating the header files into a new or existing project is described in Section

<base>\DSP281x_examples Example Code Composer Studio projects based on the DSP281x header files.

These example projects illustrate how to configure many of the ‘281x on-chip

peripherals. An overview of the examples is given in Section 4.

<base>\DSP281x_examples_ccsv4 Example Code Composer Studio v4 projects compiled with floating point unit

enabled. These examples are identical to those in the \DSP281x_examples

directory, but are generated for CCSv4 and cannot be run in CCSv3.x. An

overview of the examples is given in Section 4.

<base>DSP281x_common Common source files shared across a number of the DSP281x example

projects to illustrate how to perform tasks using the DSP281x header file

approach. Use of these files is optional, but may be useful in new projects. A

list of these files is in Section 7.

Under the DSP281x_headers and DSP281x_common directories the source files are further

broken down into sub-directories each indicating the type of file. Table 2 lists the sub-directories

and describes the types of files found within each:

Table 2. DSP281x Sub-Directory Structure

Sub-Directory Description

DSP281x_headers\cmd Linker command files that allocate the bit-field structures described in Section 3.

DSP281x_headers\source Source files required to incorporate the header files into a new or existing project.

DSP281x_headers\include Header files for each of the 281x on-chip peripherals.

DSP281x_common\cmd Example memory command files that allocate memory on the ‘281x devices.

DSP281x_common\include Common .h files that are used by the DSP281x peripheral examples.

DSP281x_common\source Common .c files that are used by the DSP281x peripheral examples.

3 Understanding The Peripheral Bit-Field Structure Approach

The DSP281x header files and peripheral examples use a bit-field structure approach for

mapping and accessing peripheral registers on the TI ‘281x based DSPs. For more information

on using this technique, refer to the application note Programming TMS32028xx and 28xxx

Peripherals in C/C++ (SPRAA85).

This application note explores the hardware abstraction layer implementation to make C/C++

coding easier on 28x DSPs. This method is compared to traditional #define macros and topics of

code efficiency and special case registers are also addressed.

4 Peripheral Example Projects

In the DSP281x_examples\ directory of C281x C/C++ Header Files and Peripheral Examples

(SPRC097) there are several example projects that use the DSP281x header files to configure

the on-chip peripherals.

4.1 Getting Started

4.1.1 Getting Started in Code Composer Studio v3.x

To get started, follow these steps to load the DSP281x CPU-Timer example. Other examples

are set-up in a similar manner.

1. Have an F2812 eZdsp or other hardware platform connected to a host with Code

Composer Studio installed.

2. Load the example’s GEL file (.gel) or Project file (.pjt).

Each example includes a Code Composer Studio GEL file to automate loading of the

project, compiling of the code and populating of the watch window. Alternatively, the project

itself can be loaded instead of using the included GEL file.

To load the CPU-Timer example’s GEL file follow these steps:

a. In Code Composer Studio: File->Load GEL

b. Browse to the CPU Timer example directory: DSP281x_examples\cpu_timer

c. Select Example_281xCpuTimer.gel and click on open.

d. From the Code Composer GEL pull-down menu select

DSP281x CpuTimerExample-> Load_and_Build_Project

This will load the project and build compile the project.

3. Edit DSP28_Device.h

Edit the DSP281x_Device.h file in the DSP281x_headers\include directory and make sure

the appropriate device is selected. By default the 2812 is selected.
