Debugging Loading of the executable code. Running in real-time or step by step. Breakpoints. Profiling. Saving memory contents in a file. Waveform representation of memory contents.

To Build an Executable File

Source files (C,C++ and/or assembly) (*.c,*.asm) Text files with strict syntax checking, especially for

assembly language *.asm.

Linker command file (*.cmd)

Project file (*.pjt) : Act as a makefile for CCS. Defines all the source files and the linker command

file needed to build an executable file.

DSK5416 Audio Resources

Audio CODEC (PCM3002) : stereo codec x64 oversampling ADC-DAC converter:

– 16 bits, 48 kHz (default settings) (possible sampling frequency are 24 , 12, 8, 6 kHz).

Use McBSP 2 for data I/F to the DSP Control I/F is done through CPLD registers:

– CODEC L (IO@0002h) and CODEC H (IO@0003h) to send command word to the codec.

– CODEC CLK (IO@0007h) to set the sampling frequency.– MISC[7] and MISC[0] (IO@0006h) for status.

Analog Interface Input

Analog Interface Output DAC outputs are send to both outputs : line and Speaker

through an audio power amplifier for this one.

DSK5416 AudioTutorial Write a program that takes input samples from the ADC and writes back them

to the DAC. Create a new project, then add this configuration file audioIO.cdb (which

configures McBSP2), the function main( ) could be this one :

Further Activities

Application 1 for the TMS320C5510 DSK: The first in a series of applications to show practical

applications of Digital Signal Processing (DSP) with the TMS320C5510 DSK.

Template for an audio project. Sets up the audio codec, the 4 user switches to control the program and the 4 LEDs to act as a bargraph display. This project template can be used as the starting point for new projects.
