You will find hereafter some code I wrote and some infos for the DSP I use
Please note that I give this code 'as is' and I don't give any support for it
As I have time, I will put on this page some code for the following chips :

ADSP2192-12

* AC'97 interrupt support example for ADSP2192-12
The talkthru project delivered with the ADSP2192-12 EZKit-Lite is not really interesting, because there is no interrupt support.
This example shows how to handle AC'97 codec interrupts, to permit real-time audio processing

* AC97 registers definition file
An header file with AC'97 registers definition for the ADSP2192-12

* GPIO interrupt support example for ADSP2192-12
ADSP2192-12 supports GPIO interrupts, but the Hardware Reference Guide gives only a few informations about it. On this page, you will find all informations and example that show how to handle GPIO interrupts.
A specific chapter is dedicated to the problem of edge detection.

* Expanding I/O capabilities of ADSP2192-12 (In preparation)
ADSP2192-12 supports only 8 General Purpose I/O. This page explains how to expand the number of GPIO using only a few external components.

* ADSP2192-12 memory debugger (In preparation)
With Analog's Loader Utility, it's possible to transform a .DXE file into a Windows executable file which loads the program into the ADSP2192 memory, without using VisualDSP++.
This free utility allows you to access DM, PM and IO segments of a DSP running a standalone program, without needing VisualDSP++.

ADSP-21065L

* ADSP-21065L EZKit Lite audio effects demo programs
Analog Devices offers a complete collection of demo programs, showing various audio effects (chorus, reverb, etc...)
Just click on the link to go to Analog's website and find these demos
NOTE THAT THESE PROJECTS ARE NOT DIRECTLY COMPATIBLE WITH THE VISUAL DSP++ VERSION DELIVERED WITH THE EZKit !!! (see below)
* Corrected LDF files for EZKit-Lite audio processing demos (In preparation)
Analog Devices offers on its website a complete collection of demo programs, showing a lot of audio effects. These programs have been written normally for the ADSP-21065 EZKit Lite, but it seems that the author of these programs used a FULL version of Visual DSP++. Linker Definition Files have been written without taking into consideration the limitations of the DEMO version of Visual DSP++ delivered with the kit, leading to a linker error if you try to compile the audio effects projects.
I've corrected the LDF files to make them compliant with the restrictions of the demo version of Visual DSP++. Have fun with these effects !
