You have to implement the Goertzel Algorithm for DTMF decoding. Here is a microcontroller based project with schematic and full source code: **broken link removed**
winrar crc error
Try to repair them with WinRAR (from the Tools menu choose Repair archive). If it doesn't work, download some of the software available on the internet (search for "winrar repair" in Google)
Here you can find some introductory tutorials about character recognition:

Hi
I'm looking for the paper "Map image segmentation based on thresholding and fuzzy rules". It can be downloaded from **broken link removed**
If someone has account for IEEE digital library site, please download it and attach it.
Thanks in advance!
tms320c6713 example
Hi Ahmed,
Thank you for the link, the project is very useful.
My DSP Kit came with 2 CD's, one with C6713 DSK Code Composer Studio and the other with 30 day evaluation version of Matlab. The installation of the CCS IDE is easy, and there are some examples in C, which can be...
project on audio coding using tms320c6713
Hi ahmedseu
I bought the TMS320C6713 DSP Starter Kit (DSK) from the local distributor of Texas Instruments for $395.
You can order it online through TI web site:

It would be cheaper to use microcontroller with all the peripheral controllers integrated in it instead of connecting external ethernet or USB controller chips.
LPC2368 is a good choice, it has Ethernet 10/100 MAC with DMA, USB 2.0 Full Speed Device Controller and SD/MMC memory-card interface.

As metal said, there is USB protocol implementation in firmware for small microcontrollers without USB controller. Of course it is USB 1.1 and is much slower than USB 2.0
The most famous project is from Igor Cesko for AVR's.
See the attached file or download it from his site...
The most suitable compression algorithm for you is IMA-ADPCM. It can be easily implemented in a small microcontroller. The IMA-ADPCM algorithm takes 16-bit samples and compress them down to four bits each, that is 4:1 compression ratio.
The compression is lossy and the reconstructed sound is not...
Give more details about your project
What kind of data do you want to compress (text, sound, images)? And do you want to be able to compress & decompress the data in the microcontroller or only to decompress it (the compression to be done in a PC)?
The choice of the optimal algorithm depends on...
