I want to use Visual DSP++ 3.5 to talk to an old 21061 EZ-Kit lite (and eventually a 21065L EZ-Kit) via RS-232. However, I can't seem to set-up an appropriate session in Visual DSP++ 3.5.

I choose that, but now my only choices for processor a...

Hey, I'm implementing a flanger effect as part of a guitar effects processor on an ADSP-21364 development board. A Flanger effect is produced by adding a single delay to the current input sample. The duration of this delay is determined by the magnitude of a low frequency sin wave. The values I am using are: 1Hz sin wave, values in a lookup table max 3ms delay => 144 samples in de

Hi, I was looking to develop a code strip the header details in the .wav file & convert it into a .dat file. I have the C code which does this in VC++, which runs well. But since the data types in VDSP++ are all 4 bytes, I cannot read the data in a .wav file byte by byte. Do you have a code which works in VDSP++ (converting .wav to .dat)? Can u suggest something?
