Streams with the ADSP-218x Debugger

Started by robmcevoy December 19, 2003
Hi,

I'm trying to write a program for my ADSP 2189M Ez-Kit Lite board,
which takes in data samples from a Codec on SPORT0 and transmits the
results over SPORT1 to a binary file.

Is this possible? In the ADSP 218x examples that were given with the
Visual DSP++ software, there is an example (Example 2) for the 2181
that takes data from an input file and transmits the same data to an
output file. However, when I try to set up the Settings for the
streams in the Visual DSP++ debugger, the 'Streams' option is grayed
out!

Does it annoy anyone else that nearly all the examples given with
the Ez-Kit board pertain to the 2181, and don't work on the 2189?

Thanks in advance,

Rob




Hello,

I think the "streams" feature of VDSP++ works only
for a simulation session, not for emulation or EzKit
session (which is really a pitty).

However, one workaround that comes to my mind is:

Capture data from CODEC, process it and store
processed data into memory (the '89 has rather big
memory on chip). Then perform a Memory->Dump
operation, to get the processed data into a data file.

Regards,
