Hi everybody,
I'm new in this group and I have no experience in programming dsp.
I have a TMS320C6713 DSK board from Spectrum Digital that can be
connected to the pc using USB port and a daughterboard AED-103 from
Signalware with 16 ADC and 2 DAC.
I have 2 questions:
- the DSK must be supplied with +/-12V through the ausiliary power
connector J6 (also +5V) and I thought to use a standard PC's ATX power
supply that gives me +/-12V , +/-5V and +3.3V. The problem is that I
don't know how much current the DSK and the daughterboard need. A
normal PC's ATX 400W power supply gives:
5V 35A
12V 16A
-12V 0.8A
I think it's sufficient for the 5V and 12V lines but I'm not sure
it'll be sufficient for the -12V line. Does anyone have an idea how
much current the -12V line needs? Is it a good idea to use a PC's ATX
power supply?
- The first work I have to do for my thesis is to import the data of
16 microphones that will be sampled by the 16 ADC of the
daughterboard. I thought that I could transfer this data to the PC
through the USB port of the DSK (connected to the PC) to analyze them
using matlab. Is it possible? Do you have any suggestion?
Thank you for your help

The only user [if any] of -12v would be the
daughtercard. It should have a specification for the
-12v, although I am confident that it doesn't exceed
800ma.

It is economical, widely available, and proven.

Not really. The USB on the 6713 appears to be
dedicated to the debug JTAG port - you cannot use it
as a general purpose USB port.

TI's web site shows a third party [educational DSP]
that has an economical HPI card. [I keep telling
myself that I am going to evaluate it someday...]
