'C6711DSK RTDX

Started by Guilherme Piazaentini Colnago February 14, 2005


Hi folks,

I'm working with the 'C6711DSK board and I need read a PC file. I'm
reading a file with fread(), but it's very slow.
A frined talks about the RTDX. How can I use this method? Anyone has
a example?

Regards,
Guilherme.


Hi Guilherme,
 
I assume that you are using the parallel port to communicate with your DSK.  If this is true, the fastest way that I have found to transfer data from the PC to the DSK is via HPI.  This requires a simple program on the PC.
 
Refer to
\examples\dsk6711\board_util\conftest\Host\
\examples\dsk6711\board_util\conftest\Dsp\
6711DSK Help->confidence test
 
This will explain one way to communicate and transfer data between a PC and 6711 DSK.  The HPI transfers will be faster than program loads or RTDX when using the parallel port.

Guilherme,
 
It is very easy.  Check example files [and help files] for the use of functions that begin with 'dsk6x_hpi_'.

Thank you Mike,
 
I'm reading the example. In fact, I'm changing the host C code.
 
One more question. After I've read the file (host), how can I put it on SDRAM (I don't know)?. Could you suggest anything?
 
Regards,
Guilherme
