>From my experience with the DSK 5416, its a 16-bit
device, supporting a 16-bit data bus. So to send 8-bits all you need to do is
connect the first 8-lines of the data bus to your device. To code all u need to
do is use the port command to write to a specific address ur device is connected
ex: port8000, can read or write ta device connected to the address 8000h.

I have an dsk5416 and I want to send 8bit data to an dds(ad9850).with parallel
port. I want to use GPIO does dsk5416 support 8 bits or not? is there any code
in c for doing it? i want to use c code. would you please to help me?

DSK 5416 should support 8-bit GPIO over the daughtercard connector P3. You have
to
make sure the 5416 boots in GPIO mode and not HPI mode (look in the DSK
schematic for
HPIEN pin and what jumper or pull up/down R options are available).
For C code examples for C54x GPIO, check recent threads on this group. This has
been
discussed and C code examples were presented. It seems like there's a
bunch of
students who recently got assigned the same project :-)
