connecting ADSP-21992 EZ-KIT LITE to RS232

Started by Hany Ferdinando March 20, 2003
Hi all,

I am using ADSP-21992 EZ-KIT LITE. There is DB9 for RS232 serial port on this
board. I would like to connect this board to PC via RS232 to do some data
aquisition. I will use VisualDSP++ 3.0 to write the code.

Has anyone on this mailing list ever done such as this? Would you guide me to
do that? I found no information on its manual. regards,

Not on that board, but I have on the 21061 EZKIT. Is there a UART
you have access to, either built into the chip or external (on the
21061 it's external). Find the specs on that UART, and program it to
send and receive data. Try to find the fastest rate the PC will
support. I'm assuming you have an alternate way of loading code
into the EZ-KIT - like JTAG or USB. If not, life becoms a touch more
difficult - you have to load your code, then use the same i/o lines
to send your data. On the 21061 you could do that with calls to built
in commands.

It's doable for sure. But you'll need to figure out how to attack the
problem based on how the board talks to the VDSP loader.
