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, Hany Ferdinando MSc Student on Embedded Control System University of Twente The Netherlands |

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. Patience, persistence, truth, Dr. mike |
