FPGA Central

I'm new to the TI boards, and would like to control parameters of a DSP
project external to the board. Over Serial, USB, whatever. In the
software world I would use MIDI, but I see no MIDI libs for the TI
boards. I see documentation on the hardware of McBSP and so on, but if
I'm to do this it's going to have to be at the C level; I don't have
time to write a serial driver from scratch.

I seem to be spinning my wheels, so I wonder if somebody could point me
in the right direction for simple external control of parameters. Thanks

You don't say which DSK it is. If it is the '6713, there is an I2C port
available that is presented on the HPI header.

The board is '6416. I was able to borrow a book [1] that has cleared it
up nicely. The magic words are RTDX and OLE. I should probably be able
to code up a simple GUI using Ruby (with FXRuby or Tk, using the
win32ole library) to control the parameters.

Sigh. Forgot the book info:
