Control of a TI C6xxx DSK

Started by Hans Fugal April 27, 2006
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. Cheers, Howard

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:
