Interrupt I/O on TMS320C6711 DSK

Started by Benjamin M. Stocks May 6, 2004
Hi All,
I know this isn't a DSP question per say, but has anyone implemented
C-style (fscanf, fgetc, etc...) interrupt driven I/O on the
TMS320C6711 DSK using a UART with DSP BIOS? I know I can use C-style
I/O functions with a UART by using the add_device function in the
runtime library but that doesn't do interrupt driven I/O does it?
Those are more polled functions aren't they?

Thanks in advance for any help,

Ben

I'm not familiar with that particular library, but such things often use interrupt driven I/O at the actual driver, but the function itself will pend on the I/O buffer (using the OS pend, which I believe is part of TI's "BIOS"). -- Tim Wescott Wescott Design Services http://www.wescottdesign.com
