Sharc data rate

Started by Rakesh GnanaDavid July 11, 2004

Hi
 
I'm using the ADSP 21160 EZKIT LITE for a project. In it I want  to use the sport0 for getting a 50 bps data. While setting the RDIV0 for sport0 the maximum divisor that can be used is FFFF( only 16 bits). This gives the minimum data rate to be roughly 600 Hz. ( taking into account the max clock rate 80MHz).  How could I solve my problem. ( I don't want to oversample my data).

The serial port can only go so slow. So you will either need to
use some external hardware, or emulate a serial port yourself
using GPIO pins. At 50 bps, there would be very little processing
required to implement a serial port.

Just curious, why so slow?
