Re: [Paparazzi-devel] update rate for IR sensor

[C.KUO]

Hi Arun

  We are at moment building from scratch, but use the reference from  
IMU from sparkfun (Razzor 9DOF IMU). and we use the monitor software  
from it as well, it go though UART.

  The system react ok from the itself when we monitor on the display,  
but we do trying now wire it though Tiny2.1, but we don't know if the  
update rate is enough (in theory, the update rate of the sensor itself  
should be at 50Hz, but after going though spi, is it still 50Hz or  
less?)


  I was wondering what is your approach? same idea? or you want to do  
all the computation on LPC2148?

  Anyway, it is nice to know people are having the same goal :D


Regards

                                                                    Chen
