Hello

I am working with a RB-110 with an Ubuntu running as O.S. I have a developed a program to control a quadrotor that is composed of several threads(one for sensoring and actuation, one for communication, one for control and so on). I have realized that my top speed of the threads is 250 Hz i can not go any faster, is this normal? That is the top frequency of the computer, i will like to get to 1MHz.


Thank you very much.

Andreu

Hi,

you may employ a real-time kernel for higher context-switching rate. But in general, for both WinXP & Linux, it is difficult to get 1MHz context switching.

I am sorry i dont want 1MHz with 1 Khz i will be happy enough, i think the real time idea could be good, thought.
