Hi ranjan, I would like to have a look at your source code and try to figure out what needs to be done to Increase the performance. Can you tell me where can I look for the code, or can you mail me the code. What software have you used on the PC to make a graph?? On Thu, Oct 1, 2009 at 7:04 PM,

What are the accelerometers used in the FR (company and model number)?I think it might be Freescale's MMA7260.If it is it has selectable sensitivities in the range of +/- 1.5 g to 6 g what has been selected in the free runner.What I observed is that the Free runner is able to detect shocks as

Freerunner uses the LIS302DL accelerometers from ST [1]. They can be switched between +-2g and +-8g range and have a resolution of 8 bit per axis. The sample rate can be selected between 100Hz and 400Hz. And they inherit some nice functions like double click detection and zero-g filtering.

I have been testing the accelerometers on the free runner via bluetooth at 38400 bps.Here is my test video: http://www.youtube.com/watch?v=Bdads8XAYcEhttp://www.youtube.com/watch?v=Bdads8XAYcE I think at 38400 it is not pretty real time.What could be the maximum refresh rate of the
