Description:

This project is a small example to show how to detect shocks with a MEMS. The handler detects the variations of the MEMS data (the sum of squares of the variations of x/y/z), and increment a step for each double variation.

The level is tunable (UP/DOWN with the joystick), and an hysteresis as well (LEFT/DOWN).

The number of steps, the level and the hysteresis are displayed on the LCD monitor.

The default values seem to work not too bad for a "normal" walker (I assume I am "normal").

yrt Administrator Offline	Hi, I'm not sure to understand what you are testing ? What is your Ride version ? The project is a CircleOS application, so it does not contain main function, because it is called by the OS. If you try to build this project, as it, with a recent Ride7 version (this available on this site or on Raisonance site), you wil not get any problem. Yves

Available in Primer1？ Please, log you to post a reply.

yrt Administrator Offline	Hi, Normally, this application should run on Primer1 also. The only problem could be the threshold tuning, that is done with the joystick ! Yves
