diegogubellini Member Licensed User Longtime User Jul 15, 2014 #1 Hello all I used the code showed in this tutorial to get the signal of two accelerometers: http://www.b4x.com/android/forum/threads/orientation-and-accelerometer.6647/ I need a quite high sampling rate in the accelerometers and after apply a IIR filter. The updating of value of accelerometers is made by the sub _onchanged. The problem I have is the frequency of the app update the value of each sensors. Moving the phone the value changes (more less) 3-4 times per second. I would like to obtain a frequency of (at least) 20-30 Hz. There is some parameters that I can change to have more. I tested the app in two differents phone: huawei ascend y300 and samsung galaxy S4 and the result is the same... Let say it does not matter of the power of phone. Thanks for help
