Hi! This is my first post here.
I am working on a project which involves working on ADXL345 and Arduino UNO. ADXL345 is supposed to detect impacts in all directions.
I am using ADXL345 in 10-bit resolution with +/-16g range.
I have been facing a number of problems here :
1. Despite putting ADXL345 on a flat surface there is an offset in Axis - Z values.
2. MAJOR PROBLEM!!! : While I was doing some controlled testing to set a threshold, I put the value of TapThreshold as 170 (~5g). I tried to hit it softly and observed that it is detecting a tap. The value of force was nowhere close to the threshold.
I re-checked all the connections but this thing is getting out of control now.
You can get the library files here : http://bildr.org/?s=accelerometer (Tap! Tap!....)
Any help would be appreciated.
Thanks!
