MMA7455 acceleration values unstable
I´m having a problem with acceleration values with MMA7455. The values changes too much even when the device is not moving.
I tried to adjust ofsets
Offset values FOR each axis:
'Offset values FOR each axis:
XCal CON 25 'VAR Word
YCal CON 80 'VAR word
ZCal CON 0 'VAR Word
but even so the values for XAccel changes like these ones captured from my accelerometer (see atached figure):
I´m using MMA7455 with a BS2p and with the software MMA7455L 3-Axis Accelerometer Demo (PBasic) v1.0 DEMO#1.bs2
All the axis have unstable values.
However the values seem to be coherent when you move the device. For instance, Z value is 63-69 (1 g) When you move the device you can see the values going from -63 to -69 (-1g).
