Setting MMA7660 for meassuring Acceleration

[sidel]

Hello,

I am using the MMA7660 Accelerometer.

I have tried the following register initialization for "NO interupts, active mode, 8 samples per second"

INTSU =  0x00;  // Interrupt Setup Register

MODE =  0x01;  // MODE" Register

SR       =  0x94;  //Sample Rate Register

PDET  =  0x00;  //Tap/Pulse Detection Register

PD       =  0x00;  // "PD"  Tap/Pulse Debounce Count Register

I am reading out the orientation angles from the chip,

Can someone plz tell what should I change in order to read acceleration measurments instead of orientation?

I have red the datasheet thoroughly but I cannot find anything about switching between orientation and acceleration readout modes.

Kind Regards,

George

The acceleration is read in the X,Y,and Z registers (registers 0,1,and 2). Gravity is of course 1G.

Thanks for your Reply Jake,

From what I have understood, the chip outputs either orientation angles or acceleration values. Both measurements are updated on X,Y,Z registers (see page 28) but somehow the mode is selected .

Untill now I can get only orientation angles on X,Y,Z registers can anyone advise how can I switch to acceleration readout?
