Yep, others have reported having these problems. Here's a fix I came up
with, but has also only been tested on my system. There have been
reports that the existing code works for some, and not for others, so
you may need to customize this.
just replace the existing definitions in direct-sensor.c
hope this helps
mark
! A/D values for the rotation sensor states
//
#define STATE_0_VALUE (0x0f000)
#define STATE_1_VALUE (0x0d000)
#define STATE_2_VALUE (0x07000)
#define STATE_3_VALUE (0x0a000)
//! rotation sensor range matching function
//
#define IN_RANGE( val ) ((raw & 0x0f000) == val)
void ds_rotation_set(unsigned* const sensor,int pos) {
unsigned channel=(unsigned) (sensor-&AD_A);
unsigned raw = (*sensor);
RotationState state;
if(sensor>=&AD_A && sensor<=&AD_C) { // catch range violations
//determine initial position
if(IN_RANGE(STATE_0_VALUE))
state=STATE_0;
if(IN_RANGE(STATE_1_VALUE))
state=STATE_1;
if(IN_RANGE(STATE_2_VALUE))
state=STATE_2;
if(IN_RANGE(STATE_3_VALUE))
state=STATE_3;
rotation_state[channel]=state;
ds_rotations[channel]=pos; // reset counter
}
}
