qei index pulse could not reset
PostPosted: Wed Aug 03, 2011 1:36 am     Reply with quote
Hi All,
I'm trying to use dsPic33fj32mc204 and quadrature encoder.

in main() function:
Code:

setup_qei(QEI_MODE_X4|QEI_RESET_WHEN_IDX_PULSE,QEI_FILTER_DIV_1|QEI_IDX_WHEN_A0_B0);

in timer2 interrupt:
Code:

  count=qei_get_count();


here is phsical index pulse but i could not receive it. Counter only counts upward or downward.

Does anyone have an advice?

I've tried this too;

in header file:
Code:

#define RPINR14   0x069C         //QEI remap reg
#define QEI1CON   0x01E0         //qei control register
#define DFLT1CON   0x01E2         //qei dflt control register

in main() function:
Code:

*(RPINR14)=21;     //qeb remap (my qeb pin)
*(RPINR14+1)=20;     //qea remap (my qea pin)
*(RPINR14+3)=19;     //ind remap (my index pin)

*(QEI1CON)=((*(QEI1CON)&0xFB)|0x04);      // index pulse reset enable
 *(QEI1CON+1)=((*(QEI1CON+1)&0xF8)|0x06);      //qei 4x mode, index pulse reset
 *(DFLT1CON+1)=((*(DFLT1CON+1)&0xFE)|0x01);      // count error detect disabled


Thanks in advance

*(RPINR14+2)=19; //ind remap (my index pin) //index pini rp19

I'm sorry for my broken English.
