INDEX variables

[J Bury <dpm-at-peopleweb.com>]

Hey there.

 I use EMC with a servo-to-go card. In the INI there is 
a section for specifying which pin certain signals get 
written to or read from. In the emc.ini snippet below there 
appear to be 3 sections ("digital in", "digital out", and 
"analog out"). What STG port do these sections map to 
(Port A, B, C, D, or none of the above)? 

Quick example: 
 *IF* "digital out" goes to Port C, and my servo-to-go 
 base address is 0x200 then:
 
 The effective address of port C becomes 0x200 + 0x404 = 0x604
 
 So SPINDLE_FOWARD_INDEX occupies bit 1 of the byte 
 at 0x604

 Which I would then read as voltage at the real world pin 13 
 of connector P1

 ..... does this sound right?


Im really having trouble relating these ambiguous "INDEX" INI 
variables to physical pins. Can anyone help?

emc.ini snippet: ----

[EMCIO]

; digital in bits

ESTOP_SENSE_INDEX         =     1
LUBE_SENSE_INDEX          =     2

; digital out bits

SPINDLE_FORWARD_INDEX     =     1
SPINDLE_REVERSE_INDEX     =     0
MIST_COOLANT_INDEX        =     6
FLOOD_COOLANT_INDEX       =     7
SPINDLE_DECREASE_INDEX    =     8
SPINDLE_INCREASE_INDEX    =     9
ESTOP_WRITE_INDEX         =     10
SPINDLE_BRAKE_INDEX       =     11

; analog out bits

SPINDLE_ON_INDEX          =     3
