Help modifying an object.

Dgswaner

I'm trying to get the PropDOS object to work, but to do so I need to change the pin assignments. it's written in assembly so I can't tell were and what to change. I would really appreciate some help.

the defaults are:

p0--DO
p1--CLK
p2--DI
p3--CS

I need:

p16--DO
P17--CLK
p18--DI
p19--CS

There aren't any constants that I can change and I already had my 0-3 pins soldiered as well as 16-19. It's actually the SDSPIASM.SPIN that I need changed.

Thanks I really appreciate it.

Why not change the pin assignments in the CON section of PropDOS itself?

Personally, I'm a fan of using 16..19 for SD because it opens 0..7 for things
like game controllers, and it most compatible with Hydra stuff (games)

OBC

CON
  '' I/O SETTINGS

   _clkmode  = xtal1 + pll16x
   _xinfreq  = 5_000_000
  
  '' Adjust for typical location of the keyboard. Usually 26 on the demoboard
  
   keyboard  = 26
   video     = 12
   
  '' Typical Demoboard/Protoboard Configuration
  
   spiDO     = 16
   spiClk    = 17
   spiDI     = 18
   spiCS     = 19

wow oddbit I think I owe you dinner or something, for wasting so much of your time tonight. and I think I need to go to bed, I'm making too many dumb mistakes. Sorry it's not PropDos but "FAT16 routines with secure digital card layer" Object http://obex.parallax.com/objects/92/ I was going to use PropDos but it requires a keyboad, which I can't easily connect because of connections I have added. This object doesn't have constants for the pin settings. I think I'll Just rewire my board tomorrow, that way I won't be limited on other objects too.
