connecting a t6963 display to the parallel port:

intro

serdisplib supports two pre-defined wirings, user specific wiring is also possible through customisable wiring

pre-defined wirings

  • valid for all pre-defined wirings: D0 to D7 are wired to pin 2 to 9
  • "WIRING=Standard"
           CE .. pin 14 (nAUTO)
           CD .. pin 16 (INIT)
           WR .. pin  1 (nSTRB)
           RD .. pin 17 (nSELIN)
          
  • "WIRING=Windows"
           CE .. pin  1 (nSTRB)
           CD .. pin 17 (nSELIN)
           WR .. pin 16 (INIT)
           RD .. pin 14 (nAUTO)

passing options through serdisp_init():

intro

using the third parameter of serdisp_init(), driver specific options and custom wiring can be set.
common information about passing options and customisable wiring can be found in a separate document.
    examples:
    
      serdisp_init(sdcd, "T6963", "WIDTH=128;HEIGHT=64;WIRING=Windows");
      serdisp_init(sdcd, "TLX1391", "INV=YES");
