Assembler code

caskaz

Hi Guys.

I start to study assembler, and soon I 'm confused.
I use Demo-board.

sample code below:

VAR
  long d
OBJ
  debug : "FullDuplexSerialPlus"
PUB main
  debug.start(31,30,0,57600)
  debug.tx(Debug#CLS)
  dira[noparse][[/noparse]16]~~
  cognew(@entry, @d)

  repeat
    !outa[noparse][[/noparse]16]
    debug.hex(d, 8)
    debug.str(String(" "))
    waitcnt(clkfreq/5 + cnt)

DAT
          org
entry  mov t1, ina
         and t1, mask
         wrlong t1, par
         jmp #entry

t1      res 1
mask  long $00010000

It display "28000000" on PST. Still same, no change.

I commented "and t1, mask".
It display to repeat "FE00007C" and "FE01007C". P16'state is read.

"mask long $00010000" is mistake?
What is correct expression?

Is there good text for assembler?

Any res has to be after any code and/or data in your program. In your case swap the last two lines:

mask    long    $00010000
t1      res     1

Thans!.

Have a look at Propeller: Getting Started and Key Thread Index. It's not all about assembler but you can obviously skip the stuff you don't need.
