Code: Select all
ld hl, (dcs_ptr) ; 16
ld a, (hl) ; 7
out (DCSPIN), a ; 11 lsbit is dcs bit
ld (dcs_ptr), a ; 13 and it also points to the next
struggling with it now

[quote="sigma"]If you want a 16-bit loop counter, never, ever do this:
That would be useful, if each run of the loop must be in constant time.
Just nitpicking about the "never, ever"

cyclic rotate of 23 bits
Hello, Can anyone suggest a better way ? ld hl, # dcs_bits+2 ; 8 msbits here ld a, (dcs_bits) ; 7 lsbits, leftjust rra out (DCSPIN), a ; emit old lsbit, now in A.0 rra rr (hl) ; rotate the stored bits dec l ; within a page rr (hl) dec l rr (hl) .... dcs_bits: .ds 3 ; 23 msbits rotate, lsbit is junk ...
