;***** PROGRAM CONSTANTS
; Timer0 Prescaler 1:8
Ctimer0 equ .8 ; timer0 reload value 2mS (refresh 100Hz)
;Ctimer0 equ .132 ; timer0 reload value 1mS (refresh 200Hz)
; 5 layers x 2mS = 10mS -> 100Hz refresh
; Changing the refresh will affect the hold and second timers in the lc5x5_inth.inc code
;***** VARIABLE DEFINITIONS
cblock 0x20

vox.x ; X axis voxel pointer register (GPReg 5)
vox.y ; Y axis voxel pointer register (GPReg 6)
vox.z ; Z axis voxel pointer register (GPReg 7)
voxel.count ; Used by SET/CLR/INV ALL drawing functions
rotate ; temp variable used to rotate cube in the x-axis
addr.stack.pointer ; instruction pointer stack -35
user.stack.pointer ; current stack pointer address
stack.data.temp ; temp variable holding value to put on stack

randomL ; Random number lo byte
mult.mult2 ; Multiplier to scale random number for use
mult.resHi ; Multiplier to scale random number for use
mult.resLo ; Multiplier to scale random number for use
math.op1 ; math operation variable
savex ; Temp save of X,Y,Z registers when draw functions
savey ; use them but they need to be left unchanged on
savez ; function exit
lastone
endc
cblock 0xA0
buffer.disp:.25 ; must be offset from buffer.draw by 128 bytes
addr.stack:.16 ; instruction pointer return address stack
user.stack:.33 ; user software stack
; user stack is 30 levels deep but the Drawing Processor also
; makes use of this stack for temporary storage during
endc ; instruction exectuion so 3 extra bytes are reserved
cblock 0x70
w_temp ; variable used for interrupt context saving (also used in startup code)
status_temp ; variable used for interrupt context saving (also used in startup code)
pclath_temp ; variable used for interrupt context saving

flag.bit ; Variable used to hold flag bits
voxel.func ; Variable used to hold voxel mode operations
shift.register ; Temp variable used to shift drawing buffer data to hardware shift registers
layer.select ; Variable holds current layer output drive
shift.count ; Bits shifted counter
hold.timer ; display update hold timer in 10mS intervals
tick ; Count of 10mS periods in 1S
seconds ; Seconds countdown timer
inst.ptr.Lo ; drawing processor instruction pointer Lo byte
inst.ptr.Hi ; drawing processor instruction pointer Hi byte
char.ptr.Lo ; character data address pointer Lo byte
char.ptr.Hi ; character data address pointer Hi byte
endc
; Flag bits
Fcopy.buffer equ 0 ; Set when draw.buffer ready to be transfered to disp.buffer
Fhold.tout equ 1 ; Set when hold delay has completed
Fzero equ 3 ; Flag is set to indicate a value is 0 (zero)

arkadaşlar burada 5x5x5 led küp devresi için yazılmış asm kodu var kodun orjinalinde küp animasyona başlarken site isminin harflerini tektek yazdıktan sonra animasyona geçiyor.Bu kod içerisinde harflerin oluşturulduğu komut satırının hangisi olduğunu bilmiyorum daha doğrusu asm bilmiyorum bu kodu C dilinde yazabilecek arkadaşların yardımına ihtiyacım var.Yardımcı olursanız sevinirim.
