hi,
You can go through the assembly code below. So that u can write in
C.
If you have any quires feal free to contact me.

.include"C:\Program Files\Atmel\AVR Tools\AvrAssembler\Appnotes\m32def.inc"

.dseg
.def temp =r16

.cseg
.org $000
rjmp bhanu

bhanu:

ldi temp,low(ramend)
out spl,temp
ldi temp,high(ramend)
out sph,temp

sbi ddrd,4
sbi portd,4

ldi temp,$0f
out pind,temp

ldi temp,$21
out tccr1a,temp
ldi temp,$05
out tccr1b,temp
clr temp
out tcnt1h,temp
out tcnt1l,temp
again:

clr temp
out ocr1bh,temp
ldi temp,$00
out ocr1bl,temp

rcall delay

sw1:
sbic pinb,1
rjmp sw1

rcall two

sw2:
sbic pinb,2
rjmp sw2
rcall three

sw3:
sbic pinb,3
rjmp sw3
rcall four

rcall delay

rjmp again

two:
ldi temp,$20
out ocr1bl,temp
clr temp
out ocr1bh,temp
ret

three:
ldi temp,$90
out ocr1bl,temp
clr temp
out ocr1bh,temp
ret

four:
ldi temp,$f0
out ocr1bl,temp
clr temp
out ocr1bh,temp
ret

delay:
ldi r26,$10
d3:ldi r27,$ff
d2:ldi r28,$ff
d1:dec r28
brne d1
dec r27
brne d2
dec r26
brne d3
ret
