Alright guys I need your help on this program. I am trying to print out 3-digit hex numbers increasing by 345 each time. I understand in assembly I am supposed to print each part of the hex number individually. I would do this by doing shifts "lsr", yet I am getting a wrong number for the first part of the number. The first number after 0 should be 149 (345 in decimal) but I am getting A59 (2649 in decimal).
heres the my code
.globl _start
_start:
ldr r4,=0x101f1000
mov r0, #0x00
lsl r0, #4
add r0, #0
mov r5, #0xBB
lsl r5, #4
add r5, r5, #8
my_loop:
cmp r0, r5
bgt my_exit
lsr r1, r0, #6
and r1, r1, #0x0000000f
cmp r1, #10
addlt r1, r1, #48
addge r1, r1, #55
str r1, [r4]
lsr r1, r0, #4
and r1, r1, #0x0000000f
cmp r1, #10
addlt r1, r1, #48
addge r1, r1, #55
str r1, [r4]
lsr r1, r0, #0
and r1, r1, #0x0000000f
cmp r1, #10
addlt r1, r1, #48
addge r1, r1, #55
str r1, [r4]
mov r1, #13
str r1, [r4]
mov r1, #10
str r1, [r4]
add r0, r0, #99
add r0, r0, #99
add r0, r0, #99
add r0, r0, #48
b my_loop
my_exit:
我只是发现我的移位不正确,应该是8位而不是6位。还要感谢@Michael给出了相同的答案。
