Hi All Friends!

I think convert Standart Morse Code to Hex. Morse Code items like binary numbers.

I accepted short item (.) = binary 0 and long item (-) = binary 1. For example, national standart
help code is s.o.s and morse code is : ...---... if us want convert this code : 000111000 ok.

Result is like this:



win32asm = .--..-....--..---.-...-- (18) 6433A30000 = 011001000011001110100011


First number is always total bit lenght. I used bit length because last byte not complete mostly.

Sincerely, have nice days!

Error here:


mov ecx,8 ; 8 per bit
div ecx
must be


mov ecx,8 ; 8 per bit
xor edx,edx
div ecx
or better


mov edx,eax
and edx,7
shr eax,3

There was a Hugi size-coding-compo on doing a morse-converter. The entries (16bit) are still available at:

CYDONIA maybe you can update the exe too ;)
nice work btw ...

Hi Cydonia

This app crashes on Windows2000

Hi All,

:stupid: Thanks TBD I update exe file and upload again. :alright:


Thanks Beyond2000!, I try just only W9X. May be problem is lstrcat or lstrlen API's. i don't understand how to not work. I research again.

I think next version added long and short sound. Like real morse generator. But i don't know standart morse code sound frequency (if present) and between two sound timer.

Again thanks all,


have nice days!

Hi Cydonia

still not working on W2K

The error seems to be around here:


mc_retry:
lea ebx, buf2
lea edi, morsecode

lodsb --------------------------> This is weher it crashes
or al,al
jz end_cnv ; end ?
cmp al,' ' ; space ?


Regards
Beyond2000!

Remember to preserve volative registers (ebx esi edi ebp esp). Windows NT/2000/XP are especially strick about that.

CYDONIA: it still crashes on NT in USER32
i am too lazy to convert it to MASM to track the bug :)
Posted on 2002-07-24 07:17:32 by TBD
here is the converted morse2hex to MASM with these differences:
+ automatic translation - GO button obsolete
+ ESC closes the dialog
- no more hex conversion (it hangs on NT ... maybe someone
will implement a good one :grin: )

also it needs some optimizations here and there :)

Hi All!

WAW! This very cool!, thanks!
:alright:

Beyond2000! and Comrade thanks for reply, i research again and i optimize some opcodes and functions. I removed lstrcat and lstrlen APIs. I change all lodsb opcodes to mov al,, inc esi opcodes. Program work under w9x. But don't sure NT and w2k.



btw: Plus i added binary section.

Thanks all,

have nice days!

Hi All Friends,

I added two 5khz long and short sound file for sound simulation. Current version simulating like real morse code generator. I added UpDownControl for playing speed. I finished this project :) But i guess all versions not compatible NT and W2K. Now i research stacks faults and bugs :) for work NT and W2K OS's

Thanks all Friends! :alright: Shared is knowledge!

have nice days

Following attach with conversion routines may be will interesting for you.

This is probably the thread with the most attachments on this message board.

May be error here? :)


jnz setbit1
mov ecx,dword ptr [bitlow]
or ecx,ecx
jz end_cnv2
mov bl,1
jmp short [B]setbit1[/B]
end_cnv2:
lea edi,hexbuf
mov eax,dword ptr [bithigh]
mov ecx,eax

works under windows xp.

Hi All,

Thanks NeXo for nice example. Thanks Qages for XP test. And Thanks all Friends!

...


jnz setbit1
mov ecx,dword ptr
or ecx,ecx
jz end_cnv2
mov bl,1
jmp short setbit1
end_cnv2:
lea edi,hexbuf
mov eax,dword ptr
mov ecx,eax
add ecx,ecx




This section for remaining bits. If last byte not 8 bit jump again bit conversion. bl register here a key for break in loop. I removed this section and upload again. If error is here, i make with other way binary conversion.

thanks all, have nice days!

btw:Sorry my bad English...
