Hex Break

Post by InTheStillOfTheNight »

Program mikrokontolera se svodi samo na hex file. Što se zapravo nalazi u tim brojevima ničega? Kako iz hex-a izvući programerski source? teška pitanja i teški odgovori. U ovom topicu cu pokušati razbiti nečiji hex code i izvući izvorni source code c-a. Nadam se da me trax neće izbaciti sa lisle poželjnih jer ću izabrati neki njegov source za proučavanje... Sorry trax nema ljutnje, tu smo da nešto naučimo :) Molim nemojte komentirati ako stvarno nemate što pametno napisati... Hvala

Kad odaberem hex file pisati cu o nacinu kako to razumijeti, i kako doći do izvornog koda, a do tada:
Budite mi Zdravi, Lijepi i Pametni... Cujemo se uskoro...

Izabrao ja.. Smrdi mi nekako da je ovo Trax programirao, pa cu zato sa ove stranice:
http://www.ivica-novakovic.from.hr/IrOn ... m#IrOnOff2" onclick="window.open(this.href);return false; pokušati izući source code...

1. Osnovno.... Hex file je assembler, a svaka firma i svaki procesor ima različite kodove assemblerskih naredbi... Sreća pa na ovoj stranici znamo da se radi o Hex file-u PIC12F629.

Što znamo?
Hex je za procesor PIC12F629!!!

Što dalje?
http://www.google.com" onclick="window.open(this.href);return false; upisati "PIC12F629 datasheet" i skinuti sve o njemu...

Što dalje?
Reći ću kad budem znao, naravno u idućem postu... :)

Evo orginal Hex file kojeg cemo pokusati prevesti u nešti jednostavniji oblik. Najprije u assembler, a nakon toga u c-source:

Hex..... Rekao bih Intel Hex...

:10246200464C5549442050524F46494C4500464C33
||||||||||| CC->Checksum
|||||||||DD->Data
|||||||TT->Record Type
|||AAAA->Address
|LL->Record Length
:->Colon

Ovo o cemu pisem je intel hex file, pa sam zato postao ovaj hit iz kojeg cemo malo sortirati ovaj hex file, naravno u sljedećem postu, izbrisati ću nepotrebne stvari kao što su ova zadnja bytea hecksuna. colon i Record lenght....

Nemojte biti nestrpljivi. Ovako zahtjevan posao traži mir, tišinu noći i vrijeme. Ove noći vjerojatno nisu tihe. :D

Dekompajler ne moze. Disasembleri postoje, ima ga npr u icprog.
