hello

I am a newbie at microprocessor

I don't know how do a value over 255 times a value over 255 in asm laguage. So I type it in C language and compile it then read the disassembly sentence by sentence. But it beat me from very beginning. Some sentences are missing.
eg:
C:0x000C 02004A LJMP C:004A
...Then I went to fine 004A, but there was 004b following the 0049. There is no 004A.
So I can't follow its thought.
Why some senteces/addresses are missing at disassembly? I use Keil uVision2.


PS:Any article can tell how to mix C and ASM. I want to use them at the same program so often.

Thank you very very much.
 

Hi,

I used assembly for programming microcontrollers for some time, however now I use C since it is much easier and is not specific to the architecture. But using disassembly to understand assembly is a new subject for me actually.

However, concerning mixing C and Assembly in keil uvisoin2. you can do it very simply. You can find the details in these page
