如何使用并行端口制作LED灯 [英] How to make LED light using parallel port

问题描述

这里有人可以将这个C语言代码转换为ASsembly语言代码吗？

Can Someone here Than can Covert this C language code to ASsembly language code ??

#include<stdio.h>
#include<ioports.h>

/* NOTE:
Don't forget to add the -l ioports option under Tools->Compiler options
This will add the ioport interface library

OR 

from the command line:
        
        gcc binary.c -l ioports -o binary.exe
*/


/* Define which port to write to */
#define IO_PORT 0x378

main(void)
{
   int num;
   char instr[25];
   
   printf("press ctrl-C to stop\n\n");
   
   /* Place port into standard output mode */
   outb(IO_PORT+2, inb(IO_PORT+2) & ~32);
   
   while (1) {

      printf("Enter a number (prefix with 0x for hex) :");
      fgets(instr, sizeof(instr), stdin);
      
      /* Jump out of loop if q entered */
      if (toupper(instr[0]) == 'Q')
         break;
         
      sscanf(instr, "%i", &num);
      
      /* now output it to the port */
      outb(IO_PORT, num);  /* write value to port */
      
   }      
    
   return(0);     
}

推荐答案

如果你想要一个备忘单，在GCC上使用 -S 选项，例如 gcc -S binary.c 。这会产生 binary.s 文件。学习阅读 binary.s 文件的内容，然后进入汇编语言。



一旦你了解阅读并理解你需要自己编写的功能，你已经准备好学习写作了。

没有人可以从你那里承担负担。

If you want a "cheat sheet", use the -S option on GCC, e.g. gcc -S binary.c. This results in a binary.s file. Learn to read the content of that binary.s file and you will get into assembly language.

Once you understand reading this and isolate the function you need to write yourself, you are ready to learn writing it.
No one can take that burden from you.
