Manually compile and link to generate the hex file of c51

This is purely a personal preference. The system UI is getting better and better now, but I still like the command line inexplicably, it's a kind of nostalgia.

Once again, this is just a personal hobby.

Although it is manually compiled, it still requires a Keil installed environment.

detailed steps:

1. Use Notepad or Notepad++ to write super simple code

For example:

#include

sbit L1 = P1^2;

void main()

{

     L1 = 0;

     while(1);

}

Save as test.c

It is best to build this source code into the keilC51BIN directory to avoid typing too many paths.

2. Enter the keil installation directory keilC51BIN in cmd

Execute the following command:

c51x test.c

lx51 test.obj TO test.abs

ohx51 test.abs   

Note that "ohx51" is the letter "o". Then check if there is a hex file in the current directory.

I tested the running light with STC89C52 successfully. I didn't try the big one, so I don't know how it works.

There are also operations for multiple files.

Source code is required. Assume there are two source code files example.c and sexample.c. Use c51x to generate obj files respectively.

The operation is:

c51x example.c

c51xsexample.c

Then use lx51. This is the key, because there are two files. There are also people on the Internet who complained about the inconvenience of Keil code editing and turned to VS2010 to write C51 code, but after configuration, they found that they could only compile one file and could not compile multiple files. This is the key. The configuration method I found on the Internet wrote the parameters of lx51 as follows:

$(ItemDir)$(ItemFileName).obj TO $(ItemDir)$(ItemFileName).abs

It seems to be OK, but it is probably because when passing parameters, not all obj file names were passed, so the problem occurred. You can try it manually. The operation is as follows:

lx51 example.obj sexample.obj To hello.abs

The last step is naturally to generate a hex file

ohx51 hello.abs

Try burning it :)
