Use 8051 to make a combination lock program! 200 points! Compilation or C will do

This is complicated, this kind of customized problem, it is recommended to spend money to solve, mixed here, will do are office workers, earn points with interest, do not rely on it to eat will not do, will only rely on a catalog on the Internet or not complete or even wrong ** over, cheating points of course, if you pay high enough, there will be someone here to contact you :) supplementary reply: you give a mailbox, I will send you a reference, if you are satisfied, you will give points, if you are not satisfied, you should serve the people.

You have to spend money to do this, how can you have time to fix this?

max equ 20h ;max unit.

ljmp main

mov max,@r0 ;The default is 30h maximum.

I can do it after I finish the test.

I'm not an expert.
