Urgent for C5 1 MCU 12 lamp to run the 4-digit digital tube control program, which requires both the digital tube and the lamp to be on, and it is better to have comments.

I don't know if your digital tube is negative. If it is * * * positive, I will change it for you.

The program code is as follows, you can download it to your single-chip computer to test it.

# include & ltreg 5 1 . h & gt；

sbit shmag _ 0 1 = p0^0；

sbit shmag _ 02 = p0^ 1；

sbit shmag _ 03 = p0^2；

sbit shmag _ 04 = p0^3；
