How to make the 51 MCU a lights will shine while running water?-CodePudding

How can ability let the 51 single-chip led flashing while running water will have the most stupid method, due to space requirements, which bosses do want to a much less

CodePudding user response:

The space required? What is your original, to look at, just know how to streamline,

This is the original circulation,,,,,,,,

Haven't learned, not even at the very least of all can't? !

 
Void LedXm () 
{
The P2=0 XFF; 
} 
The main () 
{
Unisgend char x=0; 
While (1) 
{
Delay (5000); 
If (+ + x % 2) LedXm (); 
The else

Else if (x==14) {P2=0 xfe; X=0; } 
} 
}

CodePudding user response:

Above spelt wrong, correct and modify:

 
The main () 
{
Unsigend char x=0; 
While (1) 
{
Delay (5000); 
If (+ + x % 2) P2=0 XFF;; 
The else 
{
If (x==2) P2=0 XBF; 
Else if (x==4) P2=0 XDF; 
Else if (x==6) P2=0 xef; 
Else if (x==8) P2=0 xf7; 
Else if (x==10) P2=0 XFB; 
Else if (x==12) P2=0 XFD; 
Else if (x==14) {P2=0 xfe; X=0; } 
} 
}

refer to 6th floor wise men know already should good karma response:

 

The main () 
{
Unsigned char x=0; 
While (1) 
{
Delay (5000); 
If (+ + x % 2) P2=0 XFF;;

Else if (x==14) {P2=0 xfe; X=0; } 
} 
}

Don't understand,,,,, I am just the self-study

CodePudding user response:

Oh, that's good, for you are self-taught, you don't understand?
First you read the program downloaded to the chip operation is correct, verify,
So you give I modify program every sentence annotations, and see where you are I look not to know,
Much like a semicolon, correct the:

 

The main () 
{
Unsigned char x=0; 
While (1) 
{
Delay (5000); 
If (+ + x % 2) P2=0 XFF; 
The else 
{
If (x==2) P2=0 XBF; 
Else if (x==4) P2=0 XDF; 
Else if (x==6) P2=0 xef; 
Else if (x==8) P2=0 xf7; 
Else if (x==10) P2=0 XFB; 
Else if (x==12) P2=0 XFD; 
Else if (x==14) {P2=0 xfe; X=0; } 
} 
}

As you to directly modify the code, only be 7 leds, you carefully look at yourself, less copying code?

CodePudding user response:

You should be a state of 7 f, less optimized for the first time, still can continue to optimize, such as the use of array:

 
Void main () 
{
Unsigned char aa []={0 XFF, 0 x7f, 0 XBF, 0 XDF, 0 xef, 0 xf7, 0 XFB, 0 XFD, 0 xfe}, x=0; 
Unsigned int y=0; 
While (1) 
{
Y=20000; While (y -); 
If (+ + x % 2) P2=aa [0]; 
The else P2=aa [x/2]; 
If (x==16) x=0; 
} 
}

CodePudding user response:

If you further study can also use the existing left moves to the right function to achieve the effect, of course, is beyond the questions from you,

CodePudding user response:

Don't know if I understand right, a light, and then all the lights, then under a light... Cycle
#include
# define uchar unsigned char
# define uint unsigned int
uchar i;
Uchar led []={0 x7f, 0 XBF, 0 XDF, 0 xef, 0 xf7, 0 XFB, 0 XFD, 0 xfe};//the led flashing order
Void delay (uint t) {//delay
While (t -);
}
Void main () {
While (1) {//cycle flashing
for(i=0; i<8; I++) {
The P2=0 x00;//all of the lights will shine all
Delay (60000);
The P2=led [I];//in turn water flashing
Delay (60000);
}
}
}

CodePudding user response:

My understanding is all black, and then a light, all black again, next lights again, all black again,,,
All black a simple, direct, 0 XFF went, lighting parts with a 0, 7 1 byte, such as 0 x7f cyclic shift output, such as long as a simple cycle,
Modify the loop byte value, can reach different lighting effect, such as use 0 x77 cyclic shift output:
0111, 0111,
1011, 1011,
1101, 1101,
1110, 1110,
