How to write key program?-CodePudding

As shown in figure, add four buttons, respectively, plus, minus, determine the function, how to write a program to implement S, KP, KI parameter values change??

CodePudding user response:

Is independent keyboard directly write judgment, there is a problem the code to see see! For example:

 
Sbit QiTin=P3 ^ 0;//stop button 
Void main () 
{
ZhongDuanSheZhi (); 
While (1) 
{
XianShi (); 
if(! QiTin) 
{
//XianShi (/* skillfully by 8 digital display shake */elimination); 
Unsigned char Yan_Shi=Js; 
If (TR0==0) {TR0=k=1; }//reset interrupt 
While (Js)==Yan_Shi XianShi ();//interrupt shaking, 
if(! QiTin) if (! K) TR0=k; The else k=0;//close the interrupt, after shaking, clear mark (use double judgment! K | |! TR0 & amp; & K) 
while(! QiTin) XianShi (/* press during display */); 
} 
} 
}

said look not to understand, ah ha ha ha

CodePudding user response:

Is an chestnuts, judgement is independent buttons, look not to understand the code is very normal, because it is other project extract has nothing to do with you, actually a little finishing note can understand:

 

Sbit QiTin=P3 ^ 0;//stop button 
Void main () 
{
While (1) 
{
if(! QiTin)//decision to press the button 
{
Unsigned char Yan_Shi=255; 
While (- Yan_Shi);//shaking, 
if(! QiTin)//determine whether is pressed again 
{what execution? } 
while(! QiTin);//wait for the button is released 
} 
} 
}

Usually it buttons

If want to copy the code have a plenty of places to copy, why to ask?
