有没有什么建议可以在C周期性地递减数组的方式 [英] Is there a way you can decrement an array in a periodic fashion in C

问题描述

我正在写一个code为一些在领导的节段1每五秒钟，以减少

在此刻我的实际code是这个

  FiveSecDelay + = 1;
如果（FiveSecDelay == 100）
{
count2--; //递减COUNT2为（uint32_t的x = 0; X 4;; X ++）//分裂计数到各个单独数字
{
NEW_VALUE [X] = COUNT2％10;
COUNT2 = COUNT2 / 10;
}为（uint32_t的I = 0; I＆下; 4;我+ +）
{Segment_Write（数字[I]，NEW_VALUE [I]）;将值分配给段
}
FiveSecDelay = 0;
}
 

使用程序器调用函数每毫秒的IM，理论上这应该工作为我所用同样的方法来分配一个值段，
什么情况是，我有8起始值，它应该有7,6,5,4等，直到0，但由于某种原因，从8变为42并保持有

我曾试图修复它，但都拿出短。

任何帮助将是巨大的。

感谢您

解决方案

 无效检查（）{
  静态int数组[] = {142}; //你为什么要使用一个数组吗？
  （*数组） - ;
}诠释主（）{
  而（真）
  {
    检查（）;
    usleep（5000）; //近似
  }
  返回0;
}
 

i'm writing a code for a number on a led segement to decrease by 1 every five seconds

my actual code at the moment is this

FiveSecDelay+=1;
if (FiveSecDelay ==100)
{
count2--; //decrement count2

for (uint32_t x = 0; x < 4; x++) //split count to to individual digits
{
new_value[x] = count2 % 10;
count2 = count2 / 10;
}

for (uint32_t i = 0; i < 4; i++)
{

Segment_Write(Digit[i],new_value[i]); assign  value to segments
}
FiveSecDelay =0;
}

im using a schedular to call a function every milisecond, in theory this supposed to work as i used the same technique to assign a value to the segments, what happens is that i have a starting value of 8, and it supposed to got 7,6,5,4 and so on till 0, but for some reason it goes from 8 to 42 and stays there

I had tried to fix it but have come up short.

Any help would be great

Thank you

解决方案

void check() {
  static int array[] = {142}; // why are you using an array here?
  (*array)--;
}

int main() {
  while(true)
  {
    check();
    usleep(5000); // approximate
  }
  return 0;
}
