Breathing light – using pcduino board

Posted by: ,

[vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”Introduction” tab_id=”1394073451-1-88″][vc_column_text]Breathing light is a status light really, also used for notification if a new message arrives or perhaps if you missed a phone call. you might want to consider turning it off if you are concerned with battery life as it does use a bit more, tho i am not sure if it is that significant.

I have published a post about breathing light- using arduino board, but use on pcduino ,need some modification.

#include"core.h"
#define SigPin 2
 
#define CYCLE 1500
 
void delay_us(int t)
{
  usleep(t);
}
 
void delay_ms(int t)
{
  while(--t){usleep(1000);}
}
 
void setup() {
  // put your setup code here, to run once:
  pinMode(SigPin,OUTPUT);
  digitalWrite(SigPin,LOW);
 
}
 
void loop() {
  int count;
  // put your main code here, to run repeatedly:
  digitalWrite(SigPin,LOW);
  delay_ms(600);
  for(count=1;count<CYCLE;count++)
  {
     digitalWrite(SigPin,HIGH);
     delay_us(count);
     digitalWrite(SigPin,LOW);
     delay_us(CYCLE-count);
  }
  digitalWrite(SigPin,HIGH);
  for(count=CYCLE-1;count>0;count--)
  {
    digitalWrite(SigPin,HIGH);
    delay_us(count);
    digitalWrite(SigPin,LOW);
   delay_us(CYCLE-count);
  }
  delay_ms(600);
}
