[MOVED] Falling edge detection code for PIC16F877A and MikroC Compiler

[Elektro Garage]

I am using the Counter on Button and Count on depressing the button, which means on falling edge. After lots of searching and different experiments, I have done it.
MikroC code chunk:
while(1)
{// UP counting using Falling Edge
led=0;
if(up==1){up_pr++;}
if(up==0 && up_pr>=1){count++;led=1;Delay_ms(100);up_pr=0;}

Hi,

almost any microcontroller can count falling edge events without the use of software.
Much faster than the software can do. And the microcontroler can in parallel perform other tasks like communication, display...

Besides this... what is your question?
