I've been working on an Arduino project.but I have to convert this code to pic microcontroller 12F683 in mplab ide.
CODE FUNCTIONALITY:
if input GP0 low (negative edge)output GP1 on for 2 sec and Off.
if input GP0 high (positive Edge)output GP1 is off .

My concerted PIC code toggle high to low for input is low .but i want only exceute once and exit loop.

I agree with twohats about posting code as text within code tags.

In this case - I have no intention of copying your code. It looks way to complicated to me.

I gave up on porting Arduino code long ago. Much preferred writing from scratch, else I always seems to end up with a hideous mess that was hard to debug.

Here is my attempt at a solution to the described problem, whilst ignoring the Arduino code:

Code:
// simple LED blink in response to button press

// I've been working on an Arduino project.but I have to convert this code to pic microcontroller 12F683 in mplab ide.

Thank you so much for your support ☺ HEXREADER I'm beginner in PIC controller . your code work fine.
