Hello all. the code below is for RGB LED fading ect.. It works and up loads to attiny ok. the pinchange interrupt works as well BUT
I need it to be interrupted via SOFTWARE, but I can't do it. As this was written for a IR remote control, well pushing a button just won't do. And yes the IR remote works, As you can see It never comes out of the while loop as I don't know how to tell it that.
The code is from many sources and will list them when it works. So how do I set up for a SOFTWARE interrupt.??? Thanks, Ron.
