Re:Connecting 18f45k20 to a TSOP IR reciever
hi, what does it mean TSOP? It is for me a packaging style.
Otherwise, although I didn't use a 18f45k20, I think the INT hw is the same at all of the chips. Usually I pull up the pin for ex. 4,7k; If you attempt to use the chip in power saving HW it may be higher; when you try to use you TSOP is the INT line free from other switches, other hw? Does your button connect the INT pin (pulled up to VCC) to the GND, causing so the INT signal or connect the line to VCC6GND? Or how long is the TSOP signal? May be the multiple interrupt works on button press, and a single doesn't on TSOP signal
