Re: 16F84A LED 4MHZ One Second Delay Not Blinking
That did it.
Yes.We are using board with 2 pin crystal socket and 22pf cap's soldered on.Right now 4MHZ crystal is in there.
I looked up that 20 address. That's for 'better' 16F84's. 16F818 and 16F628A.18 pin PIC's.
Thought it sounded familiar.
Book author says 818 is his favorite.Most of programs in book are for 16F84.He says it is most popular.
