HELP! (PIC16F84A Digital Clock)

[Buck Converter]

I need help finding a RELIABLE schematic and code for a PIC16F84A based digital clock. I'm at my witts end, and have rerached the point of no return.....

Why does it have to be a PIC16F84A, which is an obsolete PIC?

Here, for instance, is one with a PIC16f628, you could use a PIC16f628A which is a more recent PIC that is more powerful and costs 1/2 of what a PIC16f84A costs.

Just what I'm looking for, but where is the 4th hour display? it only shows 3 digits?

 

[BobK]

He is using a 3 1/2 digit display since the fourth digit can only be a 1. It could be easily modified to use 4 full digits.
