Looking for a fresh set of eye's

[mackrackit]

OOPPS, I was seeing another PIC and not a shift reg.

All on the breadboard, ready to go

Changed the dp circuit to reflect the other seg's.

Looking at the layout. I can now use the Pic of my choice.

Just dont know which to use.

I guess it depends on whether I can find a quick test code or an actual clock code to run on this.

Anyone have a 3 wire clock code to try using one of the following Pic's?

16F627A
16F628
16C54
18F4620
18F4525

Here is the latest schem for my project.

I'm lost and bewildered on the coding part.
Hex, ASM, C, Basic, Etc.. I have no clue where to start.

The Schem is based on a 3 wire SPI setup, You can use almost any Pic that will handle this.

Would anyone have a test code sample, Using a 16F627A that will interface with the 595's and light up a single segment in order from a-g and dp of each digit and then move on to the next digit. ( I have several 16F627A's I can toast learning this code on)

I think Basic would be the easiest for me to understand. I understand what it does, why it does it, but not HOW..

Any help at this point would be greatly appreciated and possibly save my sanity. So far from just an idea to a circuit has taken just over 2 months, I'm in no rush to just make this thing and move on.. this is my learning "Pic" project.

Just need a boost on this.

Cheers
Steve

Just for some idea on how complex a project like this can actually be:

And I think you'd be much better off working your way up to it.
Have you made 'blinky' yet? (that's what we commonly call the PIC controlled blinking LED)

We (we being those that have been at it for awhile) have all said it before, and will probably say it again, if you don't start small and work up to whatever it is you're hoping to accomplish in the end, you'll give up and have X dollars of hardware that'll never get used again because you're sick of failing.

The RX part will never work, there's a missing Pull-up in there.

Easier to use a ULN chip and skip the Shift register for a single display. For more than 1, still possible to use I2C I/O extender, or even some dedicated led drivers from Maxims.

I doubt that everything would fit in a 16C54 or 16F627. Maybe possible with a 16F628.

How many different 7 segments display you plan yo use?
