using a RTC in SF basic

I have a DS-1302 RTC module but how to use it?
I recall Jon Chandler made a vu meter clock but what he used for timing?
Am planning on a clock that has no hands, just LEDs but precision would be nice.
 
My clock would be like this 12 leds for hours
60 leds for minutes and one flashing at each second below the first hour then light hour with minutes lit and keep that to on for the hour while moving minutes around clock
 
I think I get your idea?
12 LEDs for hours, 60 LEDs for minutes and have the LED under the hour flashing.
say it's 3:18 so have the led below the 3 flashing while the LEDs indicating minutes continue on?
hopefully I understand this correctly
 
Aha I now get your point on only two LEDs.
Reading over post #221 and #222 I am a little confused about 2- hour LEDs and 12 LEDs for each minute?

am about ready to give up on this.
^^^^^^^ Go with your instinct on this. I'm afraid there's zero chance you're to make something useful given your difficulty understanding the hardware, software, and the visual display of time.

How does a flashing LED alter what I posted in post #378?

AM STILL TRYING TO COMPREND post#381

Time to throw this mess into the dumpster.

These comments pertain to the SAME post. In the dark (you know, at night with the lights turned off???), illuminating two LEDs (making them turn on???) provides no spacial reference (you can only see two dots and not the clock face, so you don't know what numbers the dots represent).

*shrug* Do what you want.... but you might want to consider if there's anybody left to help you with 20 more pages of writing software for you.
