Hello I'll try to answer your questions:
It is not clear from your question at what point are you NOW?
Do you have a 5150? (No I'm using a Nokia 5110)
Do you have the interface specs (pinout, voltage, timing, etc.) (yes I have read the data sheet, and all
Of my timings and voltages correct)
Do you have a working electronic circuit driving the display? (Yes my Nokia 5110 LCD is working and displaying data from the RTC but not in a readable form)
Do you have the software drivers to operate the interface circuit?(yes I am using spi for RTC and the display)
Do you have the software to create patterns on the display? (No I do not that's my problem, I need some sort of lookup table to display the time coming from the RTC)
Thanks Lester
A very basic Google search revealed that all of those items are available from multiple sources.
I don't really understand your question as you have stated it.
