Hi Guys,
For those who got it working,
I’m doing a new program for the same chip to constantly scroll time & date like this:
“HH:MM:SS:CC DayOfWeek-DD/MM/YYYY”
using Darrel Taylor’s Elapsed Timer code, and my calendar program this should be quite easy now.

I have made a start today making a carrier board (because my hardware never had ICSP),
and wrote in support for DT Elapsed Timer to keep track of the counters dynamic.



It will be possible to set time & date with the original joystick, and have the program return the day of the week,
and keep track of real time from there without any additional modification, so long as the unit remains powered up.

This is a separate program. There was little room or RAM left in the Message scroller/Tetris/Snake code,
but it never had a real time clock, and was running from a software timer.
Cheers, Art.
