The prototype looks cool - Can you also include a picture of the underside of the build

I have added it to the Wiki.

very neat wiring -

Hello Art and all,

I downloaded the last 144_LED_V3.zip and I found some diferences in the schematics.
In 144LEDGAME-Schematic.pdf the keys (UP/DOW/LEFT/RIGHT) is wired by resistors to ground and active in High level.
In SchematicB.bmp UP/RIGHT is wired by resistors to VCC (active in Low level) and LEFT/DOWN is wired byr resistors to Ground (active in High level).
What is the correct schematic ?
I am building this hardware and would like to know the correct mode to work fine.
Other thing, in SchematicB.bmp the A.0 is wired only to resistor and UP key, but in SchematicA.bmp is wired to the led! What is the correct?

Thanks

So it’s 5 years to the month since making the three of them, and I have two left.
Funny this stuff hardly ever comes out once I’m done with them, but I got a new camera for Christmas so…

With regard to porta.0, after 5 yrs I’d do the same thing you should and look at what
the pin is used for. Four pins must be used for the joystick.

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.

Done Just got to clean it up as far as removing game artefacts and it would possibly be nicer
if the time/date message was variable length and verbose with words such as “Wednesday” and “March”.

Hi Art,

I would like to do it. My tetris game based in your project but using 2 (8x8) led matrix is working fine. Can you to post your last code?

Thanks
