nice one ....actually i was looking for an idea for my school project using 68hc11 µc i think i ll go for tic tac toe too XD

[cedtlab]

We made a new version of this game and it is implemented with just a 20 pin AVT Micro (AT Tiny861) instead of two-processor implementation as seen in this video.

hi again :

great job for the 20 pins trick ...today i talked to my groupmates about your idea and discussed the plan ...but we want it with one µc ...wich seems impossibl for the moment because out thinking were like that :

- 9 bi-color leds so 18 pins to control all of them

- two 7-segment displays so + 14 pins

- + 2 pins for the status led tht s make 34 outs we should have !!

i ll keep you up with anynews

[cedtlab]

20-pin uC has max 18 I/O pins. Some even have only 15. But even with 15, its possible:

1. 9 bi-color LEDs = 18 LEDs + 2 status LEDs = 20 LEDs. 20 LEDs can be controlled with just 5 I/O pins using Charlieplexing.

2. Two 7-segment displays can be controlled with 8 pins. That still leaves you with 2 pins. Which you will require to connect a few switches to play the game. Use the other pins for LEDs as output pins and use the 2 left over pins as input and connect as many switches as you want!

we cancled the score displays and replace them with just 2 leds in the other hand we will place 4 directional bottons and a "validation" botton for EACH player so no more struggling about bottons :D so we have : 18 outs for game leds + 4 outs for the 2 status leds = 22 outs 8 in's for the directional bottons + 2 in's for the validation bottons = 10 in's Do you think that's gonna work ??! and for the assembly , can i learn the main fonctions in about 20 days or less ? thank you

[cedtlab]

Oh yes. For a first project its always good to keep it nice and simple. It would work just fine. And 20 days should be more than enough. Goodluck!

what the fuck happen to paper and pencil

[danielpotter19912]

you are just jealous *g*

[mayankkgrover]

@A7lan7is then that ur problem!!

[POYOSITO]

Hi!!! if you can make a tutorial to do this game i would be thank full with u! i need a proyect to mi class Digital Circuits and i can see than these work very well... so i'll woundering if can u text me back, so u can teach me how to do that if u don't mind... and if u can't it's ok...i'll understand...

[A7lan7is]

I hate your accent

[bakugan901]

hey u sound like an indian women

[KiriouSs]

hehe this way you can keep the same paper over ad over again:P

[gun20]

it is easier on a piece of paper....but good job! :)

[bloggyboy91]

very nice guys !! I've made a zero cross game in which computer plays agaist user using webcam..check it out !!!

me quedo con la hoja lapiz y papel ... y adarle xP

i let you say stuff like that when you can actually spell pencil.

why are you such a douche? leadingham3000. obviously he has an interest in electronics so let it be.

[xzibit2313]

care to share the schematic ??

did you make it all yourself

how old are you?

and what language did you program it in
