playing pacman game on TV with atmel AT-TINY2313 and MEGA48

This system is using mega48 & 2 tiny2313s.

Mega48,whitch is the main cpu,controls coordinates of pac-man and monsters. This chip controls input buttons,too.

One tiny2313 displays the sprite charactors on NTSC signal.

Another tiny2313 displays background charactors on NTSC signal.

[nekosan0]

it's a great encouragement to me.

[nekosan0]

i 'm now trying to display color stuff on NTSC. please expect for my work!

[estlib]

nah, i meant it as a compliment! :D

[nekosan0]

so mega48 has a few memories that i cannot implement more logic.

mega88 or mega168 may have enough memories. i recommend using mega88 or mega168.

lol. pacman drifting! xD

I tried to write a information of site which is useful for me, but youtube system rejects the comment.

perhaps, prohibited symbol is in it. url and so on.

One TINY2313 outputs video signal on PB0 and sync signal on PD6,which is sprite.

Another TINY2313 outputs video signal on PB0,which is background.

And inputs H and V sync from INT0,INT1 to synchronize with sprite picture.

Simply,2 video signals are mixed with OR logic.

Mega48 outputs no video signal.

It outputs X and Y axis for sprite characters on UART.

2 TINY2313s input the axis data and make video signal.
