CDDA player

[Antony]

Hey,

I would like to do a CDDA player.
For that, I made a yampp3/usb (hardware) with ATMEGA161.  I suppress the part USB, the part RS-232 and the part VS1001 in my hardware. Therefore, the port D in my atmega161 is connected at the "KEYS" in PD3 and at RAM 62256 (WR and RD) in PD6 and PD7. The other pins of the port D are no connected.

For the software, I programm my ATMEGA with "yampp-3/usb CDROM firmware with CDDA".

But nothing work. I verify all the connections, all the bus, all the composant and all the harware. But The LCD and the CD-rom don't work.

Have you got an idee for my problem.

THANKS :  -/

I would like to used an ASUS 52X. Is it a problem?

Add the RS232 parts and run the test programs.
Then come back with more information.
