I hope this is not a dumb (or already answered) question: does it work also with a 2*20 LCD? With the same firmware I mean.

Of course, Yes....🙂

But You need to re-write & re-compile the program to adjust display message position from 2*16 to 2*20

or

If you don't mind the display message position...

Remember! Check the pin assignment at first...

Hi everyone

I am trying find the I2S or EIAJ from a Creative Infra 48X CD-ROM drive. I have located the integrated server, decoder and DAC IC, Toshiba TC9450AF.

I have a schematic of a Samsung CD-ROM drive that has the same IC, TC9450AF. Reading this, I found the following information:

Pin 2: BCK
Pin 3: SDATA
Pin 4: SPDIF
Pin 98: LRCK

I guess that Pin 2, 3 and 98 are the ones to be used. However there are some other notes that make me a bit confused:

Another pin is marked as DATA
Several pins are marked ??CK

Could some one tell me if Pin 2, 3 and 98 are the correct pins to used.

As this IC is made by Toshiba, I think it will give EIAJ format. any other ideas?

I would like to have the datasheet of this IC but couldn't find it.

I would be grateful if some one can help me on this.

Thanks

hi guys, this thread is very interesting and...BIG! 😀
but i'll be very grateful if someone will place a post with IDE commands, timing, or somewhat useful to build our own controller without buying a kit!i have found schematics where several microcontrollers are used, but have no idea about "the language" to use to speak to the cdrom...and tell it what to do!
thanx in advance!

Hi,quantran,

I see that you have the schematic of TC9450, could you pls send it to me by email or post it on here?
I want to refit my old 40X CDROM, I found TC9450 in it, but I can not find any DATASHEET of TC9450 on internet, thanks so much!!!

woa..found a couple of pages before... the lucifix zip file, it has all inside!...anyone tested it?and...it has an ir receiver but wich remote do i have to use??
Click to expand...
🙂 Sorry I forgot to mention that... the remote control protocol supported by the control kit is RC5. Any Philips-compatible cd-player remote should work.
For advanced users here are all RC5 codes accepted by the uC:

#define System_Address 20

#define RC5_ST_BY 12
#define RC5_EJECT 45
#define RC5_SCAN_NORMAL 43
#define RC5_TIME 11
#define RC5_SCAN_FAST 47
#define RC5_FFWD 52
#define RC5_REW 50
#define RC5_RANDOM 28
#define RC5_NEXT 32
#define RC5_PREVIOUS 33
#define RC5_REPEAT 29
#define RC5_PAUSE 48
#define RC5_STOP 54
#define RC5_PLAY 53

Set your Universal remote control accordingly!
Enjoy!

Hi everone,

This forum seem to be very interesting. I have done an ATAPI interface using 8051 pro some years before and was quite unhappy with the capacity of the discs. Now im trying to make hard disks replace the CD drive, which is available at cheap rates and has higher capacities. Also a USB interface is made to the HD for copying songs to the HD easily.

Hello ,

I have a Plextor PX 116A and i would like to use it like a DIY CD drive .
But there is no pdif output connector !!!!!!!! :dunno:

I looked at inside and the circuit is the PANASONIC
MN 103S71F :hot:

Fo the moment i have not found the datasheet on the net ...:bawling:

So if someone have this datasheet and it would be very sympatique 😎

Best regards

Serge

i'm intersted, but do I need to read this whole thread to start? anyone care to post a summary?

Also, I'd be interested in using a cdrom that is a slot load, or doesn't use a traditional tray... any ideas?

Provided the drive is IDE, you should be able to use it with most of these kits.

I've successfully used about 10 different drives (including a slot loading Pioneer 24X CD-ROM) and haven't had any issues.

The drives I had problems with were either CD-RW, or DVD-ROM drives.
