IDE CD player through PIC - Electronic Circuits Projects Diagrams Free

wmmullaney · 27th January 2008, 06:27 PM

I have lots of very old cd drives(2x) laying around and I was wondering, is it posable to connect a pic to the drive and have buttons to 1. PLAY 2. SKIP FORWARD 3. SKIP BACK and 4. STOP. (Audio through the headphone port) I have looked in Google extensively, I need schematics and code for (PIC16F628A).

Thanks William

If they have the buttons and a headphone jack they most likely only need power to work.
It's a big effort otherwise for little gains.

I'm sorry, the drives have 1 button, what I meant is buttons connected to the pic.

wmmullaney · 27th January 2008, 06:37 PM

Can I do it with just a PIC or do I need other chips?

How good are your building and PIC programming skills? Are you comfortable with soldering and wiring point to point a PIC, pushbuttons and 40pin IDC connector? You have a spare PC power supply with +5 & +12?
A CD player is a cheap device now, you can even get them from Goodwill for almost nothing.

I'm okay at programming, and good at soldering, I have a 40 pin connector, and a power supply, the project is for pic programming skills and doing something with all my drives. I don't have any idea how to communicate with the drive, thats the problem, I need some code to look at.

From your previous posts I thought you were new at PIC programming.

Some neat links there futz

wmmullaney · 27th January 2008, 10:12 PM

Thank you, futz, that's not what I want. Those links connect to hard disks, I want a simple cd rom only connection.

Yes Bill, I am new, but I am catching on, I just need some simple instruction, and maybe a little code.

But those links ARE what you need to do it. The files on a CD are written in a file system, and you need to know how that system works before you can access them. I think it is a difficult project, and you might want to try accessing an SD or MMC card as a first step.

Presumably you want to create an audio CD player using a CD-ROM and a PIC?. There have been various examples on the net, but you need a larger device than a 16F628, the 16F877 is what you need.

However, the problem is that most of the sites no longer exist, so you need to do some serious googling!.

My personal favourite was

http://private.addcom.de/KeithWilson/Projects/

which also hosted the famous heart monitor, but it's long gone

I really wish I'd saved it while it weas there!.

Yes, I have experienced the same, and as a result try to archive all that is interesting. The problem is that I spend WAY more time on the web!

Does anyone just have some code? Does the PIC need to understand the file system? I thought it just commanded the cd player to play through the audio port.

An SD card reader would be harder, right?
