What PIC did you use for your design, as that seems like a good price for a kit, except for the shipping charges!

Yes, I use this design and swap some port to fit to my test board.
But mucop code didn't work for important code like, Play and skip that very complicate then you need to code by yourself or may be I miss something.
I use PIC16F877. and shipping charge is charge by cost, I check to Thai Post Office minimun charge calculate from 1 Kg. gross weight. If you done group by you can save cost of shipping.
And I also check to FEDEX and UPS also shipping charge is higher than my shipping cost about 10 -20 USD to USA.

Sincerely

Not to nitpick, but you can get audio out from an IDE cable.
Windows calls it digital CD audio, and basically it just reads the "files" on the CD and then the CPU decodes that to sound.

You can find the option to enable/disable this in your windows device manager, on the properties page for each cd-rom drive.

oh, and Very cool project too.

Dear all,

The data when CD Audio is played can output via IDE Interface.

if Cd-Rom play the CD Audio in Audio play mode the signal will output at audio out and headphone (at front panel).
if Cd-Rom play the Cd Audio in Digital play mode, Cd-Rom will read the data from CD Audio and store in the buffer, and then Cd-Rom will issue the interupt to the host to read the buffer. The maximun of data is 65536 Bytes in each interupt. Sometime may be less than 65536 Bytes. Then the host will read the data in Cd-Rom buffer after host read, Cd-Rom will delete the data in buffer and store new data.

When Host get the data from Cd-Rom, the data will be converted to audio signal via DAC. (if Cd-Rom play MP3 media, the data is decoded and converted to be audio signal.)

Default Hi Paradit

Hi there,

Your project seems very nice. I still havenít been able to get my Mucop circuit figured out and working properly. I was wondering if you had a working hex file for the original mucop. I can't seem to figure out what I'm doing wrong. If the original code is wrong of if I just assembled it in microchip incorrectly. I've triple checked the circuit and it looks okay.

I have everything on a push prototype board and the final will be on vero board. I want to try and run it in my moms car because the stereo is broken.

the Mucop 16F877 HEX file would help so much,

Thanks again.

Rick

Hi Rick
Like I have told you Mucop code have some bug for read TOC and play but some is work for open & close tray & stop. If your board can send command open or close tray that mean your board is ok.
Next you just debug for read TOC and play. If you cannot open or close tray that mean your board is have something wrong.
