PIC16F877 Audio CD Player. 100% working guaranteed

[pasanlaksiri]

I actually looking for some thing like this for years. Then i found one but it didn't go so well.
Then some guy debug and improved it and post it in here.

http://www.diyaudio.com/forums/showthread.php?s=&threadid=30529&perpage=10&highlight=cdrom&pagenumber=1

So i build it yesterday. Woow its worked perfectly. Now im soooo happy. So i think to share it with u guys.

LCD Details

Total Song Total Time Time of current track
Track No. Total Elapse Time Repeat Status

Player Features:

*Pause On/Off
*Stop/Play
*Eject
*Skip next Song
*Backward Previous Song
*Auto Repeat On/Off
*Can Choose Track No. by press No. on Remote Control

If u visit to that Original Link u can see there is a Two versions. Free and Comercial. If u want u can buy that coding for $7 from him.

BTW i build the free version. Coz of that That REMOTE CONTROLING part is Disabled

thanks for sharing cool.

[paranz]

thats nice. thanx

[RaffT]

thanks for sharing that here... Have also been looking for a project similar to that... another PROJECT in my TO DO list

[glutnix_neo]

cool kasam na rin yan sa todo list ko,buti hindi na mahihirapan magresearch,hehehe,

nice one pasanlaksiri..

that's nice.

in english:

that a cool project, i will add that in my TODO list. Im glad you posted it so i dont have to waste time making research

Oh boy. Ur like me i also hv a TODO list.

Dude can u share with me ur TODO LIST. I will be nice and fun too

hindi kaya ang basis nito yung ginamit yung CD-ROM para sa answering system sa PBX.

trans: was the original circuit based on the PBX that used the CD-ROM as answering system in a PBX?

[marcelino]

this is cool! i have to add this to my TODO list also.

does it only play audio CDs? hopefully someone adds an MP3 playing capability to the program. I believe this will require different programming and F877 may not be sufficient (I don't know!) I may have already read similar project like this. That was 7 years ago. unfortunately, it din't add to my TODO list since i don't have yet an idea of how to deal with MCUs...

is this an english zone? hehehe

foreigner kasi siya.

I believe there are already ASIC's made to decope MP3 files. can't remember it's exact name but it was used on an AVR Butterfly project to play MP3 files.

oh.. i see.

nwei, what was in my mind is to review the decoding routines for mp3s and apply it to MCUs. by this, we can further understand MP3s or other related audio compressions. i don't know if it worth to review MP3s. heheeh

[rdpzycho]

most of the self coded MP3 decoding MCU's were using ARM. based on them, it requires lots of processing power and memory (RAM usage were in the kB range).

perhaps dsPIC's can also handle them.

well at least what i believed was correct . F877 can't handle MP3decoding. hehehe
OT!!!

but this is a very nice project...

Another version of this player i recently post but not personally tested....maybe someone can try this. I'm in the phase or sourcing the parts...

since CD-ROM and Compact Flash share a common interface, perhaps this can also be done for Compact Flash drives. then a portable version could be made.

the trouble of utilizing flash memory is that you may have to convert it to wav files first but i think this is very much doable. it will also provides a convenience to user since most of us does not prefer CD as media over flash memories.
This would be a very nice innovation.

of course the popular flash drive would be used in this case in which we will be opt to use a usb interface. hehehe
and eventually this will look like an audio player in the market that have a usb interface for MP3s. heheheh (i first saw this on a sony component)

Yes this one only can play Audio CDs

If u r trying to make PIC MP3 Player. Use MP3 Decoding Chips.
