implementing at85c51snd3b on keil

hello i am really a newbie(an electronics student) and i have to use at85c51snd3b but i dont know how to set uvision for it. there is no proper target in device database. But uVision tells it supports.

actually i am supposed to built an mp3 player. i'll really appreciate any help for it. (at85c51snd3b1 does not include an built in mp3 decoder and i have to implement it by my own way. but again i have no idea about mp3 decoding(but i know about DSPs and microcontroller, and i am good at programming)

thx a lot for any help

  • hold on... hold on a second. "any help will be appreciated" doesnt mean "i need a whole project". First of all i read all manuals and documents related with this product. I wish you wouldnt say there is a mp3 decoder in it, with just looking first page. because actually this product is an dsp processor. its ancestors hold a built -in hardwired mp3 decoder but this! it implements all job by firmware.(if you dont believe just search keyword "decoder" on datasheet.) Here what it states :

    "Prior to enable the digital audio processor by setting the DAPEN bit in APCON1(1), the C51 must load the processor codec firmware which is the stream decoder or encoder."

    actually (i think) this product is a brandly new. and have not much resources(a programmer,a datasheet and a 2 application notes about high speed usb etc...but no firmware or related user guide.) and believe me i am doing my best.

    Maybe i am wrong but those are what i understand from datasheet
