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
and one last thing :
i read the article "adding custom parts to the device database"(http://www.keil.com/support/docs/1421.htm) and downloaded proper header file. But i am bad at soldering and having problems with board i designed. thats why i want to be sure with parameters that i set for uvision is correct.(and error is at assembly)
You seem to be a bit unlucky that they only have software for the snd1 and snd2 variantes.
"Please fill out and submit the form below to obtain the access and password to the restricted area. This will allow you to access up-to-date resources required to develop application using AT8xC51SND1C, AT8xC51SND2C or AT85C51SND3 devices."
www.atmel.com/.../mp3_registration_form.asp
Where did you find that link?
Andy Neil : really thanks for link. i filled it out and still waiting for them to sen password etc...( should it take so long to send it?) I hope i'll got some firmware and other helpful resources.
By the way, i mailed to atmel about resources and they told me, i had to purchase their development kit, for full firmware support! i am a student and i am not able to buy a $700 costing kit just for 2-3 simple firmware. do you have any other idea?
or will they send me a password for free instead of selling a kit? lets see:)
"simple firmware"
How do you know it's "simple" firmware?
If it's doing all the MP3 stuff, it'll be anything but simple! And it'll probably be subject to royalties.
Couldn't you use one of their other chips which does have the MP3 built in?
Or perhaps: www.vinculum.com/prd_vmusic1.html
www.atmel.com/.../tools.asp
Yes, I have already visited that page, but all references are for the SND1 or SND2 chips, and I didn't find any links that pops up a registration form. They either moved to other pages, or opened downloads of SND1/SND2 software or documentation.
In the menu, I found a link 'Support Center' and in the footer i found 'Contact'. However, I didn't find a link to the registration form in your previous post.
Hence, my question where you managed to locate that link.
lesson learned; investigate fully before selecting derivative. so, now, go buy a snd1 or a snd2
Erik
I'm not on a hunt for a SND1, SND2 or SND3. I was just curious where Andy managed to locate the link.
not addrssed to you, Per, just a comment on your post which reflect on the OP
But your claim was still valid anyway.
I did the mistake of selecting the wrong ARM derivative not too long ago. I went for an LPC2119 for a project without realizing that it is truly lousy at sending data as an SPI slave, requiring a change to an LPC2364. Since the Keil tools doesn't simulate the 2364 yet, I'm now waiting to see if the Keil update or the HW prototype will arrive first.
This is what I did:
Go to http://www.atmel.com/
Type "at85c51snd3b" into the 'Search' box on that page
The results give nothing really interesting: " href= "http://www.atmel.com/dyn/general/advanced_search_results.asp?device=1&tools=1&faqs=1&datasheets=1&appNotes=1&userGuides=1&software=1&press=1&articles=1&flyers=1&checkAll=1&checkAllReference=1&target=at85c51snd3"> www.atmel.com/.../advanced_search_results.asp
This one has the link to the Registration form!
So I removed the suffix and put that into the 'Search' box
just realize that quoted like this it makes no snese, please read "So I removed the suffix and put the basic name into the 'Search' box"
Yes, that makes a lot more snese!
" i am a student and i am not able to buy a $700 costing kit"
There is an important lesson to learn here!
Many things need to be considered when deciding what components to use in a proposed project, and one of them is the cost of the tools required.
If you're making a 1-off or low-volume product, this can be very significant; If you're making a high-volume product, then a few thousand dollars spent once at the start of the project to save a few pennies on every one of millions of units sold obviously makes sense!
Undoubtedly, Atmel are aiming at the high-volume market for this.
Even for low-volume commercial projects, Engineering design time is expensive - and $700 doesn't buy many hours!
