when I said adapter I meant something like this: http://prosoft-informatica.com/loja/images/micro_sd_adapter.jpg
A level converter is not needed since the MP3stick is running at 3.3V internally anyway.

About the VS1053 I don’t know, but firmware changes are required for sure, possibly some hardware changes as well.

With the yamppPod sound will not be better cause it uses a VS1033.

Btw, ARM programming is easy, an FT2232 is required to make an openOCD JTAG programmer. See the yammpPod reference documentation.

Can I use this MicroSD adapter?

Can I use vs1053? I will need to made firmware changes? Because this is never and cheaper chip.

You said you are sticking with the yamppPod. I do not have conditions to program arm micro controllers, you use them because they are faster? But do you have better sound quality?

Thank you,

Nikolaj

I have problems with LCD.I’ve got the mirror screen.Is problem

The VS1003 can be replaced, but firmware changes will be necessary.

Micro or mini SD cards will work, just use an adapter.

which can read Ogg Vorbis / MP3 / AAC / WMA / FLAC, so maybe you could upgrade your stick with that chip, I do not think it would be very hard.

And can I put other for example vs1003 instead of vs1011?

About sd card, there is some micro or mini sd, can I use that instead of big sd card?

Thank you,

Nikolaj
