ultimate source

USB mass storage for Ultimate Source project - brainstorming end

I found two devices that could act as an USB Host, stream data through SPI and meet the speed criteria of minimum 200KB/sec needed for 44.1/16

1. Vinculum's FTDI-VDRIVE2
Pros: is always SPI Slave, has relative simple command set for FAT32 accessing, dev time seems low. It's cheap, ~25euro
Cons: support says it can read continuous 200KB/sec, only 10% more from the required transfer rate might not be enough. It could be possible with low fragmentation drives and very optimized code. This transfer rate would be enough for 44.1/16 only

2. FEZ Domino
Pros: supports says the SPI can give ideally 3MB/sec, so we could expect to handle ~700KB/sec enough for 96/24. It runs .NetMF, so development is easy
Cons: it acts as SPI master always thus the data clocking is difficult; some kind of protocol should be implemented between the slave dsPIC33 and FEZ and extensive buffering on the dsPIC side... development time needed unknown

These are just information. I'm still researching FEZ Domino as it would be nice to have 96/24. If I decide on one I will open a new thread for it.
Anyway, Koon's board will be needed for any of the above, however, in case of 48/96Khz a second XO is needed (easily solvable with a piggy back board and a relay)

Looks like very good solution for "all in one" player :

ADI ADSP BF592 Blackfin Ultra Low Cost 800 MMACs DSP : Electronics News from ElectronicSpecifier

ADSP-BF592 | Low Cost Blackfin with Optimized Peripheral Set for Industrial and General Purpose Applications | Blackfin Processors | Embedded Processing and DSP | Analog Devices

Two I2S and SPI , 400Mhz . Nice one for a new project , what do you think ?

I was looking at doing something with these blackfin chips a while back, but I gave up.

Came across this sd card player board - has ipod docking compat. and i2s out

Music Shield | Australian Robotics

Looks like an interesting project. Might try "porting" it to dsPIC33FJ64GP802 that I'm working with at the moment, see if I can get it to drive the onboard DACs direct. We also have UDA1355 S/PDIF codecs at work, can do I2S in for analog and/or S/PDIF out. Sounds like an interesting combo to play with.

I'm waiting 32GB SDHC card from Amazon....

an interval I'm thinking about next board, after FAT32 implementation.

4in x 5in 4 layer (ExpressPCB 4 layer ProtoPro spec)
ExpressPCB - Free PCB layout software - Low cost circuit boards - Top quality PCB manufacturing
16x2 display, 3.3V
Lithium Battery 860mAh for portability
USB-miniB for CHARGE ONLY (note)
SD card holder, dsPIC 100pin (30KB memory)
11.288MHz, dedicated regulator, MCLK buffer
I2S output
Toslink SPDIF optical output
pad for COAX SPDIF output
Play/Pause/Stop/FF/PREV CD(folder)FF / Prev keys

Note: There are no USB2.0 - SDHC writer chip on sale at Digikey etc,
so I will not try USB file management at this version.
Just pull SDHC - and use PC's SD slot or SD reader.

how much it costs and I am in Indonesia where I can buy?

you cannot buy afaik, you can only make it, i presume you followed my link. why have you made 3 posts above saying the same thing? we understood the first time

it is a DIY project with the emphasis on the Yourself part, there is not, nor has there ever been a kit or commercial PCB, formal instruction manual or forfmal support network, if you are looking for this, i'm afraid you will be disappointed
