Any esitmates on when these will be back in stock?
about 8 years ago
Has anyone gotten these to work with an Arduino? I've been able to hook up the breakout board to the Arduino via a 74LVC245. I can read and write registers with SCI and initiate a sine test with SDI but when I send MP3 data via SDI it pretty much just locks up. Sometimes I'll get something that sounds like its trying to decode but its usually garbled or just silence. It takes a power recycle to get the chip to respond again. Here's what I've done in software:
Set the clock to 0x9800 like the data sheet says for a 12.288 Xtal
SPI is MSBFIRST, SPI_CLOCK_DIV8, SPI_MODE0
Set mode to SDINEW
Drop CS low for SCI enable and drop XDCS (BSYNC) low for SDI enable.
My guess is it has something to do with byte syncing for SDI. But the 8 byte SDI tests sequences work. I check DREQ to make sure its high before sending but I rarely see it go low.
If anyone has had any luck I'd love to hear what you did.
