SD card wire
i try to understand sd card connections to WIpy2.0 without expansion board
but i am confused about pinout and docs
in pinout i have
P8: DAT0, P23: SCLK and P4: CMD no external pull-up resistors are needed.
normally i will be connect as:
MOSI - P12 MISO - P11 SCK - P23 CS to "any pin"
how to really connect this spi device?
Finally got it - this was so simple :)
here is really good overview if someone start like i with SD playing
i reply myself ;-)
i see that i misunderstand doc - doc is about direct access to sd
by sd interface to dat0
Do i understand this now corectly? Can someone point me?
And more question in doc is:
and the current implementation only works in 1-bit mode
what limitation it create? And when it will be changed?
I am new in sd card interface.
I understand now 1-bit mode
there are also 4 bit mode - but 1 bit is enough for start playing
