Hello,
I'm trying to interface arduino uC to a microSD card thru pin 8-13 and GND.
I have been googling and i found this post, ladyada's code[1] based on roland's code[2] and some arduino's vendor code[3].
I have not been able to use SD card yet. The closest i got it is with this post and ladyada's code, but i can not initialize correctly the SD card.
As i read in this post, some people is having same issues, did you resolve it?
I'll be waisting some time on this and kick it, if somebody wants to join, it is welcome.
(I can not post active links)

send q to stop sampling
