Hi all
After a few hours of messing around with voltage dividers and logic level convertors, I've finally got my Duemilanove working with a plain SD card (not a shield or anything) using the following setup. Does anyone see a problem in terms of long term damage? It's not a setup I've seen used in guides/tutorials, so my instict tells me that it's not a great solution!
Arduino ---------------- SD card
MOSI(11) ---> 1k res ---> Data in
MISO(12) <--------------- Data out
CLK(13) ---> 1k res ---> Clock in
CS(10) ---> 1k res ---> CS
3.3V ---------------> VCC
GND ---------------> GND
This method is producing stable results. If anyone spots any issues with the setup above, please let me know!
Thanks for your time
Olly
