I am attempting to interface a Pro Micro 3.3V with a SD card using Arduino 1.0. Since the voltage level is 3.3V I do not have a voltage level converter and have wired the SD card directly up to the SPI port with SS pin tied to the SD card CS. This setup has worked for me with other AVR processors running @ 3.3V. Before I've used the Arduino development platform (v22) and had no difficulties; however, with the Leonardo setup and Arduino 1.0, the application I created (which is basically the test read/write application) fails to initialize the card.
My question is has anyone been able to successfully initialize and read/write to a SD card with the Pro Micro series (32U4) of devices AND Arduino 1.0 using the included SD library? If so, any tips or suggestions would be appreciated.
