New library for PWM playback from SD cards: SimpleSDAudio

Using Arduino Audio
152

Hi, it seems that is still something wrong, either with wiring or something else.

Regarding post 145: If you build your voltage dividers correctly and assuming that you are not driving MISO as output you should not measure more than 3.3 - 3.6v anywhere on the SD card.

Please also check:

  1. You use a SD or SDHC card, but not SDXC. Old MMC cards may work - not tested.
  2. You use Arduino IDE 1.0 or up to 1.0.3, but not 1.5 (the beta version only for Due)
  3. If you use a ATmega328 based Arduino, even a clone, you should use an unpatched Arduino IDE and program the Arduino using one of the boards-setting that came already with the standard IDE.
  4. If all is ok, check if your Arduino is still working on all ports used by the SD card. Set ports to output and high and you should measure 3.3v at appropriate SD pins.
