Retrieve the last error code and clears it. To analyse the error reason, take a look also at the files sd_l1.h and sd_l2.h of the library to find the meaning of the code.
= FAQ =
== It does not compile ==
* Are you using the latest version of Arduino IDE?
** SimpleSDAudio_V1.00 need at least V1.0.1 of Arduino IDE.
** SimpleSDAudio_V1.01 need at least V1.0 of Arduino IDE (remove complete block with !Serial from examples when using with Arduino IDE V1.0).
== SdPlay.init fails ==
* Have you selected the correct CS pin for your SD-card? Uncomment the line <pre>// SdPlay.setSDCSPin(10);</pre> in the examples and enter correct pin number here.
* Your SD shield may be crap and SD communication is only possible with limited speed. Try commenting the line <pre>SPSR |= (1 << SPI2X);</pre> in function ''SD_L0_SpiSetHighSpeed()''. If this doesn't help, comment out also the first line and try again. If then init works you have a bad SD card shield.
