/*
Steps:
1. Edit pcmConfig.h
a: On Uno or non-mega boards, #define buffSize 128. May need to increase.
b: Uncomment #define ENABLE_RECORDING and #define BLOCK_COUNT 10000UL
2. Usage is as below. See https://github.com/TMRh20/TMRpcm/wiki/Advanced-Features#wiki-recording-audio for
additional informaiton.

SD card read/write
This example shows how to read and write data to and from an SD card file
The circuit:
SD card attached to SPI bus as follows:
** MOSI - pin 11
** MISO - pin 12
** CLK - pin 13
** CS - pin 4 (for MKRZero SD: SDCARD_SS_PIN)
