  • implemented 1.0.1 into repo

1.02.14

  • implemented sdfatlib20131225 into repo

1.02.13

  • ifdef'ed out space for Leonardo's less program space.
  • made FilePlayer.ino more equal to that of MP3Shield_Library_Demo.ino

1.02.12

  • implemented sdfatlib20130629 into repo
  • removed unused code in FilePlayer.ino

1.02.11

  • Added support for Bass Enhancer VSBE

1.02.10

  • implemented sdfatlib20130313 into repo
  • updated VLSI Patches and Plugins.
  • fixed MP3ButtonPlayer2.ino example

1.02.09

  • added demo of button using button2.h library for debounce (see gisthub for improved button.h library)

1.02.08

  • added support for BareTouch pinout in config

1.02.07

  • added SendSingleMIDInote() that sends a MIDI beep. It will suspend current playing stream to send beep and then resume prior stream

1.02.06

  • added PERF_MON_PIN to enable allowing measurement of the CPU utilization and description of performance document

1.02.05

  • implemented sdfatlib20130629 into repo
    • minor corrects of SdFatUtil's FreeRam() reporting correct value.

1.02.04

  • improved SPI handling to guard against other SPI effects and speed
  • increased SPI rate for 16Mg vs 8Mg FCPU, as to read at correct speeds.

1.02.03

  • cleared interrupt during refill, if used. As to allow others. Such as timer0 was falling behind during the SdCard track.read().
  • Along with displaying current second at command prompt, for verifying time.

1.02.02

  • updated SdFatLib to sdfatlib20130313
  • added const to PROGMEM uint16_t bitrate_table for avr-gcc 4.7.2 compatibility
  • added ASCII range check to strip off non-ASCII, such as CR or LF, on FilePlayer.ino

1.02.01

  • added new example FilePlayer.ino, more elaborate command to play all files.
  • updated ram usage prints.
  • added missing MinimumSerial files from new SdFatLib

1.02.00

  • Roll up of all below changes for release

1.01.01

  • added getState() as to report other possible states, such as paused but playing.
    • added check to enableRefill()
  • added GetDifferentialOutput() and SetDifferentialOutput() feature to change the output, as to create a differential left/right output with a maximum output of 3V.
  • changed case of get.. and set.. functions all to lower case for consistency.
  • added VU meter support
  • added chdir("/") to example and fixed enableTestSineWave freq
  • Added skip, pauseMusic, resumeMusic and optional time offset to playMP3 along with examples.
  • corrected typo's in Differential and initialized.
  • updated test for mp3
  • added example WebPlayer.ino
  • sdfatlib20121219 replaced sdfatlib20120719

1.01.00

  • changed sdFat to be instanced from INO file using sd.begin() for simpler use.
  • added end() feature to put VS10xx into low power mode, along with corresponding checks.

1.00.02

  • Fixed SkipTo() feature and added menu command.

1.00.01

  • added support for Leonardo's interrupt switching and documentation.
  • added documentation Gravitech's MP3-4NANO
  • added Mono Mode and menu command, because of Nano's single speaker.
  • added ADMixerLoad and ADMixerVol features

1.00.00

  • formatted comments with Doxygen markdown.
  • rearranged location of functions for organizing documentation
  • extracted read of MP3 files bit-rate to member function.
  • cleaned up some type casting.
  • added history.md and license files
  • improved tolerance of bit-rate read from mp3 file header.
  • moved setting Playing to true after file is opened and bitrate is read.

0.09.00

  • Added SFEMP3ShieldConfig.h to support alternate hardware for none INT0 DREQ based cards and or Shields. By using Timers, or software pollings, such as with Mega and Seediunos.

0.08.00

  • moved MP3 functions into class and cleaned up syntax
  • finished bitrate_table[] table with last row, that was missed.
  • added "d" command to print directory of SdCard
  • added "+/-" command to change volume by 1.0 dB
  • added print of FreeRam() to show amount of static RAM available.
  • save 220 bytes by using F() function to put strings into Flash and not use RAM:
  • i.e. Serial.Print(F("Hello)");
  • note: FreeRam() is supplied with SdFatUtil.h

0.07.03

  • Added apply patch/plugins from SdCard file to VS1xxx.

0.07.02

  • Added quick check if trackname is mp3 extension.

0.07.01
