Features• Easy to use memory card interface• Supports MMC/SD/SDHC• Plays MP3, PCM WAV, and IMA ADPCM WAV files• MP3 playback control via serial or parallel interface• Pitch (speed) control• Play tones (no files needed)• Simple TTL serial control interface (non-inverted) (Logic level – RS232)• SPI control option• 2400 bps to 460800 bps• 5 volt operating voltage• RoHS Compliant• Low power operation - less than 60mA @ 5V during playback - less than 30mA @ 5V idle• FAT12, FAT16 and FAT32 compatible - 8MB to 32GB and beyond• Read and write data files as well as audio playback• Easily interfaced with any microcontroller (PIC, AVR, 8051, etc.)Example application• Music, speech AND data storage for robotics• POP/Kiosk Audio Playback• Interactive Art• Portable MP3 player• Replace CD players in:o Phone systemso Amusement attractionso Commercial ambient audio systems• Halloween props• Museum and Science Centre exhibits• ... and much more!The firmware on the rMP3 can be updated through a bootloader, so you can take advantage of any newfeatures or fixes that may become available for the rMP3.Bart Huyskens Manual Elektor Proton V1.0 3 April 2011 92
• Supportso MMC, SDC, SDHC card formats.• All available card formats are supported. From 8MB up to 32GB.o FAT12, FAT16 and FAT32.o Long file names.o SD, miniSD, and microSD form factors.• AudioooooooMP3, PCM WAV, IMA ADPCM.MP3 CBR or VBR decoding.32 to 320 kbps MP3 bitrates.32, 44.1, and 48 KHz MP3 sample rates.1/8” Stereo jack for headsets (16+ Ohms) or for line-in connections.87 dB S/N ratio.• Control Interfaceo TTL serial host connection from 2400 → 460800 bps.o 8 bits, no parity, 1 stop bito SPI slave (TBA).o 7 bit with trigger interface (control up to 127 sounds).o 8 button/switch interface.• Configurable polarity, interruption and debounce modes.• File System Supporto Up to 4 file handles open simultaneously for reading and/or writing.o Random reads/writes.• You can read from or write to anywhere in a file.• Seeking in a file allows for file pre-allocation, leading to faster write times.o File truncation.o Change file modification stamp.o Change file attributes.o Iterated file listings with wildcards.• You can iterate through a directory listing with wildcards.o Direct file copy.• Copy data from one file to another directly.o On-board Real-Time Clock (RTC).• Files created/modified have time stamps updated to current time.o Configuration on card.• Settings can be read from a configuration file on the card.• Bootloader for firmware updates.• -40°C to +85°C operating temperature range.• TTL Serialo 8 bitso no parityo 1 stop bito no echoo 2400, 4800, 9600, 38400, 57600, 115200, 230400, 460800 bpso (factory set to 9600 bps)o (resets to 9600 bps after entering update mode)Bart Huyskens Manual Elektor Proton V1.0 3 April 2011 93
