To win: three digital audio development boards from Future Electronics
November 30, 2012 // Julien Happich
This month, technical broadline distributor Future Electronics is giving away three of its Audio Streamer Micro-Blox development boards, worth USD 350 each, for EETimes Europe's readers to win.
The development board features an ARM Cortex-M4 microcontroller with audio file decompression software, a choice of high-end and low-cost DACs, a codec, and digital and analogue microphones. By using the board's free PC-based graphical user interface, which connects to the board via USB, developers can start recording and playing back audio files in minutes. The board also provides a hardware environment in which to develop code and evaluate the performance of ARM Cortex-M4 application software.
At the heart of the new board is the MK60N512VMD100 microcontroller from Freescale, with the free MQX real-time operating system and a free USB stack pre-loaded on the MCU. For system-level prototyping, it can be interfaced to Future Electronics LongBow Future-Blox motherboard. The boards software uses the ARM DSP CMSIS library, which has been optimised for the DSP co-processor available on the ARM Cortex-M4 core. Audio file decoding software embedded in the microcontroller can handle MP3, FLAC, WAV and Ogg Vorbis file types.
FLAC, a 'lossless file format, is becoming popular in hi-fi equipment in which excellent sound reproduction and very low distortion are of paramount importance.
Ogg Vorbis, by contrast, is an open-source, royalty-free file format that achieves tighter compression than MP3, and thus is used in embedded and industrial audio applications in which the emphasis is on reducing the requirement for memory. The powerful K60 microcontroller also has ample processing power to run other software for decoding files such as ALAC, WMA, AIFF and AAC. An Ethernet connection for file downloading is provided via the KSZ8031RNL, a small, low-power Ethernet transceiver from Micrel.
