BRTOS Demo - Playing a wave file from SD card on KwikStik

[gustavod]

We would like to announce our very first demo of a music player running on KwikStik kit.

In this demo we just alternate between showing the system uptime and playing a wave file from the root of the SD card (teste.wav - provided with this demo). For now we support just wave files of 8,000 Hz 16 bit PCM. We intend to support another wave formats and, if possible, mp3 files.

Moreover, we intend to implement play, pause, stop and volume commands in the terminal to play the wave and mp3 files. And, in the future, implement a music player  regardless of the USB CDC terminal.

We hope that you like it.

I forgot to say that you must activate, build and write the FLASH Segger J-Link version.
