# Introduction

`VS1063` is an audio encoder/decoder from [VLSI solution](http://www.vlsi.fi/en/home.html). Base on VS1063 and STM32F1X, I'd designed a simple MP3 player. 

![MP3P-OFF](DOC/Pictures/vs-mp3.jpg)

# Specification

Here is list of main element used in my MP3P project:

- `VS1063a` as MP3 / FLAC decoder

- `STM32F103RCT6` as main controller 

- Can be powered from USB and Li-ion battery (without interruption on exchange)

- `TPS62110QRSARQ1`  as switching regulator (3v7 to 3v3)

- `MAX1555EZK` Li-ion battery charger

- `LTC4412ES6` Power Path controller 

- `SDIO` 4bit connection (which only 1bit got working!)

- Header pin for LCD connection (Compatible with Raspberry Pi hats)

# Notes

Here is some important notes about this project

1. There is an issue with SDIO and 4 bit connection. I can **NOT** get 4 bit mode working. So I tried to deal with 1bit mode. The problem show it self when you are decoding **FLAC** format. because of SD card slow interface, music can get slow! 

2. I think I should use pull-ups in SDIO data pins. But I'm not sure and I didn't try it till now!

3. Codes is `FW` directory is simple demo application, which play everything in root directory of SD card.

4. Before any decision about this board, as good friend said: **Check it yourself** !

5. Finally ... Have fun ...
