We're designing a portable digital audio player with a unique interface for audiophiles. This project consists of developing an embedded software solution on a Microchip PIC32MX series microcontroller, with the following requirements. SOFTWARE REQUIREMENTS INCLUDE: 1) Decode audio files (.WAV, .MP3, .FLAC, .OGG) and playlists (.PLS) stored on a micro-SD card. Must support modern file systems, including 256GB SD cards and long filenames. 2) Output decoded digital audio data via I2S. Must support at least 24-bit, 192kHz sampling rate I2S. Software solution preferred, or use VLSI Solution's VS1053, or equivalent. 3) Send and receive commands to user interface app, via BC127 Bluetooth module or equivalent: -Support Play, Pause, Stop, Previous, Next, Shuffle, Random, -Read playlists, filenames, and directories of SD card (basic file-system navigation) -Read ID3 tags, including embedded artwork PROJECT DELIVERY SHALL INCLUDE: A) Source and compiled Microchip MPLAB project, with all software requirements implemented. Source code shall include thorough explanatory comments. B) Basic Android and/or iOS app to demonstrate solution. C) Pinout and/or hardware schematic of your PIC32MX solution. D) Demonstration of final solution.

Hi. I'm experienced developer. Also have done similar projects done. You can look my portfolio. Some questions. > Decode audio files (.WAV, .MP3, .FLAC, .OGG) if need i can research that AAC can be added too. > Must support modern file systems which FS you mean: F2FS, NTFS, Ext-family etc? > Software solution preferred and i recommend to use it. > Read ID3 tags, including embedded artwork player has no indicator so all this information must be showed in mobile app. I'm right? > Basic Android and/or iOS app to demonstrate solution. I can write Android app. > Pinout and/or hardware schematic of your PIC32MX solution. I can develop develop whole device and provide: scheme, pcb layout, documentation for manufacturing and setup device. > Demonstration of final solution. I'll provide video demonstration. Also can provide spectral analysis of player in compare with original file. Terms: 1-2 month, $2500.

Hi Sir, I'm embedded engineer from Vietnam. I have more than 6 years working in embedded system including design, PCB and implementation. I used to work with TI's C5000, STMF3 and dsPIC33. Especially, I worked on audio processing using TI's C5535 DSP. So I do confident that I could handle your project completely. BTW, I have worked for several outsourcing company before. Now, I'm trying to build my own business. I hope we could work for you in this project and could build long-term relationship. You will get my highest responsibility. you could contact me via Skype: truonglyt Thank you. Regard, Truong
