Need complete working prototype
No size layer limit for pcb
Needs to be completed in 6 months.
after pcb layout completed and shared with me , pcb will be manufactured by me and sent it to you for firmware development.
MC: STM32F767ZI
SRAM Buffer: IS61WV51216BLL-10TLI 3.3v
Storage interface: Sdcard slot 4bit SDIO
Output interface: independently-clocked I2S
audio clocks: NDK NZ2520SDA 49.152Mhz and 45.1584Mhz 3.3V
"wurth 693161011911" connector.
only i2s output
mute output.
Support pcm 32bit 768Khz and DSD512 audio files.
fatfs(exfat enabled) or ext4 [login to view URL] file system
uncompressed WAV, AIFF, DFF(DSD), AIFC-sowt formats, as well as an basic audio playback application, all in a plugin-based architecture
for future expansion.
Middlewares: decoders (FLAC, ALAC, MP3, AAC, Vobris,) and format containers (MP4, etc,)
wifi direct module (act like wifi ap) to view id3 tag and image, list, play, stop or edit(copy, delete) files in sd card over pc or mobile. Not plan to stream and play over wifi only for access edit and play files in sd card.
Do not decidec wifi module waiting your proposal.
I do not expect professional ui for the desktop and mobile app. Only need commamd sets and basic ui to make demo and test it.
Dear Sir,
I am an expert with more than 15 years of experience in Firmware development, prototyping, PCB Layouts and Engineering. I have worked in the past with 8-bit, 16-bit and 32-bit MCUs developing ultra-low power designs with complex algorithms.
I have checked the details of your work. I already have STM32F767 Nucleo board. I use Altium and design multi-layer PCB designs. I assure you the best solution for your work. Kindly contact me.
