VS1010 has hardware support for a great number of different devices and interfaces. However, getting them working tiogether will require some amount of customization for each project.
This page shows the currently existing VS1010 application template status. Each template requires some customization. At the very simples, it may mean defining customer-specific USB IDs, and a typical customization contains specifying a customer-specific user interface. Typically VLSI can do these customizations in a few weeks calendar time. Please contact us us for any project you might have to see how to best reach a common goal on them!
The page is divided into three sections:
- Existing: These templates exist as functional examples, and only needs per-customer customization.
- To Do: Still need work to be viable templates. If you need a schedule estimate, please contact us.
Existing
These templates exist as functional examples, and only needs per-customer customization.
Legend:
"+" Supported
"-" Needs customer-specific pieces of software
+ Example for how to make a basic MP3 audio player.
+ Easy to read code
+ Demonstration video also available
+ Low latency: 1 ms from I2S to USB. So I2S ADC and computer side buffering are biggest causes of delays.
+ USB audio class.
+ Pure direct: What ever the I2S is giving, it is passed to USB. No controls to accidentally break the signal.
+ DAC monitor: When Samples are going to USB, they are copied to DAC through DAOSET. (-6dB level), leaving stdaudioout for user programs.
+ Modest resource requirements: I 1151, X 234, Y 172 when example stats program compiled, I 964, X 126, Y 172 without stats.
+ 48kHz 16 bit
+ MP3 playback from SD card with incredibly fast indexing (indexes 20,000 mp3 files in about 6 seconds).
- MP3 playback from USB flash, implements USB host.
- USB DAC and USB mass storage modes.
- FM Radio input using low cost FM module.
- 2 stereo line inputs using VS1010 built-in ADC.
- Custom LCD, driven with GPIO pins, no LCD controller needed.
- Real time clock.
+ Allows independent Pitch and Speed control for playback of MP3 files
+ Applications: DJ usage (pitch and speed), language learning (speed), audio books (speed), karaoke devices (pitch)
+ Decodes alternatively MP3 audio or complete files
+ Example provided with trivial cipher that can be replaced
+ Records 8, 16, or 24kHz IMA ADPCM WAV at 32, 65, or 97kbit/s, respectively
+ Plays back own recordings as well as MP3 files
+ Shows up as Hi-Speed USB Mass Media device to PC for easy file copying
+ Simple user interface for the VS1010 developer board
+ Basic SD card player
+ File update using USB
- Custom user interface can be added with software
+ Multiple voice channels over shared RS485 link

Microcontroller Mass Storage Bridge Applications
- UART/SPI to SD card
- UART/SPI to USB Flash (VS1010 acts as USB host)
- UART/SPI to USB (VS1010 acts as USB device)
Microcontroller Audio Slave Applications
+ UART controlled music player
+ Can play from many types of memory (SD card, USB flash, NAND flash)
+ MP3/WAV/PCM streaming with DAC output
- AAC, WMA and OGG support possible, needs application review with VLSI
Sound Effect Applications
+ Voltage triggered sound/music player
+ GPIO triggered sound/music player
Real Time Clock Applications
+ Integrated RTC with alarm
- Low power sleep modes
