Re: How to use VS1063's I2S

This Wednesday we have updated the VS1063 Datasheet so that it better explains how to activate I2S.
For details, please read Chapter 10.13, I2S Output from the datasheet, available at http://www.vlsi.fi/fileadmin/datasheets ... 1063ds.pdf .

Kind regards,
- Henrik

Re: the frequency response of vs1053/vs1063

Both VS1053 and VS1063 are capable of recording audio with a straight frequency response upto 20 kHz. One example application that demonstrates this is the VS1053b WAV PCM Recorder application, which has a frequency response of +- 0.15 dB between 10 - 20000 Hz. The package is available for download ...

Re: Latest stable VSOS Kernel (0.22) now available

Dear forum members, We are proud to present you the official 0.22 release of the VSOS Kernel and its example applications. The feature list is pretty much the same that Panu wrote above, so I will not repeat it here. At least for the moment VSOS 0.22 and its example applications are a part of VLSI S...

VS1053 recording example

Hello! Here is a generic microcontroller example for generating your VS1053 recording machine. You'll have to create a few VS1053 interfacing functions for it to work (documented in the comments), but otherwise it is pretty standard C. Share and enjoy! - Henrik /* Example code how to implement VS105...

Re: VS1053 OGG Recorder problem

Hi All, Exist a flag to test if the VS1053's buffer overflows? Kind regards, Claudio Dear Claudio, the VS1053 Ogg Vorbis recorder does not have a flag to test for buffer overflow. However, if you use a low bit-rate profile like 16 kHz and low quality (e.g. quality 5 or lower), then even slow microc...

Re: initial conditions

Hello, Hi I'm a lot confused with the datasheet. I'd like to know what are the initial conditions of the vs1011e mp3 decoder, I mean, in the app note "vs10XXan" page 13 is the quick start up, in the topic 4.4 says "Writing to SCI" and I'd like to know what is SCI and how do I wri...

Re: Joining ogg files into one file

Greetings, I'm not sure where to post this question, but this forum seems to be the closest fit. This is certainly good enough a place. :) I am trying to join multiple ogg files together into one file. Various people suggest: cat file1.ogg file2.ogg > joined.ogg I can play all of joined.ogg with og...

Re: DREQ strange behavior and not finished Vorbis recording

Dear Clemente, may I chime in? To me it seems like your problematic code lies here: while( i < temp ) { /* */ sample = VLSIReadReg( VLSI_HDAT0); cWAIT_DREQ; *voggSample++ = (BYTE)sample >> 8; *voggSample++ = (BYTE)sample & 0x00FF; i++; // DelayMs( 1); } I think the problematic line is: *voggSamp...
