Re: My first question

Hi, and welcome to the forum!

Have you taken a look at the VS1000 module? It allows you to store ogg sound files in the included SPI flash or on an SD card and play them using GPIO pin triggers or serial commands? It's one option on how to do it.

Re: VS1053 decode streaming USB audio?

You mean something like PCM, 16-bit, 48 kHz? Yes, as far as you can feed it to the VS1053 from your microcontroller without too many glitches. The main problem is flow control. Remember that you must control the sample rate by providing isochronous feedback to the PC. The alternative is to fine tune...

Re: VSIDE v2.46 example solutions not compiling.

Hi!

Usually this error occurs when there is another microcontroller development tool installed in the PC and the MAKE program from that tool in run instead of the MAKE program supplied with VSIDE, for some reason. Do you think this might be the case in your case?

Re: Couple Quick VS1005 Questions from New Guy

Hi, and welcome to the forum! The maximum I2S output rate from VS1005 when using the hardware modulator is 192/16 or 96/32, which both have the same bitrate. You can set 48/32, which is what you want. Then I2S_FRM (LRCLK) frequency will be 48 kHz, and each frame will carry two 32-bit samples, one fo...

RTC aware file copy

This program copies a file to a new file and runs RTCREAD to update the system time from RTC hardware so that the target file has a correct date and time, if the RTC has correct date and time. Does not create long file names.

usage:
copy d:fromfile.ext d:tofile.ext

Set VS1010D RTC time from file system

Dear all, Here's a VS1010D utility program to set the current time of the RTC to whatever is the latest file creation or modification time in a given directory, if it's later than the current time of the RTC. Usage: SetTimeFrom [?][!][folderspec] Folderspec can be a drive such as S: or D: or a subdi...

Re: VS1000 vs. VS1010

Hi again! Right.. SPI flash and SPI NAND flash are two totally different things and indeed there are 128 megabyte (1 gigabit) SPI nand flash chips in the market, and even larger ones. Ok, so here's the deal. In the ROM, there's no support for SPI NAND flash, but support can be added with a custom VS...

Re: VS1000 vs. VS1010

Hi! Hmm... VS1000 is an old IC, VS1010 is new. Cost is similar. VS1000 is a monolithic target, e.g. it runs one statically linked image. VS1010 has an operating system (VSOS) with built-in filesystem drivers and executes programs from a FAT filesystem (SPI flash or SD card). Both allow SPI flashes w...

Re: ADC solutions for real time parameter control?

Yes, there is SAR AD converter (Successive AppRoximation), a few ch, 10 bits (or 12?)
