Re: Are VS10XX Plugins Standalone?

Hi, John, and welcome to the forum! I'm confused. Not trying to combine applications with plugins. I'm not talking about applications. Why do you mention applications? I think it's because you mentioned loading without a uC. And applications are loaded without uC. Plugins are basically always loaded...

Re: Does VS1053 Support i2s In and Out?

VS1053 I2S does not use the normal frame length and most i2s dacs can't handle it. VS1053 I2S uses 16 bits/sample, 32 bits/frame. Most i2s dacs expect 24/32 bits per sample and 64 bits/frame.

Re: Relationship between name and file number

How are names and numbers related, in alphabetical order, by the modification date or in some other way? By the order in which their entries are in the FAT directory. Unfortunately this is not guaranteed to be in any particular order and the order can change if files are created, deleted or modifie...

GpioCheckPins

Here's a small program, GpioCheckPins, which keeps printing the states of all GPIO pins until ESC key is pressed. It's useful for checking which pins your board's buttons are connected to. Pushing the buttons causes the corresponding number to change between 0 and 1. Here's the printout: VS1010>Gpio...

Re: VS1010 utility programs

DiskFree, ported from VS1005 VSOS 3.54 root sources to VS1010D. Here's a handy way to run DiskFree from your program: extern u_int32 scratch; ioresult main (char *params) { RunLib("DISKFREE","-p 1401 D:"); printf("D: has %ld kB free.\n",scratch); } And the result: VS1010>free D: has 959968 kB free. ...

Re: vs1063 full duplex speed up interface

My question is : can I use UART to read incoming audio and use SPI to send output audio in the same time? Yes. This is very clearly explained in the VS1063 datasheet, you really should read it. The bitstream generated by the encoder is fed to the Bitstream out FIFO. The data is then either read thr...

Re: vs1063 : g711/722 full duplex example

G.711 intercom telephone system application using MEMS microphone and VS1010 UART. vs1000/vs1005/vs1010 are NOT codec, they have only decoding functionality, i'm wrong? It depends. VS1010 is only decoder. VS1005 can do anything, if the correct software is available. VS1010 can do something simple, ...

Re: Slave device selection for mono audio and ARM microcontroller

Hi, and welcome to the forum! I think you will need a Li-Ion battery for your product. Draining 10mA from a CR2032 will give you only 2.5 volts, which is not feasible.. For example, playing 128kbps Ogg Vorbis on a VS1063, which is a slave IC, consumes 11mA for the core plus another 11mA for driving ...

Re: Corrupted files after use "fwrite"

Maybe important. As I've seen in terminal window, "currentBlockLoaded" was newer true.
Yes, very important. It shows that this is not the case.

We must look further. If you format the flash again, and start from the beginning, which step shows the first error?

Re: Problem with automation

Hi, thanks... but I cannot duplicate that test here. Could you give a set of test instructions that I can give to a technical person (trainee at VLSI) who is not a programmer, but knows how to use computers, so that he could do the test, and see what happens? -Panu Also, Have you tried the procedure...
