Re: Simple Plugin for VS1053 as slave - HDAT1 zero

Thanks a lot Pasi.

I'll try it and test.

I am going to take you informed.

Btw, I've just received the book VS1053B from VLSI.

BR,
Lorenzo.

Plugin development - Interrupt advice

Hello. I was wondering if it was possible, in a plugin, to intercept changes of the SCI_ * registers required by a write made by an MCU via SPI. The intention is not to change the behavior of the ROM in correspondence with a change in the registers, but only to be informed about which register has b...

Re: Simple Plugin for VS1053 as slave - HDAT1 zero

To get 16kHz, the ADC itself will be set to 48kHz, then the result is decimated by 3. The ROM has a decimator function that can do 2:1 and 3:1 decimations directly from the ADC FIFO. However, the example doesn't include this, so I'll need to copy that from the ROM source code (and test it). Thanks ...

Re: Simple Plugin for VS1053 as slave - HDAT1 zero

Hi Pasi. Thanks again. You are very polite and extremely clear in explaining. I honestly think that products like the VS1053 are extremely powerful mainly because many people wants to use them also as slave codec and program by themselves the internal DSP. Posts like this you are involved in, permit...

Hello Pasi. Sorry for still bothering. .sect data_y,bsspace .org 0x1000 .export _bsspace _bsspace: .bss 0x400 .end Could you please explain me the differences in doing this buffer memory reservation in ASM code instead of doing it in C code declaring buffer in Y memory? Is it for efficiently reasons...

Re: Simple Plugin for VS1053 as slave - HDAT1 zero

Hi Pasi.

Great!!

Now, I am able to read samples from SPI.

I have not yet listen what acquired but, right now, I made a much important step forward!!

I will inform you about listening result but thanks a lot, really, for your help.

Best regards,
Lorenzo.

Re: Simple Plugin for VS1053 as slave - HDAT1 zero

Hi Pasi. Thanks for the reply. I think your ultimate aim was to determine from the ADC data in the vs1053b if it should raise some GPIO pin to wake up the controller, right? Not only. When in normal mode, the controller must receive all PCM linear samples from ADC via SPI in order to send them via W...
