vs1000/vs1005/vs1010 are NOT codec, they have only decoding functionality, i'm wrong?

Read and write audio data through SPI in the same time is not possible, so a lot af SPI access are required to have a real time full duplex implementation. My question is : can I use UART to read incoming audio and use SPI to send output audio in the same time? It is not an orthodox solution, but if...

correct!
play buffer was underrun. I changed code and now is perfect.
Thanks a lot!
Just a last queston:
My initial expectation was that when I send data to the decoder in the same SPI frame I read the encoded data.
is it possible to set this modality?
it will reduce dramatically the SPI access!

ohps, i simply forgot to set RM_63_CODEC in SCI_RECMODE.... :lol: Now it seems that codec has two different transfer rates. I have a circular buffer (now size is 16384 byte, my hope is to reduce it to 64) Read ponter starts ad beginner of buffer, write ponter starts in the midle of buffer (8k). It s...

do { // See if there is some data available if((n = vs_read_register(SCI_RECWORDS)) > 0) { for(i = 0; i < n; i++) { w = vs_read_register(SCI_RECDATA); bufferAudio[bufferWrite++] = (w >> 8); bufferAudio[bufferWrite++] = (w & 0xFF); bufferWrite &= BUF_MASK; DRV_SPI_Tasks(sysObj.spiObjectIdx0);...

Code is written but when I start full duplex the output audio is coming from input and not from DAC internal buffer. I suppose that I have to set correctly PLAY_MODE, AD_MIXER, PCM_MIXER but even after reading datasheet I'm still confused. can you kindly tell me the value to use for these register i...

nice!
REC and PLAY in two different functions is working fine.
I made 2 errors: patch not loaded and heather info with size not updated.
I'm so sorry...
Now last step, fullduplex!
I'll keep you update.

Hi, Before implement a real full duplex, I trying to implement record a playback in two different functions. I porting exaclty the souce code from 'vs1063an_playrec.zip' Unfortunately when i write (SCI_AIADDR, 0x0050) to start recording the PIN DREQ never go logic '1' Any idea? Thaks Luca this is my...

My project have to read UDP packet from ethernet and play them with vs1063. In the meantime it has to read audio from vs1063 and send back to ethernet (like a VoiceIP, ethernet telephone) I'm not able to find any example how to initialize vs1063 to have full duplex functionality (g.711/722) till now...
