CCS / TIDC-CC3200MODLAUNCHXL:WIFI AUDIO APP + SPI FLASH MEMORY

Hello, dear Kristen
thanks for the answer

1) Yes, I have successfully run the Wifi_audio_app example
2) Yes, I read the data from the flash correctly, I checked with a logic analyzer
3) Yes, I use one device and I want to understand how to correctly use this part of the scheme: -> I2S Driver -> AUDBOOST

Waiting for your reply

Hi Kristen,

Thank you very much for your answer!

If it's not hard for you, answer a few more questions:

1) I did a cycle of reading spi and sending it to PlayBuffer one bit at a time. If you send more than one bit (at least two), the program hangs.

Question:

Do I need to write to the RecordBuffer, and then use the command:

lRetVal = FillBuffer (pPlayBuffer, \
           (unsigned char *) (pRecordBuffer-> pucReadPtr), \
                                                 PACKET_SIZE);

send to PlayBuffer, or write from SPI to PlayBuffer directly?

2) Can you explain how this function works:

UpdateReadPtr(pRecordBuffer, PACKET_SIZE);

Now my program works like this:
I read SPI FLASH and write to pRecordBuffer, then I send it to pPlayBuffer using the "FillBuffer" command, then (as I think) I update and zero pRecordBuffer with the "UpdateReadPtr" command. All this in the "for" loop, in which 34933 iterations in each occur with one bit.
And I hear wheezing and hissing.

3) Do I need a delay in each iteration or should the loop take place without pauses?

So, you have already helped me, thank you very much for your answers

Sorry for my bad english
Best regards,
Georgiy
