Hi

I can't compile the program correctly, it gives me the following errors

"

instead if I remove the dsp components everything is ok

Hi Ben

Did you find out why it can't compile when I insert the dspwavegenerator?

Regards

Hi Oscar,

Yes I've found the cause of the problem now and am on with fixing it.

Edit, should be fixed for you now

Hi Ben

Hi, I would like to dedicate this week to debugging the interface to try to make it work. Now I am able to compile everything correctly but the i2s port does not work. I have a logic analyzer to see what the i2s port is pulling out.

The settings are as follows
FS 48Khz
16 bit
Stereo

I will not select other modes because I have seen anomalous behavior with some configurations so I will focus on this which is still very common the clocks, as mentioned some posts before are ok.

Next to the esp32 I have my dsp with which I can generate the signals and compare them. For example, if with my dsp I generate all 0's on the output signal, actually with the logic analyzer I display all 0's.

Instead with esp32 I set all the buffer to 0 in output I have values ​​other than 0

Hi Oscar,

Brlliant hopefully together we can make this work correctly. Can you post your latest project so I can see exactly what you're doing and I'll have a play here and see if I can make sense of it. My logic analyser can parse I2S data so I'll try with that.

Hi Ben

I am attaching both the program and an excel table of the logic analyzer

Thanks Oscar,

Just noticed in your code you are likely leaving AUDIO_BUFFER_1[0] uninitialised and probably overflowing the bounds of the buffer too.

AUDIO_BUFFER_1[a+1] = 0

should instead be.

AUDIO_BUFFER_1[a] = 0

Testing on hardware now to see what I get here.

Hi Ben

Sorry for the stupid mistake!!! I have compiled again but continue to get values ​​other than 0 on the i2s signal

Yes there's something certainly up I cansee there is lots of random data appearing, not the data that is being written.

I'll keep playing with it and see if I can find a way to tame it.

ok

How are these parameters set by the driver?
channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT,
.communication_format = I2S_COMM_FORMAT_I2S | I2S_COMM_FORMAT_I2S_MSB.

Because these parameters must also be set in order to communicate in I2S standard.

I don't know if this rtos based example can help you https://github.com/SuperHouse/esp-open- ... _example.c
