Re: I2S Receive bug causing garbage data?

@ BuddyCasino
Hey - just wondering if you had a chance to test it?

Re: What would you like to see in The Next Chip?

More RAM and many of the other items would be great. But if I'm going to be honest, I came to the ESP32 because of it's low cost and support for certain features like Wifi and I2S. The only other thing that would be great (outside of a linux env :)) is if everything worked correctly and the document...

Re: Did I brick it?

Have you tried erasing and re-flashing?

One suggestion would be to start with a known working sample. e.g.:
  1. cd into one of the sample - e.g.: "cd esp-idf/examples/get-started"
  2. completely erase the flash: "make erase_flash"
  3. Then make, burn and run the sample: "make flash monitor"

Re: I2S Receive bug causing garbage data?

Also tried capturing data while playing a louder sound. Again, note the left channel should be silent, but instead we have times where it's all 1's. As though the louder sound is "Pushing" more bits to the left channel... Raspberry - 32-bit Loud 0:00000000000000000000000000000000 | -966652416:110001...

Re: I2S Receive bug causing garbage data?

Here's some data with BITS_PER_SAMPLE set to 24-bit (the buffer is 32-bit). Again, note the left channel which should be silent.

Re: I2S Receive bug causing garbage data?

Running a test with the ICS-43432 gives interesting results with BITS_PER_SAMPLE (16) - NOTE: the data on the left channel on the esp32 (which I presume should be all 0's). Raspberry - 16-bit quiet 0:0000000000000000 | -3:1111111111111101 0:0000000000000000 | -2:1111111111111110 0:0000000000000000 |...

@ BuddyCasino >> Can you attach your code so I can re-check? Here you go!

Re: I2S Receive bug causing garbage data?

Hmmm, never received a reply so of 'course wondered if maybe it was a mistake/I'm crazy/don't understand - all of which is probably true :D. Went off on a few other issues, projects and wow, in a couple more months it'll have been a year! But coming back to it now, even after pulling the latest IDF:...

Where can we find your megaphone example?

Re: How to keep Wifi from timing out / multiple Curl calls example / wifi: pm start, type:0

@loboris - thanks! Looking through your example, there were a few things that I thought might fix it: Set WIFI_PS_NONE using: "ESP_ERROR_CHECK( esp_wifi_set_ps(WIFI_PS_NONE));". ** Unfortunately, it didn't seem to make a difference. Also, noticed that https://github.com/espressif/arduino-esp32/blob/...
