Not sure I understood what you did there, but I'll have a closer look this evening.

Re: ESP32 Webradio

Still no good new for the i2s driver in 32 bit mode Interesting - since I couldn't get it to work in 8-Bit mode either, maybe theres a bug in the driver somewhere? If your HTTP connection gets dropped after some time, it can be a sign that you're reading too slowly and the server has to kick you ou...

Oops you're right, that only works if some freertos config option is changed in menuconfig. Fixed it.

Re: ESP32 Webradio

The built-in one? It has only 8 Bit resolution, but still better than the ~5 Bit of hacked PWM of the ESP8266 predecessor project.
The hardware codec I used has... I don't know, 16 Bit?

ESP32 Webradio

I was a big fan of Sprite_TMs https://github.com/espressif/ESP8266_MP3_DECODER project, and so I ported it to the ESP32. Go and get it here: https://github.com/MrBuddyCasino/ESP32_MP3_Decoder I made a picture, but Github currently refuses to serve blobs it seems: https://github.com/MrBuddyCasino/ESP...

Use I2S in I2S_MODE_DAC_BUILT_IN Mode

I found the sample code in i2s.h, and noticed that we can use the built-in DAC to render I2S audio. However I can't seem to get it working. This is my init function: static void init_i2s_dac() { i2s_config_t i2s_config = { .mode = I2S_MODE_MASTER | I2S_MODE_TX | I2S_MODE_DAC_BUILT_IN, // Only TX .sa...

Re: How to set unique id of each esp32

Be aware that Blufi has changed considerably in master branch and works differently than in the 1.0 SDK. So far no one has figured out how to use it.

Re: LoadProhibited Exception in driver/i2s.c

I'm using this one: https://www.adafruit.com/product/3006 Doesn't need MCLCK, works great. It would be nice though to see that the data is actually clean and I'm not loosing precision due to signal integrity issue, which definitely is an issue with the speeds I2S operates at (at least on a breadboar...

Re: LoadProhibited Exception in driver/i2s.c

I'm only using 16 Bit / 44,1kHz and only got it to work since yesterday.
My Rigol DS1054Z has no I2S decoder afaik, how do you verify the data?

Re: LoadProhibited Exception in driver/i2s.c

Ok, I think I've found the issue. The I2S subsystem was called from another location which sent a zero address while attempting to fill the DMA buffer with silence.

Sorry!
