Multiple SPI masters support in Arduino

I don't want to use SS becasue of performance isssue.

Re: ESP32 Arduino core roadmap

Regarding I2S — we still need a driver on the ESP-IDF side, and possibly a chapter in the Technical reference manual, before Arduino library can be written. Good news is that there is now an official I2S library, so at least we don't have problems choosing an API for that. When the officia I2S libr...

Re: ESP32 I2S input and output interface

When the document will be avaiable? The external codec I want to use need MCLK (master clock) from ESP32, do you have any suggestion?


Thanks!

Re: ESP32 I2S input and output interface

When the document will be avaiable? Has Espressif qualified I2S and I2C interface internally? I just want to know if I2S interface is working or not.
BTW, if I want to get MCLK (master clock) from ESP32, how can I get the signal? Thanks!

Regards,
Puter

ESP32 I2S input and output interface

Hi, All We are building a system using ESP32 chipset. The chip supports both I2S input and output, but till now we cannot find any detail information about ESP32 I2S interface. Is there any guys from Espressif can describe how to use the I2S interface? If the formal document has not been ready, it's...
