i just donwloaded arduino 1.8.5 then esp32 from some where .
So where can i get this IDF for arduino ? Is this correct link ? And how install this file in to the arduino because platform-espressif32-1.3.0.zip file includes py files.

Hello, When i open i2s.h file there is such code ; typedef enum { I2S_MODE_MASTER = 1, I2S_MODE_SLAVE = 2, I2S_MODE_TX = 4, I2S_MODE_RX = 8, I2S_MODE_DAC_BUILT_IN = 16, /*!< Output I2S data to built-in DAC, no matter the data format is 16bit or 32 bit, the DAC module will only take the 8bits from MS...

There's no filter we put intentionally in the signal path. The bandwidth of the ADC just is more-or-less 6KHz if you want a linear frequency response. So what is the conclusion ? what is the maximum sampling rate of adc in esp32? I could not see such information in datasheet , very interesting why ...

in i2s.h file there is such code ; typedef enum { I2S_MODE_MASTER = 1, I2S_MODE_SLAVE = 2, I2S_MODE_TX = 4, I2S_MODE_RX = 8, I2S_MODE_DAC_BUILT_IN = 16, /*!< Output I2S data to built-in DAC, no matter the data format is 16bit or 32 bit, the DAC module will only take the 8bits from MSB*/ [color=#FF00...

esp_rtos_sdk_example always building 0x00000.bin and 0x20000.bin files. i could not get 0x40000.bin file yet. ... i think , i solve the problem,for rtos sdk they changed base address to 0x20000 so 0x20000.bin seems the correct output ; You need to change these lines in make file ; Code: Select all f...

i can compile blinky2 example with "SDK_BASE ?= c:/Espressif/ESP8266_SDK" .
But i could not compile it by FREERTOS_sdk . Is there any example project to test directly for freertos sdk ?
