when is going to be implemented for I2S ADC DMA ?

Postby mbalci » Wed Aug 29, 2018 1:01 pm

Hello,
When i open i2s.h file there is such code ;

Code: Select all

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=#FF0000] //I2S_MODE_ADC_BUILT_IN = 32,     /*!< Currently not supported yet, will be added for the next version*/[/color]
    I2S_MODE_PDM = 64,
} i2s_mode_t;
So as i understand I2S_MODE_ADC_BUILT_IN not implemented yet. So when will it be available ?Which is the next version ?
Is there any platform that i can use I2S_MODE_ADC_BUILT_IN ?

Which version of IDF are you using? This mode is supported in current stable version, 3.0.3.

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 ?

Code: Select all

https://github.com/platformio/platform-espressif32/releases
And how install this file in to the arduino because platform-espressif32-1.3.0.zip file includes py files.
