WM8960 I2S + EasyDMA

[Sunil vignesh]

Hi,

I am trying to interface WM8960 CODEC with nRF52832 using (I2S and I2C) .

I am able to communicate with IC with TWI

I want to transmit the const uint16_t wavedata[] = {...........} which is greater than 50000 data . wave_data.h

I have tested this file with STM using the function HAL_I2S_Transmit_DMA(&hi2s1,CurrentPos ,(uint16_t)(DMA_MAX(AudioRemSize));

I want to use I2s transmit in nrf52

How to enable easyDMA here. and sending the data with the desired size;

Hello,

How to enable easyDMA here. and sending the data with the desired size;

Please see the I2S example for a demonstration of how to use the I2S peripheral.
I would recommend that you use nrfx I2S driver instead of the HAL functions directly.
The I2S peripheral always uses easyDMA.
