fc1ee2666a I2S: fixed support for 24 and 32-bits, fixed tx/rx at the same time and others in log:
Add support 24, 32 bits

@jxmao optimize i2s_zero_buffer

@jxmao correct config support slave mode

@jxmao correct setup pin support tx/rx at the same time

Enhance pin power

@jxmao add dynamic change number of channels

remove nvs_init

remove start log and enhance power pin setup

using enum for i2s_channel and i2s_bits_per_sample, return ESP_ERR_INVALID_ARG when check params

validate i2s_bits_per_sample and channel

check tx & rx buffer before fill zero

remove checking channel as @jxmao suggest

limit dma buffer

modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512

Add support 24, 32 bits

reduce push function

Modify sample can test with 24, 32-bits

Add i2s sample README

Fixed i2s_set_clk got reset sometime

can changes bit-wide while running

Fix sample rate calculation for DAC mode from @jeroen

modify example can change bits per sample every 5 seconds

cleanup

add comment for bytes_per_sample

update as @angus suggestions

Add i2s_set_clk api

I2S driver bug fixed as following log:

@jxmao optimize i2s_zero_buffer

@jxmao correct config support slave mode

@jxmao correct setup pin support tx/rx at the same time

limit dma buffer

modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512

limit dma buffer to 4092

change gpio_matrix_*_check to inline function, remove some comments and rename test_i2s function to setup_triangle_sine_waves

821c70f5d7 examples: Standardise naming of files, symbols, etc. in examples
* Use "example" in all example function & variable names,
  ie use i2c_example_xxx instead of i2c_xxx for example functions.
  Closes #198 https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

ecee175962 Merge branch 'bugfix/nvs_init_check_empty_pages' into 'master'
Error handling in NVS initialization

Previously nvs_flash_init worked under an assumption that there should always be at least one free page available. This is true during normal operation, but in some cases (such as when changing application partition table from a non-OTA to an OTA one), NVS partition may get truncated, which will cause empty pages to be lost.

This MR adds error checks for this condition, and updates code which calls `nvs_flash_init` to check for the return code.
For most examples, a simple `ESP_ERROR_CHECK` is added around `nvs_flash_init`. For NVS examples and the OTA example, more robust error handling is added.

This change also removes nvs_flash_init calls from examples which don't use NVS.
