This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
Replaced hyphens with underscores in examples
project definition for all examples which had
hyphens in their project name. dpp-enrollee is
an exceptions because the name matches the
project directory name while the project
directory also contains hyphens.
1. Support i2s on esp32c3 and esp32s3
2. Refactor i2s_config_t to avoid breaking change
2. Fix a bug that receiving unavailable values from message queue when dma queue has been re-allocted
4. Support i2s unit test on esp32c3 and esp32s3
using apll_param to setup APLL
new apll calculation method, much faster
validate freq calculation
Ensure that the i2s frequency is greater than the hardware limit
Add description of how to calculate apll clock, support apll for other 16-bits audio, check rev0 chip
correct space
I2S driver - fixed support for 24 and 32-bits, fixed tx/rx at the same time
- Modify sample can test with 24, 32-bits audio
- Add i2s sample README
- simply i2s_push function
- change sample rates, bits per sample, channel on fly
See merge request !483
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:

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
for change commit title
* Use "example" in all example function & variable names,
ie use i2c_example_xxx instead of i2c_xxx for example functions.
Closes#198https://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
