gpio_num_t

BCK pin, input in slave role, output in master role.

i2s_std_gpio_config_t::ws

gpio_num_t

WS pin, input in slave role, output in master role.

i2s_std_gpio_config_t::dout

gpio_num_t

DATA pin, output.

i2s_std_gpio_config_t::din

gpio_num_t

DATA pin, input.

i2s_std_gpio_config_t::invert_flags

struct { uint32_t mclk_inv: 1; uint32_t bclk_inv: 1; uint32_t ws_inv: 1; }

GPIO pin invert flags.
