Detailed Description

I2S driver configuration structure.

Field Documentation

mck_pin

uint32_t nrfx_i2s_config_t::mck_pin

MCK pin number.

Optional. Use NRF_I2S_PIN_NOT_CONNECTED if this signal is not needed.

sdin_pin

uint32_t nrfx_i2s_config_t::sdin_pin

SDIN pin number.

Optional. Use NRF_I2S_PIN_NOT_CONNECTED if this signal is not needed.

sdout_pin

uint32_t nrfx_i2s_config_t::sdout_pin

SDOUT pin number.

Optional. Use NRF_I2S_PIN_NOT_CONNECTED if this signal is not needed.

skip_gpio_cfg

bool nrfx_i2s_config_t::skip_gpio_cfg

Skip GPIO configuration of pins.

When set to true, the driver does not modify any GPIO parameters of the used pins. Those parameters are supposed to be configured externally before the driver is initialized.

skip_psel_cfg

bool nrfx_i2s_config_t::skip_psel_cfg

Skip pin selection configuration.

When set to true, the driver does not modify pin select registers in the peripheral. Those registers are supposed to be set up externally before the driver is initialized.

Note

When both GPIO configuration and pin selection are to be skipped, the structure fields that specify pins can be omitted, as they are ignored anyway.
