Expand description
@brief Reconfigure the I2S GPIO for PDM TX mode
@note Only allowed to be called when the channel state is READY, i.e., channel has been initialized, but not started
this function won’t change the state. i2s_channel_disable
should be called before calling this function if I2S has started.
@note The input channel handle has to be initialized to PDM TX mode, i.e., i2s_channel_init_pdm_tx_mode
has been called before reconfiguring
@param[in] handle I2S TX channel handler @param[in] gpio_cfg PDM TX mode GPIO configuration, specified by user @return - ESP_OK Set clock successfully - ESP_ERR_INVALID_ARG NULL pointer, invalid configuration or not PDM mode - ESP_ERR_INVALID_STATE This channel is not initialized or not stopped
