Expand description
@brief Reconfigure the I2S gpio for TDM 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 TDM mode, i.e., ‘i2s_channel_init_tdm_mode’ has been called before reconfiguring
@param[in] handle I2S channel handler @param[in] gpio_cfg Standard mode gpio configuration, specified by user @return - ESP_OK Set clock successfully - ESP_ERR_INVALID_ARG NULL pointer, invalid configuration or not TDM mode - ESP_ERR_INVALID_STATE This channel is not initialized or not stopped
