i2s Bridge demo code

Libra — Tue, 13 Jan 2026 09:46:23 GMT

In i2s applications, I need to implement full-duplex data in and data out, but the demo code uses two separate i2s groups for this purpose.

Is there a way to implement full-duplex i2s using a configuration of WS + SCK + DATA_IN + DATA_OUT?

Thank you so much for your interest in our products and for using our community.

Please check RT685 user manual, each Flexcomm I²S interface can only configured for one direction at a time—either transmit (TX) or receive (RX).

If you want realize full-duplex, you need to use two Flexcomm, one configured as TX, and the other as RX.
