Hello,
In our application we need on board mic, speaker (not earpiece) and headset mic and headset speaker.
We are doing above by using interface available in TPS65951:
On board
Mic: MIC.MAIN.P,MIC.MAIN.M
Speaker: Predrive outputs for 8 ohm speaker with class D amplifier (mono)
Headset:
Mic: HSMIC.P, HSMIC.M
Speaker: HSOL,HSOR
We need headset speaker and headset mic detection in the above explained application. We are using GPIO2 as suggested in TRM for headset speaker detection but for mic detection we are planning to use GPIO1 for it.
Would it be possible to use GPIO1 for the headset mic detection? If yes, is it possible to switch between on board and headset by software?
