Hello!
I’d like to add pdm mic (SPH0644HM4H), which has 2 pin: PDM_DCLK(gpioa_7)/PDM_DIN0(gpioa_8),
what can i do for A311d support this pdm mic?
I use android 。。。。。。。。。。
The PDM pin is not on 40 pin header, and it is on m.2 slot. How did you use it?
It need to modify a lot of source code if you want to add PDM support.
Thank you for your reply, we are using an external digital microphone, which has now been tuned
