I am looking for code to adjust the Microphone Gain via software, at least it is mentioned in the tech brief. On the linkit one any electret mic on the 3.3v line and a 1k ohm seems to work just fine, and it does not need a pre-amp anyhow i have a similar problem because i do need it to be more sensitive but if i dont need a pre-amp it really would be wonderful.
maybe you guys should check and see if the chips actually does have an built in adjust Gain function “and let me know” maybe simpler question is "has anybody heard of this built in function for the linkit one or any other platform ???
thank you
Louie.
