Came here to find out how to increase CM6530N PDM mic gain. In widows sound meter it barely hits 5 percent mark if I blow directly into the mic. I believe it is firmware related problem. As I read on the web there is cm65xx configuration tool to create firmware with desired configuration.
Where could I found copy of it? Thanks in advance!
