Hi,
Trying to understand the difference between CM1 and CM2 (the DS and the AN do not contain many information about it), I found this post which makes sense.
In this regard it is not clear to me the difference between these two situations:
A) {Register, Value}
{0x00,0x01} //page 1 {0x34,0x40}, // leftP ->IN1L {0x36,0x01}, // leftN ->CM2L {0x37,0x00}, //rightP OFF {0x39,0x00}, //rightN OFF {0x3b,0x1d}, //left micpga {0x3c,0x1d}, //right micpga {0x33,0x68}, //mic bias
and B)
same as A) but
{0x36,0x40}, //leftN ->CM1L
With A) using CM2L I can hear the signal, with B) i.e. CM1L I can't.
Thank you.
