Hello,
We are using MAX31760 for our fan control.
For some reason readings from tachometer registers 0x52 - 0x55 not changes when we increasing speed of fans.
We checked signals on TACH1 and TACH2 and they ok. Square wave form 0-3v and frequency keep changing when we changing PWUN register 0x50 value.
What could cause this?
Thanks,
