AMC6821: Application: FAN speed control abnormal
Part Number: AMC6821
customer side would like to check the R.P.M reading of AMC6821 register whether match the real case FAN speed.
But the reading from 0x08 & 0x09 was always 0xff, may we know the how to read the speed correctly?
and from the tool set of EVM, we know could convert the RPM reading from register, but how is that work?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
