Issue :: Precision of the frequency measured is affected at higher rates of input(example: 2KHz)
I am using a input tick frequency of 62500 in my ICU config. I can use higher rate of tick freq. but in that case I will not be able to measure lower frequency, below are more details with tick frequency info.
62500 - I can measure from 1Hz
12500 - I can only measure from 2Hz
250000 - I can only measure from 4Hz.
I want to improve my accuracy at higher frequency rates with optimal tick frequency where I will be able to measure 1Hz as well.
Can you please give a more clear description of the issue, and your setup. Kindly mention which board , MCU are you using, what is the project about, what things (i.e. which peripherals) are being used, possible screenshots of the issue and code snippet to help us understand the issue better?
