Are there integration function library to do integration in STM32H745 ? Are there low pass filter functions that can be used for this problem? if yes , How to use the library functions in STM32 IDE?

[RKhel.1]

I am using ST microcontroller STM32H745Xi for Rogowski coil current measurement.

we are using Rogowski coil for current measurement. we have to detect the transient current .Due to Rogowski coil signal, amplitude is different (higher) at high frequencies(RoCo has derivation signal) in transient fault current signal. Transient signal may have burst of different frequency. Rogowski coil introduces 90 degree phase shift also amplitude of signal increase with frequency

We want to do integration of current signal from Rogowski coil so that we get exact transient current signal as injected .

We have following questions :

1. Are there integration function library to do integration in STM32H745 ?
2. Are there low pass filter functions that can be used for this problem?
3. if yes , How to use the library functions in STM32 IDE?
4. Let me know if any other solution is available?

Thanks and Regards,
