Hi

I am working with "stm32l433ccu6" ARM processor and I got a serious problem which cause Hard Fault Error inside my firmware. The problem arise when I run PDM_Filter_64_LSB() function from libPDMFilter_CM4F_keil.lib which is already included in my project.

My compiler is  keil MDK-ARM version 5.14.0.0

1. I would appreciate for a kind of technical support.

2. Would you plz let me know if low power series are compliant with available PDM libraries in stm32_audio/Addons/ path or not?

3.Could you plz send me the source code of pdm filter,it might help me to debug current fault and solve the problem.
