Hi Dears



I use STM32F405 as MicroController and I have some problem in hardware.

For example i design a circuit with STM32F405 and i supplied it with HI-LINK power supply module.

When I connect some devices into a power outlet ، microcontroller does unwanted things but it dosent RESET.

I putted some filters that contain capacitors and inductors.

I changed my clock source and i reduced the system core clock 

I use 16 MHZ oscillator to increase stability. 

But the problem is not resolved.




How can i resolve this problem???????????


thank you
