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???????????
