Part Number: MSP430FR2311 Tool/software: Code Composer Studio Dear all, I am detecting 240 V AC mains using optocoupler. Here is my circuit. When I am doing this my microcontroller resets every time I on/off the 230V AC circuit. I've seen response of the on & off switch in oscilloscope. It is looking like below image Because of this transient my controller gets reset as the same transient is being seen in the reset pin and power pin of the controller. Can anyone help with how to reduce this transient. I've tried low pass filter at output side by adding 330Ohm resistor with 10uF capacitor. Did not worked. Any help would be appreciated Thanks Abhishek
