Other Parts Discussed in Thread: MSP-EXP430FR5994
Dear Sir/Madam,
I am using MSP430FR5857 micro-controller in my application . I am giving signal to coil of power relay (230V AC) to turn ON and OFF from microcontroller as per the code below
while (1)
{
delay_time(50000);// 5s delay after both LINE and NEUTRAL off
P3OUT|=BIT6 ; // Line Relay ON signal
delay_time(5000); //Delay of 500ms between Line and Neutral Relay ON signal
P3OUT|=BIT7 ; // Neutral Relay ON signal
delay_time(50000); //Delay of 5s
delay_time(50000); //Delay of 5s
delay_time(50000); //Delay of 5s
delay_time(50000); //Delay of 5s
delay_time(50000); //Delay of 5s
P3OUT &= ~BIT6 ; // Line Relay OFF signal
delay_time(5000); //Delay of 500ms between Line and Neutral Relay OFF signal
P3OUT &= ~BIT7 ; // Neutral Relay OFF signal
}
The issue is that micro-controller gets Reset some times when relay ON or relay OFF ,the reset issue is random . i am unable to find the reason for same and how to overcome it .
Please suggest some solution for the same . Hoping to hear from you soon.
