Hi, I have a project where the LPC932 opens and closes a mechanic solenoid valve through a relay, which inverts the polarity. Sometimes I get some "noise" and the micro controller starts oscillating. I have a RC filter at the Vcc line on the micro. The oscillation starts when I have the solenoid valve connected to the circuit. Otherwise the circuit works as expected. I know this is a software forum, but I thought maybe someone would have any idea on how to approach this issue. I need to prevent this oscillation when the solenoid is connected to the circuit.
Thank you
