Hi there,

I asked previously spoke about the problem I was having with my uC resetting at will.

I am now running the uC with the WDT being disabled, and it runs perfectly on the test bench with a 12V supply.

The problem is when I hook up the cct To a 110V switchmode power supply and the device that I am comtrolling.
In this case it runs well for a while then it stalls, lighting up LEDs on pins that I have not even programmed or enabled in the test code that I am running.
The very same LEDs are lit when it stalls, and it stalls in more or less the same spot.

When I take it back to the test bench, all is well again.
Does anyone have an Idea as to what is going on.
Any and all help is welcome.

Thank you for your time,
sun
