that was an easy test...as expected - same behaviour - connected Emitter to LM2940 centre pin (GND) rather than Vss line.

I was looking at that power supply too but couldn't read the number looked like FM-10-12.
P12 clears shows a 16 msec width step function (+5VDC, 0VDC, +5VDC) every 2 seconds as shown in the attached files.....this is clearly coming out of P12. Bob, I did do as you suggested, which is to place P12 into a high mode at the very beginning of the code, line 1, and then use the "END" command directly afterwards. Again, it shows this same behavior.

ok, as part of the simple troubleshooting I put the END cmd inplace....instead i changed it to a do loop with a PAUSE 1 and...the flickering vanished.
Now to backtrack and see if there is some related issue with my board....
Thanks very much,
