PWM doesn't seem to like working at 5v. At 0% it outputs ~3.5v but 25%, 50% & 75%, they all output 5.45v which is actually higher than 100% at 5.34v. Note that 1% operates at ~4.9v, but 10% also jumps to 5.45v. Guess I'll have to stick to the low/med/high switch on my USB powered dew straps.
What type of flat panel (cheap) would I need to test SkySwitch in that mode? Any suggestions Chris?

Hi Mark,
Firstly, you are doing a fantastic (I was tempted to say "stellar"

) job on this, thank you so much.
I'll do some more testing on the 5V PWM and get back to you on that one.
I think I know what is happening and I'll get back to you with the answer soon.
Can you tell me, are you using a multimeter/voltmeter to test the PWM output or something like an oscilloscope?
I've tested the flat panel drivers with both electroluminescent panels and LED based panels. I can send you a simple 12V LED panel that's about 120mm across if you have a scope around that aperture or less?
Chris
