Re: Experience?
My company had started seeing ghost digits on their multiplexed displays ...
Really, people haven't learned that on in the last ... ooh how many decades is it now ?
Back in the 80s when I was just a junior myself, one of my colleagues was doing some code for a new display. He had digit shadows and just couldn't understand why. It had never occurred to turn off the segment drivers before switching on the next digit driver - until I suggested he tried it.
And 7 segment LEDs weren't exactly new then.
