Figure 3 showed the ideal waveform for the LED current, which does not take the response time (t r) of the comparator into account. The t r of a comparator is the time it takes the output to change ...

“Charlieplexing” as a method of multiplexing LED displays has recently attracted a lot of attention because it allows you, with N I/Olines, to control N×(N–1) LEDs (reference 1 through reference 5).

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.

In my ideal digital world, of which I often dream, signal voltage margins are always positive, signal timing margins are always positive, power supply voltages are always within the operating voltage ...
