Hello,
I am driving an LED in series with a limiting resistor with a PWM generator in a PIC micro controller. It all functions properly, best I can determine.
I notice a surprising thing, that at only a 0.7% duty cycle, the brightness of the LED, though dim compared to full brightness, is much higher than I expected.
I tried several LEDs and current limiting resistors, same result.
It is so surprising, I am wondering is anyone can confirm my observation.
